The '''cockatrice''', {{monsym|cockatrice}}, is one of the more complex creatures in [[Nethack]], and is generally considered to be a real nuisance, as it is often the source of many [[YASD]]s. It can [[stoning|turn you to stone]] [[instadeath|instantaneously]] if you touch it (or even its [[corpse]]) with your bare hands (or any other part of your body). However, if you are wearing [[gloves]], you can pick its corpse up and wield it as a weapon, turning enemies to stone instantaneously; the cockatrice corpse has been nicknamed the '''rubber chicken''' by the players who like to use it in this way. This is still extremely dangerous, as falling in any manner will cause you to touch it. Monsters with gloves can also wield cockatrice corpses against you.
+
A '''cockatrice''', {{monsym|cockatrice}}, is a type of [[monster]] that appears in ''[[NetHack]]''. It is an [[oviparous]], [[omnivorous]] [[animal]] that can be seen via [[infravision]], and is the namesake monster of the [[Cockatrice (monster class)|cockatrice]] [[monster class]].
 +
 
 +
The cockatrice and [[chickatrice]], collectively referred to as '''[[foo]]trices''', are among the more complex creatures in ''Nethack'': both monsters can [[Stoning|turn you to stone]] [[Instadeath|instantaneously]] if your bare skin makes contact with their body or [[corpse]], and this applies to other monsters as well.
 +
 
 +
A cockatrice has a bite attack, as well as a touch attack that can initiate stoning: to turn a [[player]] character to stone, the cockatrice's touch attack must land, and there is a {{frac|3}} chance of the cockatrice hissing - if hissing occurs and you do not have [[stoning resistance]], there is a {{frac|10}} chance that you will begin turning to stone. This effect will always occur on a [[new moon]] unless you are carrying a [[lizard]] corpse in open inventory. Turning to stone this way is a [[delayed instadeath]]: you lose any intrinsic [[speed]], and have a limited amount of time to cure the stoning before it turns you into a [[statue]].
  
The baby version of a cockatrice is a '''chickatrice''', {{monsym|chickatrice}}, and is similarly dangerous; while they may appear earlier than cockatrices, chickatrices are much weaker, rarer, and less likely to leave a corpse. Chickatrices and cockatrices are often collectively referred to as [[foo]]trices, particularly in reference to the stoning abilities they and their corpses possess.
+
Cockatrices possess [[poison resistance]] and stoning resistance. [[Eating]] a cockatrice corpse or [[tin]] will instantly turn you to stone unless you have stoning resistance - if you have stoning resistance, [[YAFM]] is printed and the meat has a {{frac|3}} chance of conveying poison resistance. Cockatrice [[egg]]s are also similarly dangerous: if a character eats one or is hit by one thrown by a monster, they suffer gradual stoning as with the aforementioned touch attack.
  
In addition to normal monster generation, floors below DL 17 may rarely generate [[cockatrice nest|a nest full of cockatrices]] as a [[special room]].
+
According to the definition in monst.c, eating cockatrice meat should convey [[stoning resistance]], but this is [[Deferred features|not yet implemented]].{{refsrc|src/monst.c|178|version=NetHack 3.6.7}}{{refsrc|src/monst.c|184|version=NetHack 3.6.7}}
  
== Hissing attack ==
+
{{upcoming|3.7.0|Lizard corpses no longer have any effect on the stoning attacks of cockatrices during a new moon.}}
If you hear the cockatrice's hissing, there is a chance that you may begin turning to stone. If you immediately act to counter this process, you can save your life, but any intrinsic [[speed]] will be lost. The hissing attack always succeeds during a [[phases of the moon|new moon]] unless you are carrying a [[lizard corpse]].
 
  
For a cockatrice to start turning you to stone, the following must all happen:
+
==Generation==
# The cockatrice must touch you with its petrifying touch attack. ('''"The cockatrice touches you."''')
+
Randomly-generated cockatrices are always hostile. A chickatrice can [[grow up]] into a cockatrice, and a cockatrice egg will hatch into a chickatrice.
# Then, there is a {{frac|3}} chance the cockatrice will hiss at you if it has not been [[Cancellation|cancelled]]. ('''"You hear the cockatrice's hissing!"''')
 
# Finally, there is a 10% chance (or 100% if today is a [[Time#Moon phase and date|new moon]] and you are not carrying a [[lizard corpse]]) that you will begin [[Stoning|turning to stone]]. ('''"You are slowing down."''' at the end of the current game turn)
 
  
[[Magic cancellation]] will not protect you against the hiss, although [[Cancellation|cancelling]] the cockatrice will prevent it from hissing ('''"You hear a cough from the cockatrice!"'''). Good [[AC]] can prevent a cockatrice from touching you. Note that cancellation's only effect on cockatrices is to block their hissing attack; it does not protect you against petrification due to contact with the cockatrice, living or dead. To prepare for the loss of intrinsic speed, you may [[tinning kit|tin]] the corpse of a [[quantum mechanic]] and eat the tin after stopping the stoning process, or zap yourself with a [[wand of speed monster]].
+
Hostile cockatrices can be generated with the [[summon nasties]] monster spell.
  
== Ways to be petrified by a cockatrice ==
+
The [[cockatrice nest]] [[special room]] contains several cockatrices and cockatrice eggs.
  
The following list gives the ways a cockatrice or chickatrice can kill you, and what there is to be done about it. (Except where otherwise stated, "cockatrice" will refer to both cockatrices and chickatrices.) This list may not be exhaustive.  All methods are instantly fatal and assume you are not stoning-resistant, unless noted. Wearing an [[amulet of life saving]] will save you if you are petrified.
+
A character that is not stoning resistant and is killed by HP damage from a cockatrice will leave a statue instead of a [[ghost]] if a [[bones]] file is created.
  
===Petrification by a corpse===
+
==Strategy==
 +
Both the chickatrice and cockatrice are generally considered serious nuisances, since they are the source of many [[YASD|stupid and annoying deaths]], the likes of which are [[#Footrice-induced deaths|listed below]].
  
====Always petrifies====
+
Cockatrices are stronger, slightly faster at 6 speed, much more common, and much likelier to drop corpses, but they tend to appear somewhat later than chickatrices. Use any and all [[ranged attack]]s at your disposal to bring down a cockatrice before it can get into melee range. [[Magic cancellation]] will ''not'' protect you against any of the stoning attack's stages, but good [[AC]] will prevent the cockatrice's touch attack from landing, and [[cancellation]] will prevent the cockatrice from hissing - note that it does '''not''' cancel any of the other stoning qualities of a cockatrice or its corpse, including the stoning caused by bare-skinned contact.
* Get hit by a monster wielding it (delayed death).{{refsrc|mhitu.c|916|version=NetHack 3.6.0}}{{refsrc|mhitu.c|1167|version=NetHack 3.6.0}} If you've killed a cockatrice near an enemy that can wield weapons, there is a high chance that one wearing gloves will pick up the corpse and attempt to stone you with it. Be on alert for messages involving the corpse being wielded. If you are blind and cannot see this information, it is best to assume they have wielded it. If an enemy has the corpse and you cannot kill it, you are advised to make your way to another level and wait for the corpse to rot away, which will take place in 250 turns. If a moat is nearby and you are wearing boots, you can kick the corpse into the water to make it inaccessible.
 
* Eat it. Gaining the [[food appraisal]] intrinsic warns you before eating dangerous food, including food that will petrify you. ('This smells like it could be something very dangerous!') The intrinsic is gained by reading a blessed [[scroll of food detection]], or casting 'detect food' at skilled or expert in divination spells. It lasts for one warning. If you have stoning resistance, it will give you a message 'This tastes just like chicken!' Keep food (especially cockatrice corpses) out of slot 'y'; this will help avoid accidentally eating something you shouldn't.
 
  
====Without wearing gloves====
+
Lizard corpses are among the most reliable cures for sudden stoning, as is the [[potion of acid]] (particularly for [[vegetarian]]s and [[vegan]]s); eating the corpse or tin of an [[acidic]] monster will also cure stoning, but you are not remotely guaranteed to get to such food in time. Note that merely biting into the lizard corpse cures stoning, allowing for one corpse to cure a few instances of stoning before it is fully eaten. You can prepare for the speed loss ahead of time by [[apply]]ing a [[tinning kit]] to create a [[quantum mechanic]] tin or keep a charged [[wand of speed monster]] in a [[bag]] or other [[container]].
* Pick it up. If you are polymorphed into a creature that lacks hands and can pick up objects, you will also be stoned.
 
** Exception: it's safe to pick up with a [[bullwhip]].{{refsrc|pickup.c|246|version=NetHack 3.6.0}}{{refsrc|apply.c|2514|version=NetHack 3.6.0}}
 
* Put it into or take it out of a [[container]].
 
* Try to throw or fire it.
 
* Wield the corpse.
 
* Snag it with a [[bullwhip]] or [[grappling hook]].
 
* Steal it (for example, when polymorphed into a [[nymph]]).
 
* [[Sacrifice]] it. This even happens when it's already lying on the [[altar]].
 
* [[Tin]] the corpse.
 
  
====Without wearing gloves, [[blind]]ed====
+
'''Do not''' attack a cockatrice if you are polymorphed into a form that uses bite, touch, sting, or tentacle attacks and is ''not'' stoning resistant - additionally, do not attack in the form of a monster that uses kicks if you are not wearing boots, and do not attack in the form of a monster that uses claws if you are not wearing gloves. Additionally, avoid [[riding]] while fighting a cockatrice if your steed is not stoning-resistant and has attacks that will cause it to touch the cockatrice - remember that attacks that miss you will sometimes fall upon your steed!
* Feeling the corpse when you move or teleport onto the square containing the corpse when not using {{kbd|m}}.
 
* Cease [[levitation|levitating]] over it when not using {{kbd|m}}.
 
* Look (using ':' at the square containing it).
 
* Get expelled from an engulfing monster on a square containing the corpse when not using {{kbd|m}}.
 
  
====Without wearing a [[helm]]====
+
{{upcoming|3.7.0|The corpses and tins of lizards and other acidic or stoning-resistant monsters confer temporary stoning resistance when fully eaten, keeping you safe from being turned to stone for the duration of the property.}}
* Throw it upwards (direction {{kbd|<}}). The death message is "petrified by elementary physics" (what goes up, must come down).
 
  
====Without wearing [[boots]]====
+
===As a weapon===
* [[Kick]] it.
+
If a character has [[gloves]], they can pick up and wield a footrice corpse as an extremely powerful weapon - but it can easily backfire on a character that does not treat it with caution. Monsters with gloves or stoning resistance can also wield cockatrice corpses to use against you or other monsters.
* Trip over it while [[fumbling]], as of [[NetHack 3.6.0]].
 
  
====Wearing gloves while wielding the corpse as a weapon====
+
Monsters hit with a cockatrice corpse turn to stone instantly, while a character hit by a wielded cockatrice corpse is subjected to delayed stoning and loss of intrinsic speed as above.{{refsrc|src/mhitu.c|995|version=NetHack 3.6.7}}{{refsrc|src/mhitu.c|1252|version=NetHack 3.6.7}} The corpse can be weaponized to dispose of almost any monster that lacks stoning resistance, up to and including powerful [[demon lords and princes]] - footrice corpses are nicknamed '''rubber chickens''' by players who like to use it in this way. However, you will instantly turn yourself into a statue if you fall or lose your gloves while wielding the corpse.
* Fall down the stairs. This happens if you are [[burdened]] or worse, are [[fumbling]], or are [[punished]]. However, you will never fall down the stairs if you are [[flying]].
 
* Fall down a pit, hole or a trapdoor, including jumping into them while [[flying]].
 
* Fall into a chasm created by a [[drum of earthquake]].
 
* Fall into a pit created by stepping on a [[landmine]]. If you are flying or levitating, you can pass over these without falling (except in [[Sokoban]]). Flying won't stop you from triggering the landmine, but it will prevent you from falling into the created pit. Jumping down a hole or trapdoor while flying ''will'' stone you.
 
* Fall onto a [[sink]] while levitating.
 
* Faint from hunger and fall on the corpse.
 
* Lose your gloves to disintegration by a [[scroll of destroy armor]].
 
* Lose your gloves to overenchantment (or underenchantment) by a [[scroll of enchant armor]]. If the enchantment on the gloves is +4 or higher, reading a non-cursed scroll of enchant armor may destroy them. If the enchantment is &minus;4 or lower, reading a cursed scroll of enchant armor may do the same.
 
* Lose your gloves to the monster spell destroy armor. [[Magic resistance]] protects you from this spell.
 
* Have your gloves taken off by a [[foocubus]]. You have {{frac|[[charisma]]|20}} chance of having the option to stop a foocubus from removing an item of armor. Cancelling them stops the seduction attacks altogether. Nymphs and [[monkey]]s cannot steal your gloves if you're holding a weapon; they will try to take your weapon first, petrifying themselves if successful. The corpse can be retrieved by breaking the resulting statue.
 
  
====Without wearing gloves, wielding the corpse while stoning-resistant====
+
One of the better methods of preventing YASD from a carried corpse is to unwield the corpse '''immediately''' after threats are dealt with, especially in areas where you have not checked for [[trap]]s. Keep a carried cockatrice corpse out of inventory slots that you use frequently, especially for food; gaining the [[food appraisal]] intrinsic warns you before eating dangerous food, including food that will petrify you, and can save you from an otherwise-fatal fat-fingering. For extra safety, you can simply bag the corpse or else drop it altogether.
* Change to a non-stoning-resistant form. [[Polymorph control]] or [[unchanging]] can prevent this. Reaching zero [[HP]] will change you back to your normal, non-resistant form if you don't have [[unchanging]], and kill you if you do.
 
  
===Petrification by a living cockatrice===
+
Additionally, keep away from sinks, [[foocubi]] and monsters with theft attacks (e.g. [[nymph]]s) if at all possible even while levitating - it is worth noting that a monster without gloves that steals your wielded corpse will turn themselves to stone, and a foocubus will always ask to take off your gloves if you are at 20 [[charisma]]. When wielding and using a footrice corpse, be prepared to switch to your main weapon when necessary: in addition to monsters that resist stoning out right, [[golem]]s that are [[#Footrices and golems|subjected to stoning]] will turn into [[stone golem]]s.
* Attack (strike, touch, or claw) it with bare, ungloved hands.
 
** Due to a bug, even the {{kbd|m}} command will not be safe if the cockatrice is shown only as a [[warning]] symbol.<!--Which version?-->
 
* Attack it with ungloved hands, wielding a [[potion]].
 
* Kick it without wearing boots (as a monster attack or as a command).
 
* Bite or sting it (monster attack).
 
* Headbutt it without wearing a helmet (monster attack).
 
* Hug it without gloves and a cloak (monster attack).
 
* Suck its brain with tentacles (as [[mind flayer]] or master mind flayer).
 
* Attack it while polymorphed into a [[foocubus]] ("You smile at the cockatrice seductively. You turn to stone...").
 
* Swallow it whole (as [[trapper]], [[lurker above]], or [[purple worm]]).
 
* Without gloves, attempt to saddle it.
 
* Without gloves, attempt to untrap it from a pit.
 
* Hear its hissing (delayed death). See {{sa|Hissing attack|sectionsign=true}} for details.
 
* [[Riding|Ride]] an animal that steps on a [[polymorph trap]] and turns into a cockatrice. Your [[magic resistance]] protects ridden monsters against polytraps.
 
* Get reduced to zero HP by its attacks. This will kill you normally, but if you weren't petrification resistant, you will leave a statue instead of a ghost in your [[bones]] file. If you were polymorphed into a stoning-resistant form while wearing an amulet of unchanging, you leave a ghost instead.
 
  
If you have no weapon or gloves, or are polymorphed into a form which has an unusual attack, cockatrices should not be directly attacked; attack them with ranged weapons or spells. If you suck a cockatrice's brain, you turn to stone. If your life is saved, you still suffer the delayed death stoning effects. [[Minotaur]]s are the only headbutters capable of wearing helmets (and even then, only cloth and leather hats). [[Salamander]]s are the only huggers capable of wearing both gloves and a cloak.
+
Take note of footrices killed near enemies that can wield weapons and either wear gloves or possess stoning resistance, and be on alert for messages involving the corpse being wielded - if a [[moat]] is nearby, you can use it to dispose of the corpse by [[throw]]ing it in (while wearing gloves) or [[kick]]ing it in (while wearing boots). If you cannot kill a monster wielding the corpse, [[levelport]] or otherwise escape the level and wait around 200-250 turns for the corpse to rot away. Using a [[bullwhip]] or [[grappling hook]] to snag a ''wielded'' footrice corpse will turn you to stone if you do not have gloves, but using a bullwhip to pick a corpse up off the ground is fine.{{refsrc|src/pickup.c|256|version=NetHack 3.6.7|comment=apply.c does not call the usual check when using the whip to pick up the corpse off the ground, but does call it when a weaponized corpse is snatched.}}{{refsrc|src/apply.c|2714|version=NetHack 3.6.7}}{{refsrc|src/apply.c|2849|version=NetHack 3.6.7}}
  
===Other ways to be petrified by a cockatrice===
+
===Footrice eggs===
* Eat a [[tin]] of cockatrice meat.
+
Cockatrice eggs can be stockpiled and used as makeshift "grenades" to instantly stone particularly troublesome monsters. One of the easier methods to obtain them is to lay them while polymorphed into a female cockatrice; it is also possible (but tedious) to obtain them via [[polypiling]] [[meatball]]s. Keep in mind that breaking your own laid eggs costs you 1 point of [[Luck]] per egg (up to a maximum of 5 at once).
* Eat a [[cockatrice egg]] (delayed death).
 
* Get hit by a cockatrice egg thrown by a monster (delayed death).
 
* Without a helmet, throw a cockatrice egg in the air (direction {{kbd|<}}; ''not'' a delayed death).
 
* Without gloves, smash a [[potion of polymorph]] over a monster, turning it into a cockatrice. (This is [[Bugs in NetHack 3.4.3#C343-31|bug #C343-31]], fixed May 2004)
 
  
== Use as a weapon ==
+
Like real eggs, cockatrice eggs need some special care, and an egg that is carried in open inventory will hatch after a short while - stashing the egg in a [[container]] (e.g. a [[sack]]) until their hatching time passes will ensure that you are not surprised by the hatchling and possibly stoned. You can test for a rotted cockatrice egg after retrieving it from the container by picking up more than one egg after; if they stack in your [[inventory]], they will not hatch.
  
A cockatrice corpse is an extremely powerful weapon, but can easily backfire and thus should be used with some caution.  To avoid falling in an unknown [[pit]], you should unwield it or be levitating when moving around in places that might have traps. Even if you are levitating and not fumbling (highly recommended), you should stay away from sinks, nymphs and foocubi to be perfectly safe. (But 20 Charisma makes foocubi safe.) Some creatures are immune to [[stoning]], and [[golem]]s turn into powerful [[stone golem]]s that can easily annihilate a character in the early game. So have a different weapon ready to use, and never stone a golem in the early game.
+
===As a wish===
 +
A footrice corpse or stack of footrice eggs is a good [[wish]] when dealing with especially tough monsters, or else where looking to deal with a significant horde as fast as possible (e.g. on the [[Astral Plane]]). The most ideal wish for the former is a a blessed partly eaten chickatrice corpse (chickatrices are lighter than cockatrices, and partly eaten ones are lighter still) - it is always worth banking a wish or two just in case of an unexpected deadly encounter. Remember that your quest nemesis and the [[Rider]]s are all immune to stoning.
  
Due to a minor [[bug#jabberwock|bug]], players polymorphed into a [[jabberwock]] will not stone monsters with a wielded cockatrice corpse.<ref>The exact condition for stoning a monster with a wielded trice corpse seems to be: (in natural form or (hit with weapon attack or hit with claw attack in slot 1 or hit with claw attack in slot 2 as a foocubus or hit with any attack in slot 1 as any L)). This also excludes some monster that cannot wield a weapon (adult [[dragon]], [[raven]], [[crocodile]], and the invalid polyforms [[Ixoth]], [[Demogorgon]], and the [[Chromatic Dragon]]).</ref>
+
Below is a quick list of stoning candidates:
  
== History ==
+
* Groups of hostile [[aligned priest]]s and the [[high priest]] of [[Moloch]]
 +
* Demon lords and princes minus Juiblex
 +
* The [[Wizard of Yendor]]
 +
* Strong [[angelic being]]s, including [[Archon]]s
 +
* Mind flayers and master mind flayers
 +
* [[Lich (monster class)|Liches]]
  
Before [[Hack 1.0.3]], a successful hissing attack was an [[instadeath]]; the only safe way to fight a cockatrice was with ranged weapons. The effect of the new moon first appeared in [[Hack 1.0.2]].
+
===As a pet===
 +
As pets, footrices are somewhat notable, though not especially desired: fully grown cockatrices in particular can easily defeat non-resistant monsters with a single bite, making it easy to retrieve loot from their statues. They are also omnivores, making them easier to feed directly in lieu of them eating their own kills (which naturally leave very few corpses).
  
== Wishing ==
+
===Footrice-induced deaths===
 +
Below is a non-exhaustive list of methods in which you can be killed by a live footrice, its corpse or its eggs, and methods of preventing these deaths - wearing an [[amulet of life saving]] will save you if you are petrified. All methods assume you are not stoning resistant, and are instantly fatal unless otherwise noted:
  
Wishing for footrice corpses can sometimes be a good idea when fighting tough monsters or a multitude of them. A good [[Astral Plane]] wish would be a blessed partly eaten chickatrice corpse&mdash;chickatrice corpses are lighter than cockatrices, and partly eaten ones are lighter still. All [[Quest nemesis|Quest nemeses]] and the endgame [[rider]]s are stoning resistant.
+
* Live footrices:
 +
** Be hit by its touch attack, which has a {{frac|10}} chance of inducing delayed stoning if it hisses.
 +
** While not wearing gloves, attack one using weapon or claw attacks while unarmed, or else with a touch attack.
 +
** While not wearing gloves, attack one with a wielded [[potion]].
 +
** While not wearing gloves, attempt to saddle one or [[untrap]] it from a [[pit]] or [[spiked pit]].
 +
** While not wearing gloves or a [[cloak]], grab and bearhug one (i.e. as a [[salamander]]).
 +
** While not wearing [[boots]], kick one (including via keyboard command or monster attack).
 +
** While not wearing a [[helm]], headbutt it as a monster.
 +
** Bite or sting it as a monster, including the seduction attack of a [[foocubus]] (which is <code>AT_BITE</code>).
 +
** Suck its brain with tentacles as a [[mind flayer]] or [[master mind flayer]] - if your life is saved, you suffer gradual stoning afterward.
 +
** [[Engulf]] and [[digest]] it whole.
 +
** Ride a tame [[steed]] onto a [[polymorph trap]] and turn it into a footrice.
 +
* Footrice corpses:
 +
** Be hit by a monster wielding one - this causes delayed stoning.
 +
** Without gloves, pick one up.
 +
** Without gloves, try to throw it, fire it, wield it, put it into or take it out of a [[container]].
 +
** Without gloves, snag a wielded one with a bullwhip or grappling hook - using the bullwhip to pick one up from the ground is fine.
 +
** Without gloves, steal one (e.g. as a nymph).
 +
** Without gloves, [[sacrifice]] it regardless of if it is on an [[altar]] or in your inventory.
 +
** Without gloves, apply a [[tinning kit]] to one.
 +
** Without gloves, move onto, teleport onto or stop [[levitation]] on a square containing one while blind and not using {{kbd|m}}.
 +
** Without gloves, [[near look]] via {{kbd|:}} while blind and feel a corpse on your square.
 +
** Without gloves, be expelled onto a square containing one by an engulfing monster while blind and and not using {{kbd|m}}.
 +
** Without boots, kick one or trip over it due to [[fumbling]].
 +
** Without a helm, throw one upward via {{kbd|<}} and have it land on your head - the cause of death is listed as "petrified by elementary physics" (what goes up, must come down).
 +
** With gloves, fall down a pit, spiked pit, [[hole]], or [[trap door]] while wielding one.
 +
*** This includes falling into a pit created by applying a [[drum of earthquake]] or setting off a [[land mine]], as well as doing so deliberately while [[flying]].
 +
** With gloves, falling down the stairs while [[burdened]], [[fumbling]] or [[punished]] and wielding one ''unless'' you are flying.
 +
** Having your gloves removed by a nymph or foocubus, or else having them destroyed, while wielding one.
 +
** With gloves, falling onto a [[sink]] while [[levitating]] or flying and wielding one.
 +
** With gloves, faint from [[hunger]] and fall onto your wielded corpse.
 +
** Without gloves, [[polymorph]] from a form with stoning resistance to one without stoning resistance while wielding one.
 +
* Footrice eggs:
 +
** Be hit by one thrown by another monster - this causes delayed stoning, as with being hit by a wielded footrice corpse.
 +
** Without a helm, throw one upward via {{kbd|<}} and have it land on your head, which does '''not''' cause delayed stoning.
  
Here is a quick list of monsters that can be good candidates for stoning.
+
===Footrices and golems===
* Moloch's [[Aligned priest|priest]]s and the [[high priest]] (especially in [[Moloch's Sanctum]] and the Astral Plane)
+
Golems other than the stone golem that are stoned by one of the above methods will instead become an animated stone golem - this includes you if you are polymorphed into such a golem.
* [[Demon princes]] and lords (except [[Juiblex]], who is stone resistant)
 
* The [[Wizard of Yendor]]
 
* [[Angel]]ic beings, including [[Archon]]s
 
* [[Mind flayer]]s
 
* [[Lich]]es
 
  
It's always a good idea to save up a couple of extra charges on your [[wand of wishing]] just in case. You never know when [[Demogorgon]] shows up or five [[Archon]]s are generated on the [[Plane of Fire]].
+
Early characters that cannot deal easily with hard hitters and/or lack reliable damage output would do well to avoid accidentally creating an annoying (or even lethal) obstacle out of a [[paper golem]] or [[straw golem]]. Conversely, stronger golems including the [[iron golem]] can be reduced to mere nuisances with a footrice corpse or egg.
  
== Resistances conveyed ==
+
==History==
 +
The cockatrice first appears in Hack 1.21 and Hack for PDP-11, which are based on [[Jay Fenlason's Hack]], and is included in the initial bestiary for [[Hack 1.0]]. In Hack 1.21, the cockatrice uses the {{white|C}} glyph; in Hack for PDP-11 and Hack 1.0, the cockatrice uses its current glyph.
  
According to definition in monst.c, eating footrice should convey [[stoning resistance]], but this is [[Deferred features|not implemented]].{{refsrc|monst.c|180|version=NetHack 3.6.0}}{{refsrc|monst.c|174|version=NetHack 3.6.0}}
+
From this version to [[Hack 1.0.2]], a successful hissing was an instadeath, and the only safe way to fight a cockatrice was with ranged weapons. Hack 1.0.2 also introduces the effects of the new moon.
  
==  Variants ==

[[Hack 1.0.3]] includes both gradual stoning and turns the dead lizard into a cure for the affliction.
  
In [[Slash'EM Extended]], touching a cockatrice with a non-covered body part isn't instantly fatal; rather, the same slow process of stoning is started that usually happens if you hear the cockatrice's hissing. The turns-to-live timer has also been increased, giving the player up to 7 turns to take action to stop the petrification.

Cockatrices are subject to a few bugs:
  
Also, in this variant eating a chickatrice will [[stun]] the player for 60 turns, eating a cockatrice may increase the player's [[intelligence]], eating a [[rubber chicken]] may increase a player's current and maximum [[Pw]], and eating a [[turbo chicken]] may grant a level-up.

A cockatrice is a mythical beast that features prominently in medieval bestiaries and English folklore, and is first mentioned in the 14th century John Wycliffe translation of the Bible, with the word used for the translation of various Hebrew words for "asp" and "adder" in the Book of Isaiah. The cockatrice appears as a two-legged serpentine creature with a rooster's head and bat wings; it is said to hatch from a rooster's egg, especially one incubated by a serpent or toad. and is reputed to be capable of killing with as little as a look, touch or breath.
  
The cockatrice is alleged to be incubated by a serpent or toad from a rooster's egg. Yolkless eggs were traditionally believed to have been laid by roosters.
+
The cockatrice has significant overlap with the mythical snake known as the basilisk: basilisks are said to be so full of venom that they leave a wide trail of deadly venom in their wake, and can similarly kill with a gaze; medieval bestiaries attribute chicken-like traits to the basilisk and popularized the idea of them being born from a chicken hatching the egg of a serpent or toad, which is the reverse of the cockatrice. Both also share a weakness to "weasels" (likely the mongoose, which had some immunity to snake venom) as well as their own reflected gazes and the crowing of roosters, and are likely based off the Nile crocodile - as a result, the basilisk and cockatrice referred to interchangeably (for example, the [[encyclopedia]] entry that both share in variants of ''NetHack''), and many languages still translate the term "cockatrice" as "basilisk" in some form.
  
Physically, it resembles a rooster with a reptilian tail and bat wings.
+
Modern incarnations of the basilisk and cockatrice, such as those seen in ''[[Dungeons & Dragons]]'' and various other fantasy media, characterize the creatures' lethal venoms as a petrifying substance that turned victims to stone, and later works portray them as distinct creatures: the modern cockatrice is a somewhat more bird-like creature as opposed to the fully lizard-like or serpentine basilisk. The cockatrice of ''Dungeons & Dragons'' debuts in the original 1974 white box as a weaker form of basilisk with a stoning touch and the ability to fly, and is further differentiated in later editions.
  
The traditional cockatrice is simply deadly. The stoning attack property comes from ''[[Dungeons & Dragons]]''.
+
Cockatrices can be found in almost any region, and typically prefer temperate or tropical regions, where they reside either underground or above ground in plains; some scattered numbers of cockatrices could be found in the Elemental Plane of Earth. Their beaks inflicted minor damage, but their bite could permanently turn creatures to stone - for a time, the petrifying aura could penetrate the Astral and Ethereal planes, much like basilisk gazes. Cockatrices are immune to their own petrifying bite and that of other cockatrices, but they are not immune to petrification through other means unlike in ''NetHack''. A cockatrice is very territorial and ferociously attacks perceived threats; flocks of cockatrices often attempt to overwhelm or confuse their opponents, and frequently flew at their faces.
  
The cockatrice is closely related to the [[basilisk]] (a monster not present in vanilla NetHack) referred to in the encyclopedia entry. The relation between basilisks and cockatrices is unclear; sometimes they are used as synonyms, but other times a basilisk is a different monster.

A cockatrice, c, is a type of monster that appears in NetHack. It is an oviparous, omnivorous animal that can be seen via infravision, and is the namesake monster of the cockatrice monster class.

The cockatrice and chickatrice, collectively referred to as footrices, are among the more complex creatures in Nethack: both monsters can turn you to stone instantaneously if your bare skin makes contact with their body or corpse, and this applies to other monsters as well.

A cockatrice has a bite attack, as well as a touch attack that can initiate stoning: to turn a player character to stone, the cockatrice's touch attack must land, and there is a 13 chance of the cockatrice hissing - if hissing occurs and you do not have stoning resistance, there is a 110 chance that you will begin turning to stone. This effect will always occur on a new moon unless you are carrying a lizard corpse in open inventory. Turning to stone this way is a delayed instadeath: you lose any intrinsic speed, and have a limited amount of time to cure the stoning before it turns you into a statue.

Cockatrices possess poison resistance and stoning resistance. Eating a cockatrice corpse or tin will instantly turn you to stone unless you have stoning resistance - if you have stoning resistance, YAFM is printed and the meat has a 13 chance of conveying poison resistance. Cockatrice eggs are also similarly dangerous: if a character eats one or is hit by one thrown by a monster, they suffer gradual stoning as with the aforementioned touch attack.

According to the definition in monst.c, eating cockatrice meat should convey stoning resistance, but this is not yet implemented.[1][2]

The following information pertains to an upcoming version (3.7.0). If this version is now released, please verify that it is still accurate, then update the page to incorporate this information.

Lizard corpses no longer have any effect on the stoning attacks of cockatrices during a new moon.

Generation

Randomly-generated cockatrices are always hostile. A chickatrice can grow up into a cockatrice, and a cockatrice egg will hatch into a chickatrice.

Hostile cockatrices can be generated with the summon nasties monster spell.

The cockatrice nest special room contains several cockatrices and cockatrice eggs.

A character that is not stoning resistant and is killed by HP damage from a cockatrice will leave a statue instead of a ghost if a bones file is created.

Strategy

Both the chickatrice and cockatrice are generally considered serious nuisances, since they are the source of many stupid and annoying deaths, the likes of which are listed below.

Cockatrices are stronger, slightly faster at 6 speed, much more common, and much likelier to drop corpses, but they tend to appear somewhat later than chickatrices. Use any and all ranged attacks at your disposal to bring down a cockatrice before it can get into melee range. Magic cancellation will not protect you against any of the stoning attack's stages, but good AC will prevent the cockatrice's touch attack from landing, and cancellation will prevent the cockatrice from hissing - note that it does not cancel any of the other stoning qualities of a cockatrice or its corpse, including the stoning caused by bare-skinned contact.

Lizard corpses are among the most reliable cures for sudden stoning, as is the potion of acid (particularly for vegetarians and vegans); eating the corpse or tin of an acidic monster will also cure stoning, but you are not remotely guaranteed to get to such food in time. Note that merely biting into the lizard corpse cures stoning, allowing for one corpse to cure a few instances of stoning before it is fully eaten. You can prepare for the speed loss ahead of time by applying a tinning kit to create a quantum mechanic tin or keep a charged wand of speed monster in a bag or other container.

Do not attack a cockatrice if you are polymorphed into a form that uses bite, touch, sting, or tentacle attacks and is not stoning resistant - additionally, do not attack in the form of a monster that uses kicks if you are not wearing boots, and do not attack in the form of a monster that uses claws if you are not wearing gloves. Additionally, avoid riding while fighting a cockatrice if your steed is not stoning-resistant and has attacks that will cause it to touch the cockatrice - remember that attacks that miss you will sometimes fall upon your steed!

The following information pertains to an upcoming version (3.7.0). If this version is now released, please verify that it is still accurate, then update the page to incorporate this information.

The corpses and tins of lizards and other acidic or stoning-resistant monsters confer temporary stoning resistance when fully eaten, keeping you safe from being turned to stone for the duration of the property.

As a weapon

If a character has gloves, they can pick up and wield a footrice corpse as an extremely powerful weapon - but it can easily backfire on a character that does not treat it with caution. Monsters with gloves or stoning resistance can also wield cockatrice corpses to use against you or other monsters.

Monsters hit with a cockatrice corpse turn to stone instantly, while a character hit by a wielded cockatrice corpse is subjected to delayed stoning and loss of intrinsic speed as above.[3][4] The corpse can be weaponized to dispose of almost any monster that lacks stoning resistance, up to and including powerful demon lords and princes - footrice corpses are nicknamed rubber chickens by players who like to use it in this way. However, you will instantly turn yourself into a statue if you fall or lose your gloves while wielding the corpse.

One of the better methods of preventing YASD from a carried corpse is to unwield the corpse immediately after threats are dealt with, especially in areas where you have not checked for traps. Keep a carried cockatrice corpse out of inventory slots that you use frequently, especially for food; gaining the food appraisal intrinsic warns you before eating dangerous food, including food that will petrify you, and can save you from an otherwise-fatal fat-fingering. For extra safety, you can simply bag the corpse or else drop it altogether.

Additionally, keep away from sinks, foocubi and monsters with theft attacks (e.g. nymphs) if at all possible even while levitating - it is worth noting that a monster without gloves that steals your wielded corpse will turn themselves to stone, and a foocubus will always ask to take off your gloves if you are at 20 charisma. When wielding and using a footrice corpse, be prepared to switch to your main weapon when necessary: in addition to monsters that resist stoning out right, golems that are subjected to stoning will turn into stone golems.

Take note of footrices killed near enemies that can wield weapons and either wear gloves or possess stoning resistance, and be on alert for messages involving the corpse being wielded - if a moat is nearby, you can use it to dispose of the corpse by throwing it in (while wearing gloves) or kicking it in (while wearing boots). If you cannot kill a monster wielding the corpse, levelport or otherwise escape the level and wait around 200-250 turns for the corpse to rot away. Using a bullwhip or grappling hook to snag a wielded footrice corpse will turn you to stone if you do not have gloves, but using a bullwhip to pick a corpse up off the ground is fine.[5][6][7]

Footrice eggs

Cockatrice eggs can be stockpiled and used as makeshift "grenades" to instantly stone particularly troublesome monsters. One of the easier methods to obtain them is to lay them while polymorphed into a female cockatrice; it is also possible (but tedious) to obtain them via polypiling meatballs. Keep in mind that breaking your own laid eggs costs you 1 point of Luck per egg (up to a maximum of 5 at once).

Like real eggs, cockatrice eggs need some special care, and an egg that is carried in open inventory will hatch after a short while - stashing the egg in a container (e.g. a sack) until their hatching time passes will ensure that you are not surprised by the hatchling and possibly stoned. You can test for a rotted cockatrice egg after retrieving it from the container by picking up more than one egg after; if they stack in your inventory, they will not hatch.

As a wish

A footrice corpse or stack of footrice eggs is a good wish when dealing with especially tough monsters, or else where looking to deal with a significant horde as fast as possible (e.g. on the Astral Plane). The most ideal wish for the former is a a blessed partly eaten chickatrice corpse (chickatrices are lighter than cockatrices, and partly eaten ones are lighter still) - it is always worth banking a wish or two just in case of an unexpected deadly encounter. Remember that your quest nemesis and the Riders are all immune to stoning.

Below is a quick list of stoning candidates:

As a pet

As pets, footrices are somewhat notable, though not especially desired: fully grown cockatrices in particular can easily defeat non-resistant monsters with a single bite, making it easy to retrieve loot from their statues. They are also omnivores, making them easier to feed directly in lieu of them eating their own kills (which naturally leave very few corpses).

Footrice-induced deaths

Below is a non-exhaustive list of methods in which you can be killed by a live footrice, its corpse or its eggs, and methods of preventing these deaths - wearing an amulet of life saving will save you if you are petrified. All methods assume you are not stoning resistant, and are instantly fatal unless otherwise noted:

  • Live footrices:
    • Be hit by its touch attack, which has a 110 chance of inducing delayed stoning if it hisses.
    • While not wearing gloves, attack one using weapon or claw attacks while unarmed, or else with a touch attack.
    • While not wearing gloves, attack one with a wielded potion.
    • While not wearing gloves, attempt to saddle one or untrap it from a pit or spiked pit.
    • While not wearing gloves or a cloak, grab and bearhug one (i.e. as a salamander).
    • While not wearing boots, kick one (including via keyboard command or monster attack).
    • While not wearing a helm, headbutt it as a monster.
    • Bite or sting it as a monster, including the seduction attack of a foocubus (which is AT_BITE).
    • Suck its brain with tentacles as a mind flayer or master mind flayer - if your life is saved, you suffer gradual stoning afterward.
    • Engulf and digest it whole.
    • Ride a tame steed onto a polymorph trap and turn it into a footrice.
  • Footrice corpses:
    • Be hit by a monster wielding one - this causes delayed stoning.
    • Without gloves, pick one up.
    • Without gloves, try to throw it, fire it, wield it, put it into or take it out of a container.
    • Without gloves, snag a wielded one with a bullwhip or grappling hook - using the bullwhip to pick one up from the ground is fine.
    • Without gloves, steal one (e.g. as a nymph).
    • Without gloves, sacrifice it regardless of if it is on an altar or in your inventory.
    • Without gloves, apply a tinning kit to one.
    • Without gloves, move onto, teleport onto or stop levitation on a square containing one while blind and not using m.
    • Without gloves, near look via : while blind and feel a corpse on your square.
    • Without gloves, be expelled onto a square containing one by an engulfing monster while blind and and not using m.
    • Without boots, kick one or trip over it due to fumbling.
    • Without a helm, throw one upward via < and have it land on your head - the cause of death is listed as "petrified by elementary physics" (what goes up, must come down).
    • With gloves, fall down a pit, spiked pit, hole, or trap door while wielding one.
    • With gloves, falling down the stairs while burdened, fumbling or punished and wielding one unless you are flying.
    • Having your gloves removed by a nymph or foocubus, or else having them destroyed, while wielding one.
    • With gloves, falling onto a sink while levitating or flying and wielding one.
    • With gloves, faint from hunger and fall onto your wielded corpse.
    • Without gloves, polymorph from a form with stoning resistance to one without stoning resistance while wielding one.
  • Footrice eggs:
    • Be hit by one thrown by another monster - this causes delayed stoning, as with being hit by a wielded footrice corpse.
    • Without a helm, throw one upward via < and have it land on your head, which does not cause delayed stoning.

Footrices and golems

Golems other than the stone golem that are stoned by one of the above methods will instead become an animated stone golem - this includes you if you are polymorphed into such a golem.

Early characters that cannot deal easily with hard hitters and/or lack reliable damage output would do well to avoid accidentally creating an annoying (or even lethal) obstacle out of a paper golem or straw golem. Conversely, stronger golems including the iron golem can be reduced to mere nuisances with a footrice corpse or egg.

History

The cockatrice first appears in Hack 1.21 and Hack for PDP-11, which are based on Jay Fenlason's Hack, and is included in the initial bestiary for Hack 1.0. In Hack 1.21, the cockatrice uses the C glyph; in Hack for PDP-11 and Hack 1.0, the cockatrice uses its current glyph.

From this version to Hack 1.0.2, a successful hissing was an instadeath, and the only safe way to fight a cockatrice was with ranged weapons. Hack 1.0.2 also introduces the effects of the new moon.

Hack 1.0.3 includes both gradual stoning and turns the dead lizard into a cure for the affliction.

Cockatrices are subject to a few bugs:

Origin

A cockatrice is a mythical beast that features prominently in medieval bestiaries and English folklore, and is first mentioned in the 14th century John Wycliffe translation of the Bible, with the word used for the translation of various Hebrew words for "asp" and "adder" in the Book of Isaiah.

Variants

xNetHack

In xNetHack, cockatrices generated at level creation outside of special rooms will have a few statues near them.

A cockatrice's hissing induces delayed stoning 15 of the time, and will have no effect if you are deaf.

Encyclopedia entry

Once in a great while, when the positions of the stars are
just right, a seven-year-old rooster will lay an egg. Then,
along will come a snake, to coil around the egg, or a toad,
to squat upon the egg, keeping it warm and helping it to
hatch. When it hatches, out comes a creature called basilisk,
or cockatrice, the most deadly of all creatures. A single
glance from its yellow, piercing toad's eyes will kill both
man and beast. Its power of destruction is said to be so
great that sometimes simply to hear its hiss can prove fatal.
Its breath is so venomous that it causes all vegetation
to wither.

There is, however, one creature which can withstand the
basilisk's deadly gaze, and this is the weasel. No one knows
why this is so, but although the fierce weasel can slay the
basilisk, it will itself be killed in the struggle. Perhaps
the weasel knows the basilisk's fatal weakness: if it ever
sees its own reflection in a mirror it will perish instantly.
But even a dead basilisk is dangerous, for it is said that
merely touching its lifeless body can cause a person to
sicken and die.
