The '''purple worm''' is a [[monster]] in [[NetHack]].  It is a popular [[pet]] due to its [[engulfing]] attack, which can kill any monster that is [[large]] or smaller in one hit ("Burrrrp!").
 
  
Purple worms will eat [[shrieker]]s on sight; the reason given for this is that purple worms enjoy eating shriekers. {{refsrc|src/mon.c|1391|version=NetHack 3.6.0}} 1/13 of the monsters a shrieker summons with its shriek are purple worms; this can rarely cause a purple worm to appear very early in the dungeon.

A '''purple worm''', {{monsym|purple worm}}, is a type of [[monster]] in that appears in ''[[NetHack]]''. It is a [[slithy]], [[carnivorous]] and [[oviparous]] [[animal]] that has a bite attack, as well as an [[engulfing]] attack that can potentially [[digest]] [[you]] and will also instantly kill monsters that are [[large]] in size or smaller.

==Strategy==
 +
Purple worms are both fearsome enemies and popular [[pet]]s due to their digestion attack. Though they are slow at 9 [[speed]], hostile purple worms are usually the strongest and fastest monsters with digestion attacks that you will encounter, requiring you to dispatch them quickly. If you see a purple worm approaching, you can use your best ranged attacks to kill or weaken it before it can engulf you. A purple worm's [[Magic resistance (monster)|MR score]] of 20 is not too impressive, but can be enough to make some spell-based approaches less than completely reliable.
 +
 
 +
One of the most common means of escaping the stomach of a purple worm is to zap a [[wand of digging]]: this reduces its health to 1 and forces you out, allowing you to kill it easily. A [[footrice]] [[corpse]] or [[egg]] can also turn the purple worm to stone, and will free you if done while being digested. Wearing a [[ring of slow digestion]] will prevent a purple worm from engulfing you in the first place. [[Conflict]] can be used to turn the worm against other hostile monsters and get rid of them instantly, including higher-level monsters that can generate purple worms by casting summon nasties.
 +
 
 +
===Purple worms and pets===
 +
As the purple worm's digestion attack can instakill monsters, avoid leaving pets around purple worms if at all possible ''unless'' they are too large in size to be digested. Even [[Archon]]s and other common powerful pet choices can be killed easily if a purple worm lands a digestion attack on them. While this does not apply to a [[steed]] you are currently riding, a purple worm that engulfs you while riding will force you to dismount, leaving your pet vulnerable if you are spit out quickly (usually due to slow digestion).
 +
 
 +
===Purple worms as pets===
 +
Purple worms' digestion attacks also make them powerful pets in their own right, for the same reasons that make them threats to your other pets. A purple worm can be raised to a monster level beyond its normal maximum by engulfing [[wraiths]] or eating wraith corpses, allowing them to target and engulf monsters they would ordinarily not attack; a similar effect can be produced using a source of conflict, though this comes with the risk of being eaten by the worm yourself.
 +
 
 +
Unfortunately, they are extremely vulnerable to [[shapeshifter]]s such as [[chameleon]]s and [[doppelganger]]s: engulfing them alive or eating their corpse will polymorph the worm, unless you are wearing a [[ring of protection from shape changers]].
 +
 
 +
Purple worms are also susceptible to [[green slime]]s, who can turn them into more green slimes by touching them, or else by being engulfed and digested. In addition, purple worms will often have some trouble dealing with monsters too big to engulf, such as [[giant]]s, [[ettin]]s and their [[undead]] forms.

 +
===Polymorph===
 +
Polymorphing yourself into a purple worm allows you to dispatch elusive and powerful enemies such as the dreaded [[arch-lich]] in a single turn, so long as you are not wearing a [[ring of slow digestion]].

From Hack for PDP-11 to [[NetHack 2.3e]], the purple worm uses the {{white|P}} glyph. In [[NetHack 3.0.0]], which introduces the baby purple worm, both monsters are moved to the {{white|w}} glyph.
Purple worms tend to be dangerous if you are unprepared. This is because the purple worm can engulf you, and as soon that happens it will start to [[digest]] you ("The purple worm digests you!"). If you are not able to kill the purple worm fast, it will kill you. To ensure survival after being engulfed, immediately zap a [[wand of digging]]. The purple worm will have its health points dropped to 1, so one hit will get rid of it. See also [[engulfing]]. If you are wielding a cockatrice or chickatrice corpse, stoning the purple worm while inside will give the message: '''"You jump through an opening in the new statue of a purple worm."'''

Be careful when leaving pets around purple worms, as they will run up to the worm and promptly be engulfed. Pets that are engulfed die instantly. This is a good way to lose a very powerful pet. This does not apply to pets that are being ridden. ''However'', if a purple worm engulfs you while you are riding, it will force you to dismount and your pet will be vulnerable. For the same reason, purple worms make powerful pets, as they can instantly kill things by engulfing them.

A purple worm, w, is a type of monster in that appears in NetHack. It is a slithy, carnivorous and oviparous animal that has a bite attack, as well as an engulfing attack that can potentially digest you and will also instantly kill monsters that are large in size or smaller.

Purple worms enjoy eating shriekers, and will attack any that they come across;[1] while polymorphed into a purple worm, you are warned of shriekers on the level.

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.

Purple worms that engulf monsters can gain intrinsics as they would from eating that monster's corpse. Baby purple worms can also sense shriekers.

Generation

Randomly-generated purple worms are always hostile. A baby purple worm can grow up into a purple worm.

In addition to random generation, a shrieker's shrieking will will summon a purple worm 113 of the time, regardless of depth. Purple worms can also be generated by the summon nasties monster spell.

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

Baby purple worms appear in place of adult purple worms when the latter would be generated out-of-depth by a shrieker.

Strategy

Purple worms are both fearsome enemies and popular pets due to their digestion attack. Though they are slow at 9 speed, hostile purple worms are usually the strongest and fastest monsters with digestion attacks that you will encounter, requiring you to dispatch them quickly. If you see a purple worm approaching, you can use your best ranged attacks to kill or weaken it before it can engulf you. A purple worm's MR score of 20 is not too impressive, but can be enough to make some spell-based approaches less than completely reliable.

One of the most common means of escaping the stomach of a purple worm is to zap a wand of digging: this reduces its health to 1 and forces you out, allowing you to kill it easily. A footrice corpse or egg can also turn the purple worm to stone, and will free you if done while being digested. Wearing a ring of slow digestion will prevent a purple worm from engulfing you in the first place. Conflict can be used to turn the worm against other hostile monsters and get rid of them instantly, including higher-level monsters that can generate purple worms by casting summon nasties.

Purple worms and pets

As the purple worm's digestion attack can instakill monsters, avoid leaving pets around purple worms if at all possible unless they are too large in size to be digested. Even Archons and other common powerful pet choices can be killed easily if a purple worm lands a digestion attack on them. While this does not apply to a steed you are currently riding, a purple worm that engulfs you while riding will force you to dismount, leaving your pet vulnerable if you are spit out quickly (usually due to slow digestion).

Purple worms as pets

Purple worms' digestion attacks also make them powerful pets in their own right, for the same reasons that make them threats to your other pets. A purple worm can be raised to a monster level beyond its normal maximum by engulfing wraiths or eating wraith corpses, allowing them to target and engulf monsters they would ordinarily not attack; a similar effect can be produced using a source of conflict, though this comes with the risk of being eaten by the worm yourself.

Unfortunately, they are extremely vulnerable to shapeshifters such as chameleons and doppelgangers: engulfing them alive or eating their corpse will polymorph the worm, unless you are wearing a ring of protection from shape changers.

Purple worms are also susceptible to green slimes, who can turn them into more green slimes by touching them, or else by being engulfed and digested. In addition, purple worms will often have some trouble dealing with monsters too big to engulf, such as giants, ettins and their undead forms.

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.

As of commit 1a2d844, digestion will not affect incorporeal monsters such as wraiths.

Pets will no longer eat shapeshifter corpses unless they are starving or on the verge of untaming.

Purple rain

Upon reaching the Astral Plane, some players reverse genocide purple worms, then tame them or activate a source of conflict, and finally break a wand of teleportation to warp them around the Plane in order to thin the hordes standing between them and the high altars - this is known informally as "purple rain".

Polymorph

Polymorphing yourself into a purple worm allows you to dispatch elusive and powerful enemies such as the dreaded arch-lich in a single turn, so long as you are not wearing a ring of slow digestion. However, a lack of limbs can impede prolonged progress in this state, and you must take special care not to swallow deadly prey such as cockatrices. Engulfing a wraith while polymorphed does not increase your experience level as with pets.

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 hero may get the normal secondary effects from eating a corpse, including intrinsics and/or level gain from wraith corpses, from using a polyself with a digestion attack to swallow a monster whole.

History

The purple worm first appears in Hack for PDP-11, a variant of Jay Fenlason's Hack, and is included in the initial bestiary for Hack 1.0.

From Hack for PDP-11 to NetHack 2.3e, the purple worm uses the P glyph. In NetHack 3.0.0, which introduces the baby purple worm, both monsters are moved to the w glyph.

Variants

SLASH'EM

In SLASH'EM, purple worms hit as a +1 weapon.

dNetHack

In dNetHack, a purple worm may be one of the monsters generated within a magic item vault.

110 of the monsters randomly generated on the Nightmare Temple levels of the Chaos Temple Quest will be purple worms.

FIQHack

In FIQHack, purple worms will grudge shriekers and attack them on sight.

EvilHack

In EvilHack, player monsters on the Astral Plane are given a ring of slow digestion in order to weaken "purple rain" and other similar strategies for trivializing the level.

Encyclopedia entry

A gargantuan version of the harmless rain-worm, the purple worm poses a huge threat to the ordinary adventurer. It is known to swallow whole and digest its victims within only a few minutes. These worms are always on guard, sensitive to the most minute vibrations in the earth, but may also be awakened by a remote shriek.
