− | + | In ''[[NetHack]]'', a '''property''' is any of several on-or-off traits of a [[monster]], including [[Hero|the player's character]]. Properties include the [[resistance]]s, the effects of [[ring]]s, the temporary effects of certain [[potion]]s, negative effects (as [[confusion]], [[stoning]]), and others. | |
− | A property is | + | A property may be '''intrinsic''' or '''extrinsic''': an "intrinsic" is any property that your character has internally, while an "extrinsic" is any property that your character derives from using, carrying or wearing an [[item]]. Intrinsic and extrinsic properties are binary - a monster either possesses a property or does not. [[Enlightenment]] will reveal many properties of the hero, along with some other traits. |
− | == | + | ==Description== |
− | + | The [[source code]] defines most of the properties in [[prop.h]] - each property has a representative integer constant. Particularly in [[objects.c]] and [[artilist.h]], the integer constants assign the properties granted by using certain [[item]]s. The integer constants also serve as array indexes into the <tt>u.uprops</tt>, an array of <tt>struct prop</tt> that records the source of each of the hero's intrinsics and extrinsics. | |
− | You gain an extrinsic when you [[wield]], [[wear]] or [[put on]] an item that provides it. The item is typically a [[ring]], [[amulet]], [[armor]] or [[artifact]]. For example, | + | While [[food appraisal]] and [[paralysis]] do not have constants in prop.h, they behave like other intrinsics, thus their inclusion in the lists on this page. |
+ | |||
+ | ===Intrinsic versus extrinsic=== | ||
+ | You gain an extrinsic property when you [[wield]], [[wear]] or [[put on]] an item that provides it. The item is typically a [[ring]], [[amulet]], [[armor]] or [[artifact]]. For example, the [[amulet of ESP]] or the [[helm of telepathy]] can grant extrinsic [[telepathy]]; the extrinsic goes away when you [[take off]] the item. Some nice [[quest artifact]]s provide an extrinsic when carried; in that case, the extrinsic goes away when you drop or lose the artifact, or place it in a container. | ||

Latest revision as of 11:19, 11 February 2024
In NetHack, a property is any of several on-or-off traits of a monster, including the player's character. Properties include the resistances, the effects of rings, the temporary effects of certain potions, negative effects (as confusion, stoning), and others.
A property may be intrinsic or extrinsic: an "intrinsic" is any property that your character has internally, while an "extrinsic" is any property that your character derives from using, carrying or wearing an item. Intrinsic and extrinsic properties are binary - a monster either possesses a property or does not. Enlightenment will reveal many properties of the hero, along with some other traits.
Contents
Description
The source code defines most of the properties in prop.h - each property has a representative integer constant. Particularly in objects.c and artilist.h, the integer constants assign the properties granted by using certain items. The integer constants also serve as array indexes into the u.uprops, an array of struct prop that records the source of each of the hero's intrinsics and extrinsics.
While food appraisal and paralysis do not have constants in prop.h, they behave like other intrinsics, thus their inclusion in the lists on this page.
Intrinsic versus extrinsic
You gain an extrinsic property when you wield, wear or put on an item that provides it. The item is typically a ring, amulet, armor or artifact. For example, the amulet of ESP or the helm of telepathy can grant extrinsic telepathy; the extrinsic goes away when you take off the item. Some nice quest artifacts provide an extrinsic when carried; in that case, the extrinsic goes away when you drop or lose the artifact, or place it in a container.
There are more ways to gain an intrinsic.
- You might gain it as an innate property of your role or race. For some innate properties, you need to first reach a certain experience level. For example, a Barbarian starts with poison resistance and gains intrinsic speed at level 7.
- You might gain it "from outside". The principal ways to do this are crowning, eating certain corpses, eating jewelry or sitting on thrones.
The gremlin has an attack that may steal one of eleven intrinsics. Also, you can lose an innate property if something drains you below the required level. Eating a disenchanter corpse may also remove one of the same intrinsics that gremlin attacks affect.
List of properties
The following tables provide a brief description of each property that the hero might have, and some notable sources of that property. (The property may have other sources.) The individual articles for each property might provide more details.
The left column also gives the associated constant from prop.h, if any. The right column may refer to a monster flag (like M1_FLY); then you may search monst.c to find a monster with that flag for polymorph.
Intrinsic properties
It is possible to receive any of these properties as intrinsics that never time out. Some are also available as extrinsics, or as temporary intrinsics. This list includes each property that may be intrinsic, even if the only way is to eat the correct ring. (Eating a ring has a chance of failing to convey the property!)
Common name of property |
Description Notable sources |
---|---|
fire resistance FIRE_RES |
Prevents fire damage, but does not fireproof your inventory.
|
cold resistance COLD_RES |
Prevents cold damage, but does not protect your potions.
|
sleep resistance SLEEP_RES |
Prevents sleep. Alternatively, free action works for potions only.

|
searching SEARCHING |
Automatically search squares around you, increasing the chance that you notice hidden doors or traps.
|
see invisible SEE_INVIS |
Allows you to see invisible monsters (and in SLASH'EM, invisible objects).
|
invisible INVIS |

Intrinsic speed makes you fast, allowing four moves for every three turns.
Extrinsic speed, and temporary intrinsic speed, make you very fast, allowing five moves every three turns.

Extrinsic properties
There are no sources that provide any of these properties as an intrinsic (without polymorphing), but they have extrinsic sources:
Common name of property |
Description Notable sources |
---|---|
acid resistance ACID_RES |
Prevents acid damage (from yellow dragon breath, or from eating acidic corpses), but does not rustproof your armor.
|
stoning resistance STONE_RES |
Prevents the stoning process. This is one way to fight cockatrices and chickatrices.
|
sliming resistance | Provides immunity to the sliming process; this protects against the slime attack of the green slime.[1]
|
drain resistance DRAIN_RES |
Protects against loss of experience levels, for example from the drain life attack of monsters. Prevents instadeath from drain below level 1.
|
adornment ADORNED |
Indicates that you wear a ring of adornment (of any enchantment). This intrinsic allows an enlightenment message to be displayed.
|
reflection REFLECTING |
Bounces gaze and ray attacks away from you, so that they do not affect you.
|
life saving LIFESAVED |
When you die, the worn amulet of life saving will resurrect you.
|
magic resistance ANTIMAGIC |
Prevents damage from certain traps, from magic missile and certain other magic attacks, and rays/fingers of death, among other useful benefits.
|
phasing PASSES_WALLS |
You can walk through walls. This is useful for taking shortcuts without digging them, and fleeing from certain places. However, this property has no effect in Sokoban.
|
hallucination resistance HALLUC_RES |
Prevents the effects of hallucination.
|
fumbling FUMBLING |
Causes you to sometimes trip while walking, accidentally drop items, fall down stairs, and have other such problems.
|
water walking WWALKING |
You can cross water by walking on its surface (as an alternative to using levitation, magical breathing or swimming). If the boots are fireproof, they may also be used to cross lava.
|
displacement DISPLACED |
Produces a displaced image of you on a nearby square, such that monsters sometimes attack the image and miss you.
|
clairvoyance CLAIRVOYANT |
Every few turns, the map of the area around you appears in your mind. This helps explore new areas and discover hidden paths.
|
energy regeneration ENERGY_REGENERATION |
Your power increases toward maximum at a much faster rate, allowing you to frequently cast spells (if you have enough nutrition). |
half spell damage HALF_SPDAM |
|
half physical damage HALF_PHDAM |
|
sickness resistance SICK_RES |
Provides complete immunity to sickness--both illness and food poisoning. |
free action FREE_ACTION |
Prevents paralysis in most cases. Makes the potion of sleeping harmless, but does not prevent other forms of sleep. Reduces stunning from monster spells to one turn.
|
swimming SWIMMING |
Enables you to swim across water. This differs from levitation (to float across water) and breathless (to go underwater).
|
sustain ability FIXED_ABIL |
Prevents changes to your six attributes. Prevents the effects of exercise and abuse.
|
flying FLYING |
Enables you to fly above the ground. Flight is better than levitation, because you may reach the ground and fly down stairs.
|
unchanging UNCHANGING |
Holds you to your current form. Use this to prevent unwanted polymorph, or to remain forever in your polymorphed form.
|
slow digestion SLOW_DIGESTION |
Decreases the rate that you lose nutrition, allowing you to survive longer before starvation. Also prevents purple worms from digesting you.
|
warned of monster type WARN_OF_MON, WARN_UNDEAD |
Detects all monsters on the dungeon level that match certain monster types.
|
Intrinsics that always time out
You may receive any of these properties in this table as a temporary intrinsic, but not as a permanent intrinsic. After a specific number of turns, you lose the temporary intrinsic. That may be well, because most of these properties have bad effects; you would want them to wear off over time.
Common name of property |
Description Notable sources |
---|---|
stun STUNNED |
Movement commands may cause you to step in a random direction, and you may hit pets by mistake. Direction of Zapping, spellcasting and firing also has a high chance of being randomized. Prevents teleport control.
|
confusion CONFUSION |
Among other effects, you will mispronounce any scroll that you read (causing the scroll to have an alternate effect), and you will have trouble with spells and spellbooks.
|
blindness BLINDED |
Disables your eyes, blocking your sight (unless you wear the Eyes of the Overworld). Intrinsic blindness will heal eventually, or you may use a cure such as a carrot.
The only cure for extrinsic blindness is to remove whatever is blocking your eyes. Cream pie will eventually fall off and can also by removed by the #wipe command. |
restful sleep SLEEPING |
You keep falling asleep.
|
paralysis | You become immobile and miss a number of turns.
|
wounded legs WOUNDED_LEGS |
Among other effects, you can carry less weight, and you cannot jump or kick.
|
hallucination HALLUC |
Gives a random appearance to any monster or object on the map, so that you do not know who or what you see. In SLASH'EM, hallucination also distorts the view of objects on the same square as you, including your inventory.
|
slippery fingers GLIB |
Causes wielded objects to drop from your grasp.
|
invulnerability INVULNERABLE |
Blocks all damage and prevents most causes of death.
|
monster detection DETECT_MONSTERS |
Detect all monsters on the dungeon level. This property is only available as a temporary intrinsic.
|
Intrinsics that cause harm on time out
These temporary intrinsics do not only time out and go away, they also cause do something (typically to cause instadeath) when they time out. When you have one of these properties, you only have some number of turns to remove the property and avoid its time-out effect.
Common name of property |
Description Notable sources |
---|---|
sickness SICK |
A fatal illness; you must cure this or it becomes an instadeath.
|
stoning STONED |
Gradual stiffening will turn you into a statue (causing instadeath).
|
nausea/vomiting VOMITING |
Can cause stun and confusion; when nausea times out, you spew part of your food and lose some nutrition.[3]
|
strangulation STRANGLED |
Your amulet will strangle you to instadeath in five turns, unless you can somehow remove it before then.
|
slime SLIMED |
Green slime will overtake your body and kill you, unless you can somehow remove the slime or gain sliming resistance before that happens.
|
Commentary
The adjective intrinsic refers to something that is internal, inherit, within the body. We also use the term as a noun. The antonym of intrinsic is extrinsic.
Oddly, sometimes we also use the term "intrinsic" to refer to any property, whether that property is intrinsic or extrinsic. For example, we might refer to an "intrinsic" from a ring, though the ring is external to the character. This leads to oxymoronic phrases such as "extrinsic intrinsic".
The usage of "intrinsic" to mean "extrinsic" occurs in other pages on this wiki, and even within the source code of NetHack. For example, the comment at the top of wield.c refers to wielded weapons conveying intrinsics, though they would actually convey extrinsics. The set_artifact_intrinsic function in artifact.c is another example of this usage. The mintrinsics field of struct monst stores information about both intrinsic and extrinsic resistances of the monsters.[4]
The struct prop that tracks properties has only separated "intrinsic" and "extrinsic" since NetHack 3.3.0.[5]
One can justify the use of "intrinsic" to mean "extrinsic". For example, an amulet versus poison may be extrinsic to your body, but when you wear it, the effect spreads inside your body and becomes intrinsic. When you eat that kobold shaman corpse, or land on poison in a spiked pit, then the poison enters your body but has no effect. There must be some intrinsic defense in your body that stops the poison, though the ring remains outside on your finger. This explanation would not work so well for an amulet of reflection.
If you quaff a potion that provides a property, it is an intrinsic or extrinsic property? One argument states that the contents of the potion enters your body, so the property must be intrinsic. (A look at struct prop supports that argument.) The other argument states any property from an item, including a potion, is an extrinsic. The potion of blindness seems to grant intrinsic blindness (not extrinsic blindness, which you could #wipe away), but the potion of speed seems to grant extrinsic speed, equivalent with speed boots.
If you acquire a property through polymorph, it is an intrinsic or extrinsic property? One argument notes that the property is intrinsic to your current form; the other argument provides that your current form is extrinsic to your true form.
