| − | A '''property''' is any of several on-or-off traits of the [[hero]] or a [[monster]]. 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 may be '''intrinsic''' or '''extrinsic'''.
| |
| | | | |
| − | Intrinsic and extrinsic properties are binary; you either have it or you don't. Thus numerical traits (as [[alignment record]], [[dexterity]], [[luck]], [[prayer timeout]], etc.) are not properties in this sense. [[Enlightenment]] will reveal many properties of the hero, along with some other traits.
| |
| − |
| |
| − | == Intrinsic versus extrinsic ==
| |
| − | In ''[[NetHack]]'', 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]].
| |
| − |
| |
| − | 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, 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.
| |
| − |
| |
| − | 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 [[corpse]]s, [[eating jewelry]] or sitting on [[throne]]s.
| |
| − |
| |
| − | 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 <tt>M1_FLY</tt>); 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 [[eating jewelry|eat the correct ring]]. (Eating a ring has a chance of failing to convey the property!)

| |
| − | == Commentary ==
| |
| − | The adjective [http://www.dict.org/bin/Dict?Form=Dict2&Database=*&Query=intrinsic ''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 [[artifact.c#set_artifact_intrinsic|<tt>set_artifact_intrinsic</tt> function in artifact.c]] is another example of this usage. The <tt>mintrinsics</tt> field of <tt>struct monst</tt> stores information about both intrinsic and extrinsic [[resistance]]s of the monsters.<ref>{{sourcecode|monst.h|63}}, {{sourcecode|mondata.h|14}}, {{sourcecode|mondata.c|23}}, {{sourcecode|worn.c|260}}</ref>
| |
| − |
| |
| − | The <tt>struct prop</tt> that tracks properties has only separated "intrinsic" and "extrinsic" since [[NetHack 3.3.0]].<ref>{{sourcecode|NetHack 3.2.0/you.h|108}}, {{sourcecode|NetHack 3.3.0/prop.h|78}}</ref>
| |
| − |
| |
| − | 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 <tt>struct prop</tt> 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.
| |
| − |
| |
| − | == Source code ==
| |
| − | ''For details, see [[prop.h]]''
| |
| − |
| |
| − | The [[source code]] defines most of the properties at {{sourcecode|prop.h|8}}. 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.
| |
| − |
| |
| − | 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.
