A '''cloak of invisibility''' is a type of [[Magical item|magical]] [[armor]] that appears in ''[[NetHack]]''. It is a [[cloak]] that is made of [[cloth]] and has a [[randomized appearance]] when unidentified; the default one associated with it is an [[opera cloak]].{{refsrc|src/objects.c|468|version=NetHack 3.6.7}}

==Generation==
Cloaks of invisibility make up {{frac|100}} (1%) of all randomly-generated armor. General [[store]]s, used armor dealerships and antique weapons outlets can sell cloaks of invisibility.

[[Player monster]]s that are not [[Monk (player monster)|monks]], including those generated on the [[Astral Plane]], have an effective ~14.83% chance of [[Monster starting inventory|generating with]] a cloak of invisibility as their initial cloak before role-based replacements.{{refsrc|src/mplayer.c|157|version=NetHack 3.6.7}}{{refsrc|src/mplayer.c|207|version=NetHack 3.6.7}} [[Priest (player monster)|Priests]] have a {{frac|3|4}} chance of forcing a [[robe]] instead, reducing their effective chance to ~3.71%, while [[Wizard (player monster)|wizards]] have a {{frac|2}} chance of forcing a [[cloak of magic resistance]], reducing their effective chance to ~7.42%.{{refsrc|src/mplayer.c|217|version=NetHack 3.6.7}}{{refsrc|src/mplayer.c|248|version=NetHack 3.6.7}}

==Description==
While [[worn]], the cloak of invisibility grants 1 base point of [[AC]], [[invisibility]] and [[MC1]]. Wearing the cloak will [[auto-identify]] it if the wearer is not already invisible, as will [[taking off]] the cloak without any other source of invisibility active.

==Strategy==
{{main|Invisibility}}
The cloak of invisibility is often the first source of the property for many characters, and is a useful survival aid early on since monsters will take a [[to-hit]] penalty and attack squares where they believe you to be. Characters typically exchange this cloak once they find a much better cloak and/or another source of indefinite or permanent invisibility, such as a [[ring of invisibility]] or a [[wand of make invisible]].

[[Displacement]], e.g. from the [[cloak of displacement]], lacks the to-hit penalty applied for invisibility, but has better long-term applications for most characters: a particular monster has a {{frac|4}} chance of discovering a displaced character's actual location compared to {{frac|3}} for invisibility, and while many later monsters have the ability to [[see invisible]], there is no immunity to displacement and only especially fast monsters will reliably hit through it.

Avoid wearing random cloaks in shops without at least testing their [[beatitude]] - if the cloak is a cursed cloak of invisibility, the character may not be able to leave the shop without some difficulty and possibly even an angered [[shopkeeper]].

==History==
The cloak of invisibility is introduced in [[NetHack 3.0.0]]. From this version to [[NetHack 3.4.3]], including some variants based on those versions, the cloak of invisibility grants [[Magic cancellation (3.4.3)|MC2]] while worn. This is changed to MC1 in [[NetHack 3.6.0]].

==Variants==
===SLASH'EM===
In [[SLASH'EM]], the cloak of invisibility provides MC2 while worn.

Upgrading a cloak of invisibility has a {{frac|2}} chance of producing an [[elven cloak]], and upgrading an elven cloak or [[oilskin cloak]] has a {{frac|4}} chance of producing a cloak of invisibility.

A game that randomizes them to appear as an "opera cloak" will result in invisible [[Vampire (monster class)|vampires]], which are annoying if not more difficult to fight unless a character has see invisible.

===dNetHack===
In [[dNetHack]], [[notdNetHack]] and [[notnotdNetHack]], the cloak of invisibility confers 1 AC, 0 [[DR]], invisibility, and MC2 while worn.

Male [[Drow (starting race)|drow]] [[Anachrononaut]]s start with a +0 cloak of invisibility.

The Sand-walker's Shop in [[Elshava]] can sell cloaks of invisibility. Wizard driver [[Amm Kamerel]] have a {{frac|3}} chance of generating with a cloak of invisibility. One map of the [[Grue's Cavern]] has a treasure pile with a cursed -1 cloak of invisibility.

There are also artifact cloaks of invisibility as well:
* [[dNetHack artifacts#The Veil of Latona|The Veil of Latona]] is a [[neutral]] [[Intelligent artifact|intelligent]] [[artifact]] cloak of invisibility, and is the [[crowning]] gift for neutral [[Ranger]]s that are [[Human (starting race)|human]], [[Incantifier (starting race)|incantifier]] or [[Half-dragon (starting race)|half-dragon]]. While carried, it grants [[drain resistance]], and while worn it grants [[magic resistance]] and [[reflection]] in addition to invisibility.
* [[The Mantle of Heaven]] and [[The Vestment of Hell]] are artifact cloaks that always have a specific randomized appearance, making it possible for one of them to be a cloak of invisibility.

A cloak of invisibility can be used to repair the active camouflage system of [[Imperial elven armor|imperial elven body armor]], allowing it to grant invisibility while worn.

==Encyclopedia entry==
{{encyclopedia|
Cloaks are the universal outer garb of everyone who is not a Barbarian.  It is hard to see why.  They are open in front and require you at most times to use one hand to hold them shut.  On horseback they leave the shirt-sleeved arms and most of the torso exposed to wind and Weather.  The OMTs [ Official Management Terms ] for Cloaks well express their difficulties.  They are constantly _swirling and dripping_ and becoming _heavy with water_ in rainy Weather, _entangling with trees_ or _swords_, or needing to be _pulled close around her/his shivering body_.  This seems to suggest they are less than practical for anyone on an arduous Tour.
