It causes monsters without ability to see the player to have reduced chance to hit. Ranged attacks will be directed generally in player's direction, but usually not in the player's square (greatly reduces chance to be hit by a such attack). The spell will not, however, help the player to escape the attention of the monsters, as they can always see the player.
 
 
 
Invisible monsters (against a player without ability to see them) aren't shown on the map, are harder to hit and little is revealed about their state ("you hit/miss it" is the only information revealed for most attacks). Gods who appreciate killing still count invisible monsters.

=== Operation ===
+
'''Invisibility''' is a level 6 [[Hexes]] spell which fires a single-target enchantment beam, rendering the first target it strikes [[invisible]]. This generally makes the target (usually the player) harder to perceive by opponents that cannot [[see invisible]], greatly benefiting [[stealth]]y [[stabbing]]-focused characters. See the [[Invisible]] page for more details.
Casting this spell allows you to project a single-target enchantment beam; the first creature in the beam's path automatically becomes [[invisible]]. The most obvious use of this is to make ''yourself'' invisible by targeting it in direction ".". Doing so incurs 1d2 points of magic contamination.
 
  
=== Duration ===
+
This spell cannot affect targets which are [[Invisible#Backlighting|backlit]] from [[Corona]], a [[halo]] or [[glow]] from [[magical contamination]] (which includes casting the spell multiple times in succession) - casting it on yourself immediately gives you a small amount of [[magic contamination]] and then gradually more over time as you remain invisible.
For the player, Invisibility effects from whatever source have a duration of 14 + 1d(power) turns (subject to a hard cap of 100). When you become invisible, any current Backlight effect is dispelled.
 
  
== Invisibility evocation ==
+
==Strategy==
Equipping a [[ring of invisibility]], [[cloak of darkness]], [[List_of_unrands#+4_Robe_of_Night|robe of Night]] or an artifact with the Invisibility power allows you to turn Invisible with a power based on your Evocations skill. (You can also ''cancel'' invisibility from any source with 100% reliability if you have such an item equipped.)
+
The most straightforward use for Invisibility is to cast it on yourself, greatly boosting your ability to sneak up on and [[stab]] enemies incapable of detecting invisible creatures. This will generate significant amounts of magic contamination if overused, so give yourself time to decontaminate if you find yourself casting it repeatedly. Alternatively, you may wish to use the [[Dazzling Spray]] spell. This level 3 spell both damages and [[blind]]s targets, including many enemies that can [[see invisible]], providing many of the benefits of invisibility with none of the penalties.
  
The invisibility evocation has a power of ((2 * (Evocations skill)) + 5), and incurs 1d3 points of magic contamination when activated.
+
Casting Invisibility on your allies does not cause any magic contamination on your part, but provides them with little significant benefit.
  
== Wand of invisibility ==
+
Avoid remaining in water while invisible, as this will reveal your location to nearby monsters.

For the player, a wand of invisibility operates in much the same fashion as the spell (including the 1d2 contamination effect). The power of a wand of invisibility, like any other wand, is 15+2.[[Evocations]].
+
If you can cast it reliably before the [[Lair]] branches (the [[Swamp]], [[Shoals]] and [[Spider's Nest]]), it is a good investment because most monsters there do no have the [[See Invisible]] intrinsic, making them much easier to deal with. If you are a stabber it is particularly helpful. Invisibility is also useful in [[the Vaults]] and [[Elven Halls]], as even though many higher level enemies can see invisible, the weaker enemies and packs are trivialised by invisibility.
  
== Potion of invisibility ==
+
Notably in [[The Realm of Zot|Zot]], [[Draconian_(monster)|Draconians]] cannot [[see invisible]] either.
''See [[Potion of invisibility]] for the item properties.''
 
  
Like all potions, potions of invisibility operate with a fixed power rating of 40. Unlike the wand, spell, or evocation, drinking a potion of invisibility does ''not'' incur automatic magic contamination.

Invisibility applied to monsters from ''any'' source, regardless of power, has a duration of 16 to 56 of the monster's turns. Many spellcasters can cast Invisiblity.  They will generally not to do so unless you are in line of sight, so you will at least see them before they become invisible. However, the following monster are innately, permanently invisible:

There are also a few enemies which are inherently invisible and will never be seen, namely [[unseen horror]]s, [[ghost moth]]s, [[shadow wraith]]s and [[lorocyproca]]s.
  
Several things can negate invisibility.  Most notably, [[glow]] from any source, including the [[Corona]] spell, [[sticky flame]], or [[magical contamination]], will make any invisible being visible.  Also, stepping in water while not [[flying]] will cause you (or a monster) to become temporarily visible.

This page is about the Invisibility spell. For the armour ego, see Invisibility (ego).

Turns a targeted creature invisible. Turning invisible causes magical contamination and may eventually cause glowing, nullifying the invisibility.

Invisibility is a level 6 Hexes spell which fires a single-target enchantment beam, rendering the first target it strikes invisible. This generally makes the target (usually the player) harder to perceive by opponents that cannot see invisible, greatly benefiting stealthy stabbing-focused characters. See the Invisible page for more details.

This spell cannot affect targets which are backlit from Corona, a halo or glow from magical contamination (which includes casting the spell multiple times in succession) - casting it on yourself immediately gives you a small amount of magic contamination and then gradually more over time as you remain invisible.

Strategy

The most straightforward use for Invisibility is to cast it on yourself, greatly boosting your ability to sneak up on and stab enemies incapable of detecting invisible creatures. This will generate significant amounts of magic contamination if overused, so give yourself time to decontaminate if you find yourself casting it repeatedly. Alternatively, you may wish to use the Dazzling Spray spell. This level 3 spell both damages and blinds targets, including many enemies that can see invisible, providing many of the benefits of invisibility with none of the penalties.

Casting Invisibility on your allies does not cause any magic contamination on your part, but provides them with little significant benefit.

Avoid remaining in water while invisible, as this will reveal your location to nearby monsters.

If you can cast it reliably before the Lair branches (the Swamp, Shoals and Spider's Nest), it is a good investment because most monsters there do no have the See Invisible intrinsic, making them much easier to deal with. If you are a stabber it is particularly helpful. Invisibility is also useful in the Vaults and Elven Halls, as even though many higher level enemies can see invisible, the weaker enemies and packs are trivialised by invisibility.

Notably in Zot, Draconians cannot see invisible either.

Monster Version

  • Invisibility applied to monsters from any source, regardless of spell power, has a duration of 16 to 56 turns. Many enemy spellcasters can cast Invisibility.
  • Monsters will generally not do so unless you're in line of sight, so you will at least see them for a moment before they become invisible.
  • Do note that monsters also will cast it when in sight of your allies (f.e. your undead minions rushing ahead of you). This can lead to an invisible spellcaster coming right at you, without giving you any hints about its presence until the first attack starts. While this may be a niche case, it is a rather deadly and unexpected one. There are also a few enemies which are inherently invisible and will never be seen, namely unseen horrors, ghost moths, shadow wraiths and lorocyprocas.

See the Invisible page for a full list of monsters capable of casting Invisibility, as well as a list of monsters who are innately, permanently invisible.
