Version 0.30: This article may not be up to date for the latest stable release of Crawl.
Invisible is a status effect which renders the target unseen except through see invisible. It functions differently depending on whether it affects a player or a monster.
Contents
Player Version
If a monster does not have see invisible, you get the following bonuses against them:
Combat
- Attackers have their to-hit (accuracy) reduced against you, and there's a chance to target the wrong tile entirely.
- Melee to-hit is reduced by -35%. Ranged attack to-hit is reduced by -50%.
- You can make low-tier stabs. (See the Stabbing article for details)
- Enemy SH is divided by 3.
Detection
- Sleeping / wandering monsters are less likely to notice you.
- Monsters are less likely to use certain spells or abilities against you.
- Monsters don't know your exact position. See below for details.
Guessing your Position
Generally, monsters that can't see you will act like they are confused, without the chance of always moving "correctly". However, they have a chance of guessing your position:
- Seeking monsters will randomly target a nearby tile when the player is within two tiles.[1]
- Monsters have a 33% chance to guess the player's tile if the player is right next to them.[2]
- Monsters of human intelligence have an extra 8% chance to guess the player's position.
- Ashenzari penance improves the chance of guessing by 50%.
Invisibility has no effect if:
- You are in water and not flying above it.[3]
- If you are backlit (inflicted by Corona, hit by Sticky Flame, inside a halo, or if magical contamination is above 5000).
Sources
You can become invisible by:
- quaffing a potion of invisibility.
- using the Evoke Invisibility ability granted by a scarf of invisibility or certain artefacts (attempting to use this ability, succeed or fail, will drain you).
- Dithmenos' Shadow Form turns you into a shadow, granting intrinsic invisibility.
Regardless of source, player invisibility lasts for 15 + 1d(spell power) turns (max: 100 turns).[4]
Strategy
Almost every character benefits tremendously from being invisible. Many difficult enemies can not see invisible, from most monsters in the Spider's Nest, Swamp, and Shoals, to draconians and death cobs in Zot, to hellions and tormentors in extended. Ghost moths, themselves invisible, are a pertinent threat to all visible casters. Stealthy stabbers benefit most - it greatly enhances your effective stealth and your damage output in melee.
Despite the benefits, there are a few downsides to invisibility:
- The list of monsters capable of seeing invisible is unfortunately rather large (see Category:See invisible), making the status effect completely useless against them. By the time you get a reliable means of invisibility, more and more monsters won't care.
- Every method of turning invisible has its own quirks:
- Potions are reliable, but are rare and come in limited quantity.
- Evocable invisibility is a renewable source of invisibility. But finding a source isn't guaranteed. And, even with Evocations training, the drain is a very significant cost.
- Shadow Form requires significant Invocations training to be reliable, carries a significant MP and piety cost, drains you when activated, further drains you when you take damage, all the while reducing your damage output and spellpower.
As you progress, and as more monsters gain SInv), invisibility shifts from "a buff that can kill most things outright" to "a defense against common/weak monsters". Being invisible won't help one bit against an orb of fire, but it'll make nearby draconians less likely to hit you.
Tips & Tricks
- Note that monsters will remember your old position. Therefore, you should move a few tiles after becoming invisible. That way, monsters are much less likely to target the right tile.
- Dazzling Flash or a wand of light (if it has generated) replicate invisibility. These effects blind opponents; a blind opponent treats you as invisible, even if they have see invisible. However, the former can fail, and the latter has a limited number of uses.
Monster Version
Invisible monsters are very dangerous to a player who cannot see invisible. If you cannot see invisible, then in melee with invisible monsters:
- Your block rolls are divided by three.
- You suffer a -10 penalty to your EV against their melee attacks
- You suffer a -6 penalty to your melee to-hit number against invisible monsters.
On top of that, invisible monsters cannot be seen either within your line of sight or on the map, and if you actually manage to guess which tile they're in and attack them, you receive significantly less information than normal (the monster is referred to as "something" rather than by its actual name).

This effect has a finite duration, but the monster can always recast it after it has run out.
Potion users
Monsters who know how to use potions may use potions of invisibility to make themselves invisible. This effect has a finite duration, but the monster may be able to reapply the effect by quaffing another potion (if it has one).
Detecting invisible monsters
See invisible
If you have the see invisible intrinsic, invisible monsters gain no benefits against you. You can acquire this in the following ways:
- Having the Acute Vision mutation. Spriggans, vampires, nagas, felids, and palentongas all have this mutation naturally.
- Having rank 3 of the Antennae mutation. Formicids start with this, and demonspawn may develop it as they grow.
- Wearing a ring, headgear, or artefact with the see invisible ego
- Having rank 3 of Jiyva's Eyeballs mutation.
Backlighting
Under some circumstances, a target may become backlit (also known as glowing). This renders its invisibility ineffective, and actually makes it easier to hit than normal. Backlighting occurs whenever:
- An invisible target is affected by the Corona status (must overcome willpower).
- An invisible, corporeal target (i.e. one that is not insubstantial) is covered with Sticky Flames, unless it's standing in water (which immediately extinguishes the flames).
- An invisible creature enters a halo.
- The player suffers from significant amounts of magical contamination (yellow or worse).
Invisible monsters revealed as a disturbance
All invisible monsters will occasionally leave disturbances while invisible, represented by a white humanoid outline if playing in tiles or by the { glyph if playing in console. If you attack a square and the monster does not move from that square, the monster will be revealed as a disturbance until it moves (the only invisible monsters likely to shift position without you moving first are unseen horrors).
All corporeal invisible monsters create disturbances when passing through an opaque cloud (e.g. fog, steam), revealing their position (but not any further information). Do note that this only applies to monsters -- invisible players are not revealed in clouds. Anything the player can do to create clouds when an invisible creature is near will aid him in determining that creature's location:
- Reading a scroll of fog or bleeding smoke (granted to followers of Dithmenos or characters wearing the cloak of the Thief).
- Using Fire Magic in and over water, creating steam clouds.
- Using Ice Magic in and over lava, creating steam clouds.
- Invoking Wu Jian's Heavenly Storm ability.
Additionally, any invisible creature, including the player, standing or swimming (e.g. not flying) in liquid (shallow water, deep water, and lava) is always visible as a disturbance.
History
- Prior to 0.30, chaos attacks could give invisibility.
- Prior to 0.28, Invisibility was a spell available to players, which was one of the main ways of getting this status. The status would also give magic contamination over time, and many more late-game monsters had access to SInv.
- Prior to 0.27, the wand of random effects could turn you or monsters invisible. Replaced with a piece from Xom's chessboard, which only targets monsters.
- Prior to 0.26, the invisibility ego did not drain its user when used.
- Prior to 0.22, the submerging mechanic existed. Certain monsters had an ability to render themselves effectively invisible by hiding in deep water, lava, or even under the floor.
- Prior to 0.20, invisibility increased the player's hunger rate by 5.
- Prior to 0.18, invisibility reduced the combat accuracy by 5 for the player and monsters if they couldn't see invisible themselves.
- Prior to 0.16, the sense invisible intrinsic existed, which was an upgrade to see invisible.
- Prior to 0.13, invisible monsters were immune to the effects of Olgreb's Toxic Radiance.
