Sleep

Version 0.30: This article may not be up to date for the latest stable release of Crawl.

Sleep is a status effect and monster-only spell. It prevents the target from moving or attacking until woken up.

Effect

Being asleep has the following effects:

• Creatures are unable to act until woken up.
• EV is set to almost zero, 2 + size_factor, for players (plus any Repulsion Field mutation). For monsters, EV is set to 0.
• SH is set to 0.
• Monsters are vulnerable to high-tier stabs.

Both players and monsters will wake up after taking any amount of damage. Monsters can also wake up if you fail a stealth check, or they hear a noise.

Immunity

For players, you can be immune by being undead (Ghoul, Mummy, bloodless Vampire), nonliving (Gargoyle, Djinni), by having clarity, or being berserk. Undead/nonliving transformations (such as Statue Form or Storm Form) are also immune.

For monsters, undead, nonliving, plants, and berserk monsters cannot be put to sleep. They can still generate "dormant".

Monster Spell

The Sleep spell attempts to put the target to sleep. It must have line of fire, and can be resisted by willpower.

The following enemies cast Sleep:

• S Aizul
• c Satyr

The following enemies may be able to cast Sleep, depending on their spell set:

• & Pandemonium lord (3.4% chance)

Sources

Other than the spell, sleep can be inflicted by the following:

• The Ensorcelled Hibernation spell (cold resistance renders immunity).
• The Sleep attack flavour of sleepcaps.
• The Dream Dust ability of dream sheep.

Monsters are usually asleep at the time that they are generated (or "dormant", if incapable of sleep).

History

• Prior to 0.24, needles of sleeping existed.
• Prior to 0.15, monsters would tend to fall asleep if enough time has passed since they last encountered the player.
