Sleep

Version 0.33: This article is up to date for the latest stable release of Dungeon Crawl Stone Soup.

Puts a targeted creature to sleep. Taking damage will typically wake the target, and loud sounds can potentially do so as well.

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 0, 2 + size_factor for players, and set to 0 EV for monsters.
• SH is set to 0.
• Players take 2.5x damage in melee.
• Monsters are vulnerable to high-tier stabs from the player, and take 2.5x damage from other monsters' melee attacks.

Both players and monsters will wake up after taking any amount of damage.

Naturally sleeping monsters can wake up if you fail a stealth check, or if they hear a noise. When a monster is put to sleep by an effect, it will have a set duration, during which it can only wake up by taking damage.

Sleepwalking

Monsters that are asleep and confused at the same time will exhibit sleepwalking. They are vulnerable to high-tier stabs, but wander around as if they were confused. They can wake up, as with the normal sleep condition, though this doesn't end the confusion status.

Usually, this requires the monster to be confused, then put to sleep, since most ways of confusion will wake a monster up. The spell Alistair's Intoxication can confuse sleeping monsters, however.

Immunity

After waking from sleep, players gain stun immunity for 3-5 turns, which grants sleep immunity. Stun immunity can be gained after a few other statuses. Monsters also get a short immunity to sleep after waking.

Undead, nonliving, and plant creatures cannot be put to sleep. Of the player species, Revenant, Poltergeist, Mummy, Gargoyle, and Djinni are immune to sleep. Also, any form that would make you undead/nonlving/plant, such as Vampire Form, Statue Form, or Tree Form, will also be immune. Note: monsters of those types can still generate "dormant", which is functionally identical.

Players with clarity and all creatures under berserk are immune to sleep.

Sources

Other than the Sleep spell, the sleep status 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 0.33, Tree Form and Fungus Form did not grant immunity to sleep. When a monster was put to sleep, it could still wake from stealth or noise. Also, waking up from sleep did not grant stun immunity, only an immunity to being slept again.
• 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.
