Sleep is an affliction; a negative status effect that handicaps the target.

A creature under the effect of Sleep is unable to move or take any action while they are asleep. They also can't dodge or parry any physical attacks directed at them while asleep. However, if they take any damage at all while asleep, the Sleep effect will instantly end.

Players are able to inflict Sleep on a target using the sleep spell from the Defensive Affliction Magic skill.

Players can increase their chances of resisting a Sleep Affliction spell by wearing jewelry that raises their Forest resistance.

In addition to homin mages, kidinak are also able to cast Sleep spells.
