Yawn

Causes the target to fall asleep at the end of the next turn. Fails when used if the target cannot fall asleep or if it already has a non-volatile status condition. At the end of the next turn, if the target is still active, does not have a non-volatile status condition, and can fall asleep, it falls asleep. If the target becomes affected, this effect cannot be prevented by Safeguard or a substitute, or by falling asleep and waking up during the effect.
