Drowsiness

Cantrip

This drains the target of 1 Spirit. If it drains them for more Spirit than they have, they fall asleep.

Great

This leaves the target exhausted for a number of turns equal to your Magic Power. You may instead incorporate the cantrip version into a weapon attack. If it hits a target who is already exhausted, they are asleep for a number of turns equal to your Magic Power.

Superior

This puts the target to sleep without requiring them to be exhausted, and lasts a number of turns equal to your Magic Power. You may extend the duration to as long as you concentrate.

Ultimate

This puts the target in an eternal slumber that lasts until extraordinary efforts are taken to break the curse. At the GM’s discretion, certain powerful enemies may take a lesser effect.
