A caster used this spell on up to three willing creatures to render them unconscious for a short time. The target creatures had to be within 30 feet (9.1 meters) of the caster. After the spell expired, the creatures felt slightly rejuvenated, as if they had a short nap. If the creature was disturbed or hurt during the spell's duration, the spell expired and the creature regained consciousness. A caster could target more creatures at once with this spell; the amount of creatures was determined by the caster's skill level.
