This spell sends 3d6 hit dice creatures into a magical slumber. Creatures within 20 feet of a point you choose within range are affected in ascending order of their current hit dice (ignoring unconscious creatures). Only creatures with 4 or fewer hit dice are affected by this spell.
Among creatures with equal HD, those who are closest to the spell’s point of origin are affected first. A creature’s hit dice must be equal to or less than the remaining total for that creature to be affected.
Each creature affected by this spell falls unconscious until the spell ends, the sleeper takes damage, or someone uses an action to shake or slap the sleeper awake.
Undead and creatures immune to being charmed aren’t affected by this spell.
