Sleep

You send creatures in a 20-foot-radius sphere centered on a point within range into a magical slumber. Roll 5d8; the total is the pool of hit points of creatures this spell can affect. Starting with the creature with the lowest current hit points, each creature falls unconscious until the spell ends, the sleeper takes damage, or someone uses an action to shake or slap the sleeper awake. Subtract each creature's hit points from the total before moving to the next. Undead and creatures immune to being charmed are unaffected.
