Lay to Rest

5th-level evocation

Casting Time: 1 action
Range: Self (15-foot-radius sphere)
Components: V, S, M (a pinch of grave dirt)
Duration: Instantaneous

A pulse of searing light rushes out from you. Each undead creature within 15 feet of you must make a Constitution saving throw. A target takes 8d6 radiant damage on a failed save, or half as much damage on a successful one.

An undead creature reduced to 0 hit points by this spell disintegrates in a burst of radiant motes, leaving anything it was wearing or carrying in the space it formerly occupied.
