Unquiet Grave

Place a gold coin in the mouth of a corpse or skeleton and whisper your instructions. The next time these remains are disturbed, their spirit will return just long enough to make its old body lunge at the trespasser while screaming loud enough to be heard 100 ft away. If the trespasser is 13th level or lower, they must pass a Wisdom saving throw against your spell save DC or become frightened.

Cannot affect more than one target at a time.
