Breath of Life

You exhale a gust of positive energy in a 30-foot cone. Creatures you choose in the area regain 7d6 hit points. A creature targeted by this spell that has 0 hit points instead regains hit points equal to half their hit point maximum.

Undead in the area of the spell must make a Constitution saving throw, taking 12d6 radiant damage on a failed save or half as much on a successful one. An undead creature killed by this spell cannot be regenerated or reanimated by any means short of a wish spell.
