Breath of Life

You send forth a wave of divine energy in a 20 ft. cone that heals living creatures and harms Undead. Each living creature in the cone regains 4d6 hit points. Each Undead creature in the cone must make a Constitution saving throw, taking 4d6 radiant damage on a failure, or half as much damage on a success.

Using a Higher Level Spell Slot. When you cast this spell using a spell slot of 5+, both the healing and the damage increase by 1d8 per level of spell slot above 4.
