6th-level Spell: Final Flame

High Magic (Evocation)

You place an ember of divine flame within a creature, which lies dormant until it is triggered, either by the creature carrying as a bonus action, or automatically if that creature is reduced to zero hit points.
When the flame is activated, it explodes outward, causing all creatures within 20 feet to make a Dexterity saving throw. On a failure, they take 8d6 radiant damage. On a success, they take half as much damage. The creature that triggered the flame then regains 8d6 hit points.
