Foxfire Conflagration

8th-level evocation

Casting Time: 1 action

Range: 150 feet

Components: V, S, M (a fox-shaped charm)

Duration: Instantaneous

You summon a swarm of spectral foxfires to bombard a 60-foot-radius area within range. Each creature must make a Dexterity saving throw, taking 16d6 fire damage on a failed save or half as much on a successful one. The area becomes suffused with intense yokai energy, creating magical darkness for 1 minute that only you and creatures you designate can see through.
