Kasha's Death Rites

4th-level evocation

Casting Time: 1 action

Range: 120 feet

Components: V, S, M (a pinch of powdered bone)

Duration: Instantaneous

You conjure a 10-foot-radius pillar of ghostly flame at a point you can see within range. Creatures within the area must make a Dexterity saving throw, taking 6d6 fire and necrotic damage on a failed save or half as much on a successful one. The flames persist until the start of your next turn, shedding bright light and causing disadvantage on Wisdom (Perception) checks made to see through it.
