Flame Wave

4th-level evocation

Casting Time: 1 action
Range: Self (40-foot cone)
Components: V, S, M (a drop of tar, pitch, or oil)
Duration: Instantaneous

A rushing burst of fire rips out from you in a rolling wave, filling a 40-foot cone. Each creature in the area must make a Dexterity saving throw. A creature takes 6d8 fire damage and is pushed 20 feet away from you on a failed save; on a successful save, the creature takes half as much damage and isn’t pushed.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d8 for each slot level above 3rd.
