Devilish Fury

You chant the powers of the creatures of the Nine Hells and direct that power towards a creature, engulfing them in hellish flames. The creature must make a Dexterity saving throw against your Spell Save DC. It takes 4d10 fire damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d10 for each slot level above 3rd.
