Cleansing Fire

A 20-foot-radius sphere of purifying flames erupts to fill a point you can see within range. Each creature within the affected area must make a Dexterity saving throw. A target takes 4d10 fire damage on a failed save, or half as much damage on a successful one. If this spell damages a creature that is under the effect of one or more enemy spells of 3rd level or lower, all such enemy spells are dispelled. At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, it dispels any enemy spell whose level is less than or equal to the level of the spell slot you used.
