Suzy's Cocoa Blast

A small marshmallow flies forth from your fingertip, reaching a point within range that you select. On arrival, the marshmallow bursts with a loud pop, showering the area with flesh-searing hot chocolate. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target is scalded for 8d6 fire damage on a failed save, or half as much damage on a successful one.

The liquid spreads around corners. It flash-boils objects in the area that aren't being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
