Steam Blast

4th-level evocation [clockwork]

Casting Time: 1 action
Range: Self (15-foot radius)
Components: V, S, M (a tiny copper kettle or boiler)
Duration: Instantaneous

You unleash a burst of superheated steam in a 15-foot radius around you. All other creatures in the area take 5d8 fire damage, or half as much damage on a successful Dexterity saving throw. Nonmagical fires smaller than a bonfire are extinguished, and everything becomes wet.

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 4th.
