Boiling Oil

You conjure a shallow, 30-foot-diameter pool of boiling oil centered on a point within range. The pool is difficult terrain, and any creature entering the pool or beginning its turn in the pool takes 3d8 fire damage and falls prone. Creatures that make a successful Dexterity saving throw take half damage and don't fall prone.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
