Create or Destroy Lava

You either create or destroy lava, which lasts until the end of duration.

Create Lava. You create up to 10 gallons of lava within range in an open container. Alternatively, it spreads out in  a 30-foot diameter circle within range. Creatures stepping in the lava take 3d6 fire damage each round they are in it and have their movement speed halved. Any flammable objects not being worn or carried within that range catch on fire

Destroy Lava. You destroy up to a 30-foot cube of lava within range.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you create or destroy 10 additional gallons of lava, or the size of the cube increases by 5 feet, for each slot level above 1st.
