Create or Harden Lava

You either melt earth to create lava or harden existing lava.

Create Lava. You melt up to a 10-foot cube of stone, packed dirt, or volcanic rock you can see into a lava. Each time a creature enters the area of effect or starts their turn there turn there, they must make a Dexterity saving throw, taking 2d10 fire damage on a failure and half as much on a success. Flammable objects in the area of effect that aren’t being worn or carried are immediately ignited.

Harden Lava. You harden a 10-foot cube of lava into cooled volcanic rock. Creatures submerged in the lava when the spell is cast must make a successful Constitution saving throw or be restrained.

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