Conjure Lava

You summon 3 5ft cubes of lava, centered on points you choose within range. Any creature in any of the lava's space must pass a Dexterity save or take 8d8 fire damage. A creature must also make the save when it moves into each of the lava spaces or ends its turn there. The lava destroys nonmagical objects in its area that aren't being worn or carried.
