Magma Storm

You stir up a maelstrom of fire in a 40 foot circle, centered on a point within range, that continues to rage as long as you hold your concentration. Any creature that enters this area for the first time on their turn, or is in that area at the beginning of their turn must make a CON save against your Move DC, taking 3d8 + MOVE fire damage on a failure, or half as much on a success.

At Higher Levels: The damage dice roll for this move changes to 5d6 at level 5, 4d12 at level 10, and 8d8 at level 17.
