Burn Up

You use up all the fire energy you have to inflict massive damage in a 15 foot radius, centered on you. Creatures within the area must make a DEX save against your Move DC. On a failure, the creature take 5d4 + MOVE fire damage and become burned. On a success, they take half as much damage without being burned. After using this move, the user burns itself out and loses its fire-typing for the remainder of combat. Dual-type fire Pokémon change to their single other type, and single-type Pokémon become typeless, losing STAB and all vulnerabilites, resistances, and immunities.

At Higher Levels: The damage dice roll for this move changes to 3d10 at level 5, 5d8 at level 10, and 8d8 at level 17.
