Enkai

Starting at 3rd level, you tap into what drives your Fire Bending to increase the amount of damage you deal. You have two uses of Enkai. You regain all your expended uses of Enkai when you finish a short or long rest. You can use Enkai when you are about to throw damage for one of your fire bender spells. When you use Enkai, you increase a number (up to your Fire Bender Level) of damage die that you use by one size (d4 to d6, d6 to d8, d8 to d10, and d10 to d12. You can't go beyond a d12). You must decide before you roll for damage if you want to use Enkai or not. For example, if you use Enkai when you use fire bolt, which deals 1d10 fire damage, you would instead deal 1d12 fire damage. You gain another use at 7th level and one more at 15th level.
