When you were first approached by the All-Fire, you were blinded by searing light and fire on one side, and a crushing, freezing darkness. Your ears are filled with the all-encompassing noise of fire It commanded you in no uncertain terms, that you are to cleanse your planet of the dark. What it meant, you weren't entirely sure, as immediately afterwards, you were thrust back into wakefulness, with a splitting headache and the smell of ash filling your nose. 

Since then, you have been scouring the land for this darkness. Some seemed obvious: Murderers, Arsonists, and the like. However, as you continue this path, deeper darknesses reveal themselves to you. Necromancy, demon cultists, and their Ilk. But is that what it really wants?

Flash Fire

Starting at 10th level, your attunement to the firey magic your patron has given you reaches inferno levels. You can, three times a day, use this full power to double the damage of any fire damage you deal, however, you take 1d6 force damage in return.

Consume By Fire

Starting at 14th level, when you hit a creature with an attack, you can use this feature to instantly consume the target with fire.The target is engulfed in white hot fire, and it takes 10d10 fire damage damage as it is consumed by the flames. If this kills the target, they are turned to ash and cannot be resurrected by any means, except Wish. If the target survives, they ate stunned for a turn.

Once you use this feature, you can’t use it again until you finish a long rest.
