Exhaustive Burnout

Prerequisite(s): Spinel tiefling

Your internal flames sustain your life and can give you a burst of adrenaline when they are snuffed out.

Your Strength or Constitution score increases by 1, to a maximum of 20.

Whenever you are reduced to 0 hit points or killed while under the effects of your lord of brass feature, you are instead reduced to a number of hit points equal to one of your hit dice plus your Constitution modifier (rolling the result and expending the hit die immediately). The effects of lord of brass then end immediately. If you were higher than 10 feet from the ground when this effect was triggered, your wings remain briefly. You safely descend up to 60 feet before your wings of flame vanish, provoking no opportunity attacks as you do.
