Enflamed Skull

"“Explosions bloom behind your eyes as you feel the blood inside your head begin to boil. Your skull elongates and expands, shearing easily through your brittle, blackened skin to form its new nightmarish structure. The burning feeling recedes, and yet you find yourself yearning for the kiss of fire to return. As though it feeds you.” —In-game description"
