Avernus Cinderstorm
Level 18 Blaster
XP 2000

A ball of hellfire streaks down from the sky and explodes on impact, becoming a roiling, angry cloud of hot embers. This phenomenon, sometimes called battle’s bane, is rare outside Avernus, the first layer of the Nine Hells, though it occurs in other astral dominions after fevered battles.
