## How it works

Launches a ball of fire at 20 tiles per second that flies up to 28 tiles. It explodes when it touches an enemy or a wall, hitting everything within 1.5 tiles of the blast; at the end of its range it fizzles out without exploding. Each extra projectile flies about 9° apart from the last and rolls its own damage.
