A Firestorm at the ready against a Stalker.

Firestorm is the Cleric's third weapon from Hexen. It is a spell which launches a streak of flame directly ahead of the player. If it comes into contact with a monster it will explode and spawn a small ring of flames that rotate around the point of impact, which will detonate upon contact with an obstacle or wall, heavily damaging the target and any other monsters within a short radius. Its icon is a spinning eight-pointed iron cross with a flame shooting upward. The spell uses four Green Mana per shot.
