Hellstaff

The Hellstaff is a weapon in Heretic. It appears to be made out of a demon's skull and spinal column. The Hellstaff is powered by runes and rapidly fires red energy projectiles similar to Doom's plasma gun.

When a Tome of Power is active, the Hellstaff's firing rate slows down, and it launches powerful projectiles that rain a fiery substance on the area of impact at the cost of five runes per shot. Larger foes, such as an Iron Lich are likely to get hit by more droplets than smaller foes, hence causing more damage. Though boss foes have a partial immunity to this attack reducing the damage the rain does to them by 50%.

The powered-up shots will also home in on enemies provided they are centred in the player's aim when the weapon is fired. This weapon is always effective on ghosts. Maximum capacity is 200 shots, or 400 with the Bag of Holding.
