Iron Liches are enemies in Heretic. Despite their names, Iron Liches are not the typical skeleton-like foes in robes to which others may be accustomed. They are, in fact, giant skulls (not unlike the Lost Soul) wearing spiked helmets, and as the name suggests, made completely of iron, and are sometimes called Iron Golems. Iron Liches have the ability to cast three different kinds of elemental spells, all of which can inflict multiple hits and which include:
A wall of fire which spreads out vertically.
An ice ball which splits into multiple shards when it hits a target or a wall.
A tornado which relentlessly chases and throws players into the air if they get too close to it.
The Iron Lich cannot be transformed by the Morph Ovum, nor immediately killed with a Firemace under the influence of the Tome of Power. When killed, they crumble into a pile of brittle pieces on the ground, sometimes dropping a Claw Orb or Morph Ovum. With their extremely slow speed and relatively large size, the weapon of choice to kill them is the Phoenix Rod, which can dispatch a lone Iron Lich from a safe distance with five or fewer shots. In addition, the Rod's splash damage enables it to take out a group of Iron Liches with considerably less than five shots per Lich. Note that Iron Liches take half damage from the powered up Dragon Claw, though not from the rippers it shoots out. Each Iron Lich possesses 700 hit points.
