The Lich is one of the most powerful undead spellcasters in the game. Like the Wight, the Lich is clad in tattered yet elaborate robes and carries a rather ornate staff, it but wears a mitre-like headdress instead of an antique crown. The Lich is also frequently in flight.
Liches are classified as Huge enemies. However, as they are capable of flying, only aerial attacks will injure them when they are in flight. They often fly to escape ground-based attacks. Nevertheless, they will lower themselves to the ground when they cast their spells.
Liches are weak to Holy-based attacks. They are also capable of inflicting the Torpor debilitation on their enemies.
