The lich is a difficult Hardmode boss, that can be summoned at night after crafting a Soul Forge and obtaining Hallowed Bars, Souls of Night and Pumpkins.

While The Lich is alive, its exclusive Music will play.

The Lich flies after nearby players, unleashing dark magical attacks, and ramming into the player for massive damage.
