The Altar of the Accursed is a craftable post-Moon Lord furniture item. When right-clicked, it is used to summon Supreme Witch, Calamitas while Ashes of Calamity or a Ceremonial Urn is in the player's inventory. Upon successfully summoning the boss, one Ashes of Calamity is removed from the player's inventory if the player does not have a Ceremonial Urn, and the sky darkens, summoning Calamitas shortly after.

The Altar of the Accursed also serves as a crafting station to craft the Sacrilegious furniture set, and the Ceremonial Urn.
