This article is about the buildable dark altar. For the dark altar located in the Arceuus House, see Dark altar.

The Dark altar is built in the Achievement Gallery of a player-owned house as a place where players can switch their spellbook to the Arceuus spellbook. Other players can use the altar, provided they at least have 60% favour with Great Kourend's Arceuus House.
