Befouled Altar is a fight in which the player fights waves of enemies. There are two located in The Forgotten Commune that can be defeated for each Scythe Hilt and Scythe Blade. These two items can be combined into the Ritualist Scythe. After destroying both altars, Elowen—the Dran at the center of the Commune—will turn into the Cursed Wretch Aberration.
The altars are stationary and have no direct defenses. Instead, they summon three waves of enemies: at the beginning of the fight, at 66%, and at 33% health. Generally only three enemies of a wave will be active at ones, with ones killed summoning the next.
