In Cult of the Lamb, there are a range of rituals you can unlock. Some of them are dictated by the choices you make in your Doctrine – you can see all of those at that link – while others are unlocked naturally or by completing quests for NPCs.
Since you won’t see all of them in a single playthrough, we thought it’d be handy to have them all in one place so you can decide which ones to aim for or see which ones you missed.
Here are all the rituals in Cult of the Lamb. We also have a separate guide to all weapons and curses in the game.
