There’s a hallucination challenge to the southwest of the Isle of Ely Monastery, in the Grantebridgescire region in Assassin’s Creed Valhalla that could potentially stump you. The challenge features five braziers that you need to light up the correct ones. Nothing bad happens to you if you’re incorrect, but you’ll definitely feel like you’re doing something is wrong and you won’t be able to complete the challenge.
All of the flames will start as red. When you interact with them, they turn blue. You don’t have any clues about how to light them correctly or what order you need to do. The trick is to investigate the surroundings around the fire and see what stands out. When you broaden away from the inner circle, you may notice that there’s a gate behind each of the fires, but only a select few of them.
You want to light up the ones that have gates, and only those. Once you have the correct order, you’ll see a prompt click the right thumbstick down and focus. When you focus, and all you now need to do is proceed through the gate in front of you. Going through the gate completes the challenge, adding another completed mystery to your checklist.
