Once you’re at the top, you’ll notice a strange device in the middle of the room. If you look around, you’ll see there are three pressure plates around it. When you stand on all three, they’ll glow, and the mechanism will start turning. It’ll also start spawning enemies. You’ll get a unique debuff with a timer – once the time runs out, you’ll be wiped.
Start killing the enemies one by one, and at some point, an Eye of Riven elite will appear. Killing it will reward you with a Taken Essence orb, the one used to transform you into a Taken warrior. You’ll need to use it to cleanse the plates you previously stood on.
However, the puzzle will also spawn Might of Riven, extra strong Taken knights, who will charge for the plates and try to overload them, wiping your team in the process. It’s imperative you kill each knight before they get a chance to slam the plate with their sword.
If you look at the device while standing on the plates, you’ll notice symbols appearing on it. You need to discuss these symbols with your teammates. Call out your middle symbol – one of the others standing on plates will tell you they have it. If it’s on the left for them, you need to cleanse it with the Penumbra buff. It’s it’s on the right, it’s the Anthumbra buff. This way, you’ll discover which buff you need to cleanse which plate. When one player grabs the Taken Essence, the rest need to guide them towards the correct plate, depending on the buff they’ve received.
The players that stay near the device will also have to tell the one going for the orb which tunnel to take in order to get out of the now locked room. Once you’ve cleared all three plates, the timer will reset, and you’ll need to do it two more times.
