Elden Ring: How to Complete Wyndham Catacombs
On this page, we're going to reveal how to complete Wyndham Catacombs. We'll include the location, a walkthrough, and any additional information, like item drops.
Wyndham Catacombs: How to Find It
You'll locate Wyndham Catacombs southeast of Mt. Gelmir within the Wyndham Ruins. You can head north from the Site of Grace named Erdtree-Gazing Hill to make it there and then head to the highest ruined building in the area. The entrance to Wyndham Catacombs is just behind it. Just to the west of this area is a boss fight against Tibia Mariner.
Wyndham Catacombs: Walkthrough
After pushing the entrance doors open, interact with the Site of Grace just ahead to create your checkpoint. Down the stairs and just ahead of you will be the door guarding a boss fight against an Erdtree Burial Watchdog, so to unlock it, take the elevator down to your right. As you go, however, beware of the trap that shoots lightning arrows at you from behind. At the bottom will be a small pool of water with two Imps on the other side throwing lightning bombs at you. In the centre is a huge blade moving up and down that'll damage you if it catches you. Run under it carefully and kill the two Imps. Pick up the Grave Glovewort  while you're there.
In the next area will be two more Imps and a Grave Glovewort  to pick up on your left. Go down the stairs and you'll come out into a much more open area. In here, kill all the enemies and then pick up the Ghost Glovewort  in the middle.
Around the bend is a Gold Dragon Cult Knight defending a ladder, with a Grave Glovewort  off to the right. Kill it and then head up the ladder. At the top is a sealed doorway that requires a Stonesword Key. If you choose to use one here, you'll be rewarded with the Lightning Scorpion Charm. To the left is the main path, however, which is ends in a room that looks like a dead end with a spiked ceiling. The floor will begin to very quickly raise once you step out onto it, so sprint to the other side to avoid taking damage from the spikes. On the other side is an Imp to kill as well as a Gold Dragon Cult Knight. They're protecting the Lever that unlocks the boss door.
As you head back to the boss door, you'll want to mess around with the moving floor. Return to the entrance, then activate the floor and immediately roll off it. This will reveal a new area you can drop down to. Here you'll find a Magic Grease, Golden Rune , and the Ancient Dragon Apostle's Cookbook . Just watch out for the two huge Crabs that spawn here too. To get out, use the Lever on your right.
Return to the now open set of double doors the boss is behind and prepare to take on a new version of the Erdtree Burial Watchdog. This one is themed around Lightning damage, but the strategy remains the same. For much more information on this boss, click the following link: Elden Ring: How to Beat Erdtree Burial Watchdog.
