Giants' Mountaintop Catacombs: How to Find It

From the Site of Grace called Zamor Ruins, head all the way east along the mountainous path. Start heading upwards until you pass through a gap in the cliffs ahead of you. Once you come to the narrow bridge, turn back on yourself and there'll be a path to take below you in the direction you just came, to the right of where the enemies sit. At the end of this path will be the Giants' Mountaintop Catacombs.

Giants' Mountaintop Catacombs: Walkthrough

After pushing open the set of doors, follow the path around to find a Site of Grace to set up a checkpoint. At the bottom of the staircase beyond will be three Imps guarding a Grave Glovewort [7]. Once they're dead, take the path down to the right. You'll find two more Imps down here to kill — beware of the Bleed damage they can quickly build up. At the end of the hallway, there's an elevator to take even further down into the Giants' Mountaintop Catacombs.

At the bottom, you'll find the boss door guarding the Ulcerated Tree Spirit, which we need to open using a specific Lever. For now, take the path down to your left. Down here are another three Imps, two of which will throw magic bombs at you. Once they're dead, take a second elevator down. At the bottom, you'll find one of the large Pot enemies patrolling an area. Destroy it and then take the stairs to your right.

Watch out for the trap along the corridor here! There's a well-hidden pressure plate on the ground that activates a series of arrows ahead of you that deal Frostbite damage should you step on it. Stick to the sides and then take a left and then sprint through the following room, avoiding the huge blades dropping at your feet and the exploding Pots at the end. At the top of the stairs to your left will be a corridor filled with enemies pumping out Poison, which you'll need to get around. At the very end of the corridor will be another large Pot to beat and a Grave Glovewort [7] to pick up.

It'll look like you've now stumbled upon a dead end, but return to the previous room and you'll spot an open doorway to drop down next to a corpse with some Stimulating Boluses. Drop down and on your left will be a Nascent Butterfly.

Dropping down to the floor below puts you in an area you've already explored, so where's the Lever? Return to the elevator, activate by standing on the pressure plate, but then immediately get off it. This will reveal another floor below you and a large Pot to drop down onto and kill. Go forward and around the balcony to finally find the Lever, opening the boss door to the Ulcerated Tree Spirit. On the corpse next to it will be a Golden Rune [10]. Drop down, take the elevator back up, and return to the now open boss door.
