The Foundry

Follow the objective marker to the gatekeeper, who will recreate the bridge to The Foundry. Karn will join you.

Cross the bridge and enter The Foundry.

In the first room with moving cauldrons, shoot the stone on the fourth cauldron to get a Stone of Resistance.

Drop into the water on the left for a chest, then climb back up and go through the next door.

On the circular platform, interact with Karn to be tossed across a gap.

Climb the wall using blocks and handholds, go around the corner, and drop onto a beam.

Wait for hanging pots to pass and jump across to them. Shimmy right and jump to the far platform when safe. Wall run across the gap.

Follow the passage, deal with tainted constructs, and reach a lever. Wall run to a nearby platform for a chest to the left of the lever.

Pull the lever to unlock the door and proceed.

Enter the next room; the door locks behind you. A portcullis opens to the left of a skull door.

Wall run up and hang on the golden lever on the wall to open the door for Karn.

Follow Karn through the next door he holds open.

Climb the stairs to see the guardian and learn you need 3 heart stones to activate it.

Go back to the entrance door and enter the door to its right. Kill the tainted golems inside.

At the intersection, continue right into the next large room.

Go to the far Eastern side, where Karn will toss you onto a gate.

Continue around the top of the wall and open the chest on the far side.

Drop down into the room below and into the central pool. Underwater, you will see an inactive golem.

In the right-hand corner from where you entered, find a Boatman’s Coin and an area to surface.

Wall run up and grab the ledge to climb out of the water.

Head out the opening on the opposite side of the room and down into the water. Dive and find the tunnel leading left. Surface and climb the wall to find a chest.

Return to the water and follow the passage to the end. Climb the wall and step on the pressure plate to lower the portcullis and open the gate to the main room.

Karn will hold the gate open. Drop down, grab the ball, and wheel it into the main room.

Place the ball in front of the ramp at the southernmost part of the room and punch it up into the slot at the top. This raises the central platform and reveals the golem.

Activate the golem. Constructs will spawn and attack; use the golem to defeat them.

Head to the North East corner of the room and have the golem use its arms to destroy the yellow crystal on the ledge above.

Wall run up and grab the chest in this area.

Backtrack through the tunnel, destroying crystals with the golem as you go. Check the alcove behind the first set of crystals on the right for a chest.

Continue through the passage until you reach the room with the skull door.

Have the golem go straight across the room and down the large open hallway. At the end, plant it in the socket and shoot the target on the opposite side of the gap.

Climb on the chain. Halfway across, look left to see a wall vine. Climb it and use the poles at the top to reach the platform at the north of the room. Enter the door.

Wall run across to the handholds on the far side. Time your wall run to avoid streams of molten rock.

Once safely across, head through the door. Fight off a group of tainted constructs, then a tainted construct champion.

Exit through the opposite door and open the chest for a skeleton key.

Drop down to the chain below. Continue back past the golem to the main room and use the skeleton key to open the locked door.

Open the door and climb the spiral stairway to the top. Enter the door.

Approach the cliff, and Karn will toss you to the other side. Fight off tainted constructs and drop to the ledge on the right for a chest.
