The First Heart Stone

Armed with the Deathgrip, you’re ready to begin your search for the first of three Heart Stones needed to awaken the Guardian. But first, backtrack to the Maker Custodian you left near the lava pit and cross its chain once more. Turn to the right as you near the end, and then jump and Deathgrip a low-hanging hoop to flip over to a chest.

Return to the Crossroad Chamber and take the west passage back to the Guardian Assembly area. (Leave the Custodian behind; he can’t follow.) Cut down the hostile constructs in the area’s lava-filled west passage, and then use the Deathgrip to collect an out-of-reach Shadowbomb from the passage’s right wall. Toss the bomb at the far switch to activate it and extend a bridge. Cross over to the far door.

Area 10: Drawbridge

Turn left as you enter this area and hop across a row of beams.

Leap from the last beam to reach a ledge with a lever. Pull it to extend one half of the central drawbridge.

Run up the south wall to reach the beam above. Jump from the beam's end. Deathgrip the overhead hoop, and swing over to some ceiling growth.

Climb north along the growth, heading toward the north lever. When you reach the end, drop down and immediately Deathgrip the hoop ahead.

Drop from the beam you land on and pull the lever below. The central bridge is now fully extended.

Scamper back up to the overhead beam, and then climb to a higher hand hold. Shimmy to the right and jump to another hand hold on the east wall.

Perform a wall-run from the end of the east hand hold to reunite with Karn on the entry ledge. Cross the bridge and proceed through the west door.

Area 11: Elevator

Pull the lever in this circular chamber to make the floor slowly lower. Enjoy the ride as you wait for the floor to stop, and then advance through the west door.

Area 12: Heart Stone Chamber

The first Heart Stone tempts you from the center of this room, but even with the Deathgrip it’s too high to reach.

Let Karn toss you over to a distant ledge, and then skip across the beams that follow to reach a hand hold on the south wall.

Wall-run to the right and fire the Deathgrip at a distant hoop to extend Death’s run to the far hand hold.

Shimmy around the corner and wall-run to another hand hold. Round another corner, and then drop down to a ledge.

Hidden Chest

Before messing with the ledge’s pressure plate, turn around and jump toward the hoop on the south wall, which you exploited during your recent wall-run. Deathgrip the hoop in midair to zip up to a high nook with a chest. Wall-run back around to the pressure plate ledge afterward.

Under Pressure

Stand on the pressure plate to lower the gate ahead. Remain on the plate and Deathgrip Karn, who quickly heaves you over to a remote ledge.

Use the Deathgrip again to swing from an overhead hoop and reach a distant hand hold.

Wall-run to the left and vault a peg. Jump the corner to continue running along the adjacent wall

Pause at the next hand hold after rounding the corner. Perform a vertical wall-run to reach another chest in a small nook.

Drop down to the hand hold again and wall-run to the left to reach a wooden wall post. Perform a 180 leap to reach the hanging post behind you.

Execute another 180 leap to reach another hanging post. Perform one last 180 leap to reach solid ground below.

Custodian Comrade

Drop down to a lower ledge, then wall-run over to the Maker Custodian that rests amongst boiling lava. Power it up and climb aboard.

Roll the Custodian south, over the shallow lava, and veer left to locate a patch of solid ground. Carefully dismount the Custodian and crack open the chest you find here.

Backtrack a bit so you that can veer right and ride the Custodian farther south. Destroy the Corruption crystals that get in your way, and then continue toward an orb slot. Park there and launch a chain at the north wall’s high target, and then tiptoe across.

Leap from the end of the chain and scale the west wall’s hand holds. Shimmy around the corner and climb up.

Have a Heart Stone

At last, you’ve reached the Foundry’s first Heart Stone. Simply use the Deathgrip to latch onto the precious object and cut it down.

Returning the First Heart Stone

Karn quickly collects the massive Heart Stone from the ground. Go east to return to the elevator and pull the lever to begin your ascent. Beware: an army of Corrupted Constructs will assault you on your way up!

Return to the Guardian Assembly area, and the Heart Stone will magically find its way onto the hulking creature. Two more to go!
