Death’s Door Shrine Locations
Inner Furnace
Head down and to the right, continuing in this exact direction through a few rooms, until you reach a moving platform. Smack the arrow on the platform to move you across the gap, then take another moving platform up and to the right (you’ll need to shoot it with arrows to bring it to you). Head up the ladder, then across the pipes that go down and left. This will take you directly to the vitality crystal shrine.
Overgrown Ruins
The Hookshot is required for the third shrine.
Head through the opening in the stone wall directly behind the entrance door. Take the ladder to the left of the cave entrance in front of you, then go around the left side of the small stone enclosure ahead. Just past the crates and the small tree, take the ladder up to find the Forest People settlement. Head to the back right of the settlement and go through the gate, then up the ladder.
Follow the path up and right, then turn into the large circular stone area. Exit through the bottom of the circle, then head down and to the right to find a vine. Use it to climb up, then follow the path clockwise until you find another ladder. Climb it, then go up the vine immediately in front of you. Head to the back left of this upper platform (where the orange flower is) and you should see a break in the wall. Roll through this opening, then attack to do a ground pound to enter an underground tunnel. Follow this tunnel down and to the right until you reach the exit, then enter the door to find the vitality crystal shrine.
Backtrack to the settlement of the Forest People. Head left and walk around to the far side of the settlement, then drop off the ledge ahead of you (to the right of the tree) to a lower area. When the camera adjusts, walk up and to the left to find another magic crystal shrine.
Backtrack to the entrance of the Overgrown Ruins. Head up and left, then down and left and follow the path. When you reach a small red patch of mushrooms, turn up and to the left and walk under the wooden platform and grapple past the waterfall. Grapple twice more, then shoot the red switch in the far wall with an arrow to spawn some more walking space. Grapple up and to the left to the grass area and fight a wave of enemies. Take the vines upward and head left to find a magic crystal shrine.
