Sealed Tunnel Location: How to Find It

The entrance to the Sealed Tunnel is southeast of Outer Wall Phantom Tree at the bottom of the depressed lakebed. To get there, head due east from the Outer Wall Phantom Tree where you’ll find some sloped slabs of rock that can be scaled downward. From the bottom, it’s a straight shot across the body of water and into the tunnel’s entryway.

Sealed Tunnel: Walkthrough

Upon reaching the Site of Grace at the beginning of the Sealed Tunnel, you’ll likely notice there isn’t any clear path forward, but it’s just a ruse. To the west is a wall fragment between the Summoning Pool and fire fixture that you can hit to reveal an Illusory Wall behind which is the actual tunnel. Enter through to begin your journey.

Immediately on your right is a miner we’d recommend dealing with before it causes too much trouble. With it gone, continue along the left wall, roll through some wooden debris, and deal with a Vulgar Militia enemy around the left corner that’s waiting for your arrival. Afterwards, head back to the right where you’ll find a treasure chest containing the Smithing-Stone Miner’s Bell Bearing [2]. Grab some Cracked Crystals from an ore patch here before backtracking back up the slope and hugging the bend on the right to circle around some stairs where you’ll find a Golden Rune [5].

Next up is the main floor. Go ahead and drop down but be careful of the roaming miner that wields a flamethrower – make sure to defeat it first thing. Turn around after you do to find another miner defending a glowing Smithing Stone [5] at the dark dead end. Whip back around and drop down to the south where there are three miners occupied by more Cracked Crystal ore veins. Grab them if you wish, then head back to the chest we opened earlier and roll into the wall right behind it to reveal another Illusory Wall concealing the way forward.

Follow the passageway to find a lift at the end, and keep your eyes trained on the southern corner to spot a glowing Smithing Stone on your way down. It’s a little tricky to reach courtesy of the tree root jutting out right above it, but you can take as many attempts as you need jumping off the lift if you’d like another Smithing Stone [5]. If you do grab the Smithing Stone, carefully time your jumps onto the platforms leading back down to the bottom of the lift. The path ahead is concealed by yet another Illusory Wall past the tree roots that obscure the next passage.

Remove the Illusory Wall and descend the next sloped path where you can grab a Golden Rune [5] and roll into the dead end to reveal yet another Illusory Wall. Our first destination in this room is the wooden balcony along the southern cave wall. To reach it, balance along the first branch, drop down to the second one, and finally drop onto the rickety wood below. Look out for the three Vulgar Militia enemies here – one of which is right where you drop down and the two others are inside the passage. Eliminate them and follow the hallway to a dead end where you’ll get a Stonesword Key.

To continue, drop onto the branch beneath the wooden balcony, grab the Gold-Pickled Fowl Foot from the hanging corpse, and reach the next wooden platform where you’ll encounter two more Vulgar Militia foes. You can head into the next doorway if you wish, but there are a few more items down below. Heal up and get ready for a fight before dropping down. Find and eliminate the sole Vulgar Militia soldier down here to free yourself up to take on the Abductor one-on-one.

Before killing the Abductor, lure it toward the glowing statue in the eastern corner to cause the statue to split and reveal a Smithing Stone [6]. Once you’ve finished dealing with the Abductor, explore the rest of this room to find a Furlcalling Finger Remedy, a Golden Rune [1], a valuable Rune Arc, and a Somber Smithing Stone [5] tucked away in the northwestern corner. After stuffing your pockets, climb the ladder up and follow the branches across to the eastern passage.

Follow the path along until you hit a Stake of Marika and some roots blocking the path forward. Luckily, there’s an opening in the wooden platform off on the right that you can drop into to bypass the root roadblock. Once you do drop down, be ready to immediately roll away as there are a couple of exploding ruin enemies down here. Once you’re in the clear, grab another Smithing Stone [5] off the wall behind the tree root before continuing along beneath the wooden floorboards and near the steps to snag a Grace Mimic from the corpse.

Now, head up the wooden steps and coax the exploding enemies here to self-destruct, opening up the path up the next set of stairs where some Old Fangs can be found. Head back down the first flight of stairs and look off to the left to see a glowing item behind a wooden wheelbarrow. Be mindful of another salvo of exploding enemies to get to the corpse that’s holding some Large Glintstone Scraps.

We’ve finally reached the home stretch. After snagging those Glintstone Scraps, uncover the next passageway by hitting the large wall on the southeast end of this chamber, directly across from the wooden steps. Head through to reach an illuminated area with a chasm that has roots to drop down onto. Drop off of the first root to find a glowing Smithing Stone [5], jump across to the adjacent root, and do a running jump across to the other wall to reach a corpse holding a few Lightning Greases. Carefully jump across to the root and drop down the rest of the way.

Before exiting this chamber, turn around to find a few more self-destructing enemies that defend a Golden Rune [9]. Once you’ve grabbed it, you’re free to head south and up to the stone archway. Despite how suspicious it might look, the dark chamber off to the right doesn’t contain any secrets. That being the case, all that’s left is to get yourself prepped and ready before stepping through the archway and facing Onyx Lord.
