Mortal Shell 2 Withered Shoals Walkthrough
Quick answer: Southwest Mammon Corrupted Gate, entered from the Gate of Mammon. Tag Ossinite Falls → Nameless Pass → Hexapod's Burrow. Grab Charged Stone from Odious Crevice, the Depleted Gland in the hollow arm, then jump into the void for Hexapod. Summon Proxima. Reward: Hexapod Core.

How to enter
- From Outskirts of Mammon, take the path behind the first Mammon map crow into the Abandoned Slums, then Lonesome Spire / Gate of Mammon (Fextralife progress route).
- Cleanse Gate of Mammon. That is the lock on this Corrupted Gate — not Fainweald's Nochtean Gate. One Game8 hub line mixes those names; the Shoals themselves sit behind Gate of Mammon.
- Inside: three Beacons. Activate them as you push. GamingProMax lists Ossinite Falls, Nameless Pass, and Hexapod's Burrow.
Through the Shoals
- Ossinite Falls. Game8: fight the fodder, descend the stairs, clear two Bell Snails at the gate start, loot the extra Gloom.
- Nameless Pass. Beacon here. Completing Odious Crevice rewards Charged Stone (Game8). RPS later recommends Charged on Salvaged Trebuchaxe for charge speed.
- Hexapod's Burrow. Interact with Proxima's vestige if you want the Glimpse summon. Climb the cliff / “arm.” Before the drop, enter the hollow for the Depleted Gland (healing upgrade).
- Leap into the void to start Hexapod. Do not drop until the gland is in inventory.
KeenGamer places a Strange Grisha on a Shoals island across a Bone Gate. Optional. It is not on the Hexapod critical path.
Hexapod
- GameSpot calls this the most readable of the three Mammon gate bosses. Tentacle spreads telegraph; the head is exposed.
- Squid Surge: red flash, ram. Dodge sideways, punish recovery.
- Game8: do not linger in front after a stagger — unblockable grab. Fingers all unfurled = stop attacking and dodge. Flank.
- Spirit summon: Proxima (1 Glimpse). She holds aggro while you infuse.
- Reward: Hexapod Core (Axatana ability, 60 Resolve). Achievement: Something in the deep…
Full tells: Hexapod boss page. After the cleanse you can swing back to Lonesome Spire for High Lord's Keep / Lazlo.
