Mortal Shell 2 Walkthrough - Part 10: Magdalena's Glade (Gloom Siphon, Merrick's Shop, Tiel's Memories)

Published Aug 29, 2026 · 3 min read

Cleanse the Beacon at Magdalena's Glade

With Magdalena dead, her arena belongs to you. Enter the beacon at its center and cleanse it. The only job inside is clearing the corruption out, nothing more demanding than that, and the payout is the biggest single Ova drop in the game so far: 26 Ova at once, against the scattered handfuls the earlier beacons paid. Fast travel back to The Marrow Keep.

The Gloom Siphon and Mether's Breath

The western room of the keep has a new resident: the Gloom Siphon, the disciples' refining device. Feed it the Ova you are carrying to cleanse them, and what slips loose is Mether's Breath. From now on every cleansed beacon offers it as an option. It carries you between beacons instantly, and it burns corruption off paths that were sealed shut, opening routes you have been walking past since the first hour.

What the Breath does not do is upgrade your shells. Shells still grow on the same currencies as before. Gloom buys levels, Shell Points from those levels buy abilities, and Glimpse buys bonds at the Shellkeeper.

Merrick's Shop

South of the Siphon a door has opened: Merrick's Quarters. Merrick does not trade on the first meeting: call on him twice and he opens for business.

His stock, beyond consumables and Foundry Stone for the forge:

  • Maps that mark where to find the weapon types you are still missing.
  • 1 Revered Gland, the remains of a sacred organ, worth one more healing charge.
  • Also 1 Legendary Tar, a root-like growth that makes each heal stronger.
  • 1 Glimpse, the shell-bond currency, for when the Shellkeeper's prices outpace your finds.
  • 2 tarstones: Acolyte's Stone and Unwieldy Stone: the charged light attack and the charged heavy attack, each costing Resolve per use.

The Slayer Seal

Walk through the shop room and step outside. On the cliff edge lies the Slayer Seal.

Tiel's Next Memories

Two more chapters of Tiel's story play out in this stretch.

Chapter 2: Ember of Rebirth

The monk Oblate takes up Tiel's treatment, and the thief acquires a keeper.

Chapter 3: Remedy

The treatment ends the way treatments tend to here. Oblate orders Tiel to kill another; Tiel instead kills Oblate.
