How Do Dungeons Work in Mortal Shell II?

Mortal Shell II (Cold Symmetry / Playstack, released August 20, 2026) — also written Mortal Shell 2 — sends the Harbinger through region-based zones that hold beacons and numerous dungeons, many of them optional. This Mortal Shell II dungeon guide covers how dungeons work, the named dungeons documented at launch (Shrine of Trials, Martyr's Prison, Hall of Illusions, and Thieves Retreat), what clearing them rewards, and general tips for clearing them. The current official product page lists 80+ dungeons; third-party totals differ — Gamer Guides tallies 44, Game Rant reports “more than 35”, and LDShop claims “more than 60” — so the exact count is unresolved. Release-week guides are still being expanded, so dungeon lists may change.

How Dungeons Work

Mortal Shell II's main story advances region by region — Disciple's Pass, Fainweald (spelled Faenweald by some guides), Glutted Mire, Sanguine Caverns, Prisoner's Domain, and the Outskirts of Mammon — and each region contains several dungeons alongside beacons, per Game8's walkthrough, Rock Paper Shotgun's region hub, and the official Mortal Shell II Open Beta description. The official description confirms you can “cleanse beacons, explore optional dungeons, take on hidden mini-bosses and challenges...” along the way, which makes much of the dungeon content optional side content rather than a mandatory story path. Launch-week walkthroughs such as Neoseeker's cover all dungeon locations from start to finish.

Shrine of Trials (Mushroom Village)

Shrine of Trials is a dungeon in the Mushroom Village area of Mortal Shell II. Game8's walkthrough routes players through the Mushroom Village section with this step: “Move on to the locked door just behind the cage for the Chapel Key, and then finish the Shrine of Trials dungeon to get the Axe and Dagger!” A dedicated video guide by Esoterickk also documents where the Axe and Dagger are located inside the dungeon.

Martyr's Prison

Martyr's Prison is documented as the dungeon that contains the Great Martyr's Blade weapon. GameSpot's all-bosses guide links the weapon to its dungeon reward — the Captive's Scabstone Tarstone — and Gamer Guides' 44-dungeon checklist covers the prison with per-dungeon steps including how to obtain the Great Martyr's Blade. GameSpot's guide frames these boss encounters as the payoff for clearing a dungeon's hostiles first.

Hall of Illusions

Hall of Illusions is a dungeon whose boss is Vrannic the Grand Illusionist. According to the research material's cross-checked sources — GameSpot's all-bosses guide, Gamer Guides' dungeon checklist, and Game8's walkthrough — clearing the dungeon yields three Ova (x3 Ova) after the boss fight.

Thieves Retreat

Thieves Retreat is a dungeon focused on navigation rather than straightforward combat. Game Rant's walkthrough summarizes it this way: “This dungeon is all about navigating through a ruined bridge connected by invisible floors.” Game Rant publishes a full dungeon walkthrough for Thieves Retreat with its loot list, as part of its dungeon-by-dungeon guide series.

Dungeon Rewards & Clearing Tips

Clearing dungeons in Mortal Shell II pays out Tarstones — the Great Martyr's Blade's Captive's Scabstone is one documented example — along with Glimpses and Ova, and specific dungeons hold weapons such as the Axe and Dagger (Shrine of Trials) and the Great Martyr's Blade (Martyr's Prison). General tips supported by the research: clear the hostiles in a dungeon before facing its boss (GameSpot); watch for environmental gimmicks such as the invisible-floor bridges in Thieves Retreat (Game Rant); use keys found along the route, like the Chapel Key that unlocks progression toward Shrine of Trials (Game8); and follow region-by-region walkthrough hubs from Game8 and Rock Paper Shotgun, since Neoseeker's guide covers all dungeon locations, Shells, and Tarstones. Note that guides are still being rushed out during the release week — Game8 states “We are currently rushing out guides as quickly as possible” — so dungeon lists may change.
