Mortal Shell II Dungeon Walkthrough: Routes and Loot

The direct answer

For a focused Mortal Shell II dungeon walkthrough, use the Holding Cells route. The walkthrough identifies the path to the dungeon, the dungeon start, the plate that lifts the gate, the Feeding Room Key, the Rabid Grisha Pack boss, and the exit into Citadel of Penance. This page focuses on those Holding Cells checkpoints rather than filling in routes for other dungeons.

The broader walkthrough is a hub that names the Prologue, Widow’s Overlook, Mushroom Village, Sunken Village, Flooded Village, Blackridge Cliffs, Gloomshade Grove, Holding Cells, and Citadel of Penance as the early sequence. Ruins of Nochte and Desolate Peak are useful later-region names, but this page keeps its step-by-step route focused on Holding Cells.

Reach Holding Cells

The Holding Cells video begins with a chapter called “Path to Dungeon.” It does not provide a written landmark-by-landmark route, so use the first chapter for the visual approach and treat the “Dungeon Start” chapter as the point where the interior route begins.

The broader walkthrough says Holding Cells bridges Blackridge Cliffs and Gloomshade Grove. It also says the dungeon can be accessed from either side, while its own walkthrough chooses the Blackridge side and continues all the way through. That gives you a useful orientation rule: if you arrive from the other region, you may still be at the correct dungeon, but the documented guide’s reference direction is Blackridge to Gloomshade.

Start the interior route

The video marks “Dungeon Start” at a separate checkpoint after the approach. From there, the first named objective is a plate used to lift a gate. The guide does not identify the plate’s exact room, the enemy group around it, or whether the interaction is timed, so the written instruction stops at the confirmed action rather than inventing a puzzle solution.

After the gate is lifted, the next named collectible is the Feeding Room Key. The walkthrough lists it before the boss chapter, making it the route’s useful progress marker instead of a room count or an assumed side-corridor item.

The Feeding Room Key checkpoint

The Holding Cells description says the walkthrough covers all items, including key items, the boss fight, and the exit. Its chapter list specifically labels the Feeding Room Key, so that item is part of the intended route rather than an unrelated optional pickup. The guide does not state what door the key opens, its location inside the dungeon, or whether it can be missed.

The video chapter is the best way to find the key visually. No locked door or extra reward is named, so this guide keeps the checkpoint to the key’s listed position in the sequence.

Defeat the Rabid Grisha Pack

The next major checkpoint is the Rabid Grisha Pack, explicitly labeled as the boss in the chapter list. No combat transcript or reliable moveset is documented, so this page does not invent attack phases, damage values, recommended Shells, or a weakness. Treat the fight as the dungeon’s boss checkpoint and use the combat systems you already know rather than trusting unsupported “best build” claims.

The broader walkthrough also warns that the Holding Cells boss is tricky. Treat that as a practical caution, not a numerical rating: the key and gate steps are part of the runback context before the arena.

Exit to Citadel of Penance

After the Rabid Grisha Pack chapter, the video marks “Dungeon Exit [Citadel of Penance].” The broader walkthrough describes Holding Cells as a bridge between the Blackridge Cliffs and Gloomshade Grove, while the video labels its exit specifically toward Citadel of Penance. Keep both facts because they describe different map relationships rather than forcing one into the other.

Defeating the boss is not described as automatically cleansing a Beacon, unlocking a Shell, or granting a named weapon. The route endpoint listed here is the exit toward Citadel of Penance.

The larger walkthrough order

The walkthrough hub organizes the early route as Prologue, Widow’s Overlook, Mushroom Village, Sunken Village, Flooded Village, Blackridge Cliffs, Gloomshade Grove, Holding Cells, and Citadel of Penance. It describes the Prologue as the introduction to the Harbinger and first Shell, Harros, and describes Mushroom Village as a location with quests, enemies, secrets, and a first legacy dungeon. It also identifies Blackridge Cliffs as a connector region with a Shell and a primary weapon, while Gloomshade Grove leads toward Citadel of Penance.

These region descriptions help choose the next page, but they are not a substitute for the detailed Holding Cells route. Use the linked hub for broader progression context and the Holding Cells video for the concrete checkpoints.
