How to unlock every Shell in Mortal Shell 2
All 9 Shells, one section each: where the body lies, what is standing in front of it, and what you get once you are wearing it. 4 of them are behind a named fight; the rest are found, or handed over.
What actually unlocks a Shell?
Inhabiting one. A Shell is a body you find rather than a class you pick, so the unlock is a place you reach rather than a thing you buy. Exactly one Shell is listed as a boss drop outright; the rest are claimed where they lie, and where a fight stands in the way the source names it alongside the location.
Every line below is the catalog's. Where the source states only a place, that is all this page states: a route invented to fill the gap would send somebody the wrong way around a region for an hour.
Once you have one, the Glimpses you spend on its bond go to that Shell and no other, so committing beats sampling. The build guides name a Shell each and the Tarstones that fit alongside it.
How to unlock Eredrim the Venerable
Peace has a price.
- Where it is
- Citadel of Penance, Fainweald
- The fight in the way
- The Warden
- Named on the way
- Citadel of Penance
- Actives
- Shoulder Bash and Ethereal Diapason
- Passive
- Executioner
Both of Eredrim's actives deal Break damage and his passive pays out on Riposte, so the whole Shell is one loop: break something, riposte it, bank Slaughterer stacks, spend them before you rest. Stacks are lost on resting or being severed, which is the catch — this is a Shell that punishes retreating to a beacon, and rewards clearing a stretch in one run.
How to unlock Genessa the Wayward
Nothing is so broken it can’t be made whole again.
- Where it is
- Revenant Graves
- The fight in the way
- Sester Secundus
- Named on the way
- Marrow Keep
- Who is involved
- Sester Genessa
- Actives
- Faithful Doubles and Stray Doubles
- Passive
- Duality
Duality is the strongest passive in the game to read carefully: when her health runs out she becomes Stray instead of being severed from the Harbinger. That is a second chance built into the Shell rather than into an item. The doubles are the rest of the kit, and Stray Doubles copying sidearm attacks is what makes her the one Shell where a ranged build genuinely doubles its output.
How to unlock Gragu the Insatiable
The heart speaks no lies.
- Where it is
- One Legged Wolf Tavern
- Named on the way
- One-Legged Wolf Tavern and Temple of Vatra
- Active
- Staggering Blow
- Passive
- Revered Heart
Gragu solves sustain, which nothing else on this list does. Revered Heart restores health and refills by killing, so his healing scales with how well the fight is going rather than with a finite stock of items. Staggering Blow charges for more damage, so the Shell asks you to make room to wind up — which is exactly what a healing passive buys you.
How to unlock Harros the Vassal
A man is more than mere flesh and bone.
- Where it is
- Forlorn Village (Prologue)
- Active
- Stone Stun
The tutorial Shell, and the game takes him back — so treat him as a lesson rather than an investment. Stone Stun is the lesson: petrified enemies take no health damage but do take Break damage, which is the game teaching you that Break is the real currency of a fight before it ever asks you to manage it. It pairs directly with the Untarnished Seal you start with.
How to unlock Lazlo the Justiciar
Justice is not given, it is exacted.
- Where it is
- Royal Crypt of Mammon, Mammon
- The fight in the way
- Vellen, High Lord of Mammon
- Named on the way
- Royal Crypt of Mammon and High Lord's Keep
- Active
- Retribution
- Passive
- Fortified Plate
The only Shell with flat damage reduction — 10% while his armor is on — and the only one whose active gets stronger the more you press it. Retribution builds toward Overheat, which pays a bigger shockwave and Burn stacks at a cost. That combination makes Lazlo the most forgiving Shell to learn a hard fight on: you can afford the mistakes that teach you the moveset.
How to unlock Proxima the Broodseeker
Purpose gives the soul its shape.
- Where it is
- Fainweald
- Named on the way
- Marrow Keep
- Active
- Biosampler
- Passive
- Grafted Armor
Biosampler is a grapple, and a grapple is a movement tool as much as an attack — it pulls the enemy in or pulls you in, which is the closest thing in the game to controlling the distance of a fight. Grafted Armor's mitigation also prevents stagger, so the chance it rolls does not just cut damage, it saves your combo.
How to unlock Sariel the Endless
That path to perfection is paved with blood.
- Where it is
- Chamber of Becoming dungeon, Mammon
- The fight in the way
- Sariel, the Endless
- Named on the way
- Ruins of Mammon and Chamber of Becoming
- Active
- Exodus of Thorns
- Passive
- Purge
Sariel runs a second health bar with the sign flipped, and everything on her kit pushes it up. While she is holding no Pain, Purge turns half of an incoming hit into Pain instead, and every activation of Exodus of Thorns puts more Pain on her to spread Curse around her — so the Shell charges you in the same currency whether you are being hit or attacking. At maximum Pain you dodge faster, which is the reward for having filled it. Highest ceiling here, and the least forgiving floor.
How to unlock Smert the Apostate
Truth is the final revelation before death.
- Where it is
- Prophet's Rest, Fainweald
- Named on the way
- Fainweald
- Active
- Miracle
- Passive
- Deadly Revelation
Miracle stops time and turns you unarmed — Chaos stacks applied during the pause detonate when it resumes. Deadly Revelation only switches on at 10% health or lower. Both halves want you at the edge, which makes Smert the clearest glass cannon of the nine and the worst first pick.
How to unlock Tiel the Acolyte
Once you have nothing, you're free to take everything.
- Where it is
- Mushroom Village
- Named on the way
- Mushroom Village, Widow's Overlook and Marrow Keep
- Active
- Lingering Shadow
- Passive
- Shadow Dash
Tiel is built on one timing: Shadow Dash rewards dodging just before a hit lands, not early. Get it right and you gain Shadow and inflict Stagger damage; get it wrong and you have simply dodged. Everything else — Lingering Shadow, the Shadow Strike follow-up — spends what that timing earns, so this is the Shell that improves most as you learn the game rather than as you spend Glimpses.
Which Shell should you commit to first?
Read the passive rather than the active. It is the half that is running while you are being taken apart, and the half you are not paying for. Harros is the exception, and for a different reason: the prologue lends him and then takes him back, so nothing you spend on him stays spent.
If you would rather see the whole grid, the Shells category lists every active, passive and skill-tree node side by side.
