Mortal Shell II: Every Playable Shell, Ability Tree, and Unlock Location
Confused about which Shell to bond first? We mapped all the playable Shells — the eight permanent bodies plus prologue-only Harros — with their full ability trees and exact unlock routes.
Mortal Shell II: Every Playable Shell, Ability Tree, and Unlock Location
Mortal Shell II hands you a roster that is best counted as eight. The official framing is “all eight playable shells” — Tiel, Proxima, Eredrim, Gragu, Smert, Lazlo, Sariel, and Genessa are your permanent bodies, each with an active ability, a passive, and an upgrade tree fed by Glimpse at Zhirelle the Shellkeeper. This guide lays out what every Shell does and where to dig it up.
About “nine”: where Harros fits (and why he leaves)
This guide’s title says nine because Harros the Vassal is technically playable — but only during the prologue. He is the body you inhabit in the opening cave and village sequence, a tutorial crutch with a Stone Stun, and the moment the intro ends he is gone permanently. You cannot recover him, and any Glimpse you sink into him before he leaves is wasted, so never treat him as a bond candidate. So: nine names, eight Shells you own. When you see other coverage say the game has eight playable Shells, that is the same fact counted from the other end. (For the eight, keep reading.)

What You Need Before Hunting the Nine Shells
- Finish the prologue. Harros is your only Shell until the opening sequence ends. Do not waste Glimpse on him.
- Reach Marrow Keep. The central hub is where Zhirelle the Shellkeeper lives. Talk to her once to unlock Glimpse spending on Shell Bonding.
- Budget your Glimpse — but stop fearing it. Launch-week math said one run covers roughly two fully upgraded Shells. The Week 1 Update (Aug 29) removed the single-run hard caps, so a full roster in one playthrough is a grind but no longer impossible, and spent Glimpses come back in full via a respec.
- Optional map markers. Pay Zhirelle 3 Glimpse per Shell for a vague zone marker; Genessa is excluded.
Where Every Shell Is Buried: Unlock Routes and Ability Trees
The table below is the at-a-glance reference. Every row is cross-checked across multiple guides.
| Shell | Active Ability | Passive | Unlock Location | Boss Kill Required? |
|---|---|---|---|---|
| Harros the Vassal | Stone Stun (petrifies nearby enemies; hardened foes take Break Damage) | None notable | Default, prologue only | No |
| Tiel the Acolyte | Lingering Shadow (invisibility + Shadow Strike) | Shadow Dash (perfect dodge grants Shadow + Stagger; undetectable while Shadowed) | Open grave, clearing SE of Widow’s Overlook, south of Mushroom Village | No |
| Proxima the Broodseeker | Biosampler (hook pull + Lightning follow-up) | Grafted Armour (15% mitigate, 50% reduction, prevents stagger) | Shattered Beacon dungeon, NE of Blackridge Pass, on a coffin | No |
| Eredrim the Venerable | Shoulder Bash + Ethereal Diapason (shockwave) | Executioner (execute low HP, Slaughterer stacks from Riposte) | Citadel of Penance, Warden boss arena | Yes (Warden) |
| Gragu the Insatiable | Staggering Blow (charged punch) | Revered Heart (heal, replenish by kills) | One-Legged Wolf Tavern -> Temple of Vatra -> Heart of Vatra | No |
| Lazlo the Justicar | Retribution (armour shockwave, Overheat = stronger + Burn, disables armour) | Fortified Plate (10% damage reduction) | Crypts of Mammon (west), after Vellen | Yes (Vellen) |
| Smert the Apostate | Miracle (time stop + Fight Stance, unarmed Chaos stacks) | Deadly Revelation (Faith at 10% HP or lower) | Outskirts of Nochte / Prophet’s Rest, Blood Offering | No |
| Sariel the Endless | Exodus of Thorns (Curse stacks, self-Pain) | Purge (no Pain -> 50% dmg becomes Pain; max Pain -> faster dodge) | SE Mammon, Chamber of Becoming after breaking 4 stones | Yes (Sariel x2) |
| Genessa the Wayward | Faithful Doubles (summon doubles, weapon attack + vanish) | Duality (becomes Stray on death instead of severed) | Marrow Keep dialogue + Abbey Entrance, Sester Secundus | No |
Tiel the Acolyte — Stealth Assassin in a Grave Southeast of Widow’s Overlook
Location: Clearing south of Mushroom Village, southeast of the Widow’s Overlook beacon. Action: Follow the downhill path, clear the cultists, pass the tree and flying enemies, enter the torch-lit doorway. Tiel is half-buried in a grave on the left. Outcome: Interact and play the memory. His invisibility has no in-game counter, making him the safest early pick and a boss-pwn machine.
Proxima the Broodseeker — Tank-and-Gold Engine Inside the Shattered Beacon
Location: Shattered Beacon dungeon, northeast of Blackridge Pass, beside the Crumbling Tunnel. Action: Enter the glowing beacon, go to the first level. Proxima lies on a coffin with no guards. Outcome: Her upgraded Biosampler harvests biosamples you sell to Merrick for Coin, the only Shell that farms currency.
Eredrim the Venerable — Boss Breaker Behind the Warden in the Citadel of Penance
Location: Citadel of Penance, via the Citadel Gate Lever or the candle teleport near One-Legged Wolf. Action: Take the lift to the central arena, interact with the coin pouch to start the Warden fight, win, loot the corpse. Outcome: A fully upgraded Shoulder Bash breaks a boss in two hits, letting you Riposte bosses on a loop.
Gragu the Insatiable — Heart of Vatra Errand
Location: One-Legged Wolf Tavern, then the Temple of Vatra east of it. Action: Exhaust Gragu’s dialogue, grab the Heart of Vatra from the temple statue, return it. He bites it and dies, leaving the Shell. Outcome: A sustain-and-burst body; strong versus bosses but clumsy versus mobs.
Smert the Apostate — Blood Offering at Prophet’s Rest
Location: Outskirts of Nochte, west of Fainweald swamps, at Prophet’s Rest. Action: Fill the three ritual pools with Blood Offerings. Each offering ejects you from your Shell and costs a health state, so recover before the next. Outcome: Smert’s body glows; claim the time-stop Shell. High risk, high reward.
Sariel the Endless — Kill Him Twice in the Chamber of Becoming
Location: SE Mammon near Silent Steps Beacon, then the Chamber of Becoming. Action: Beat Sariel above ground, follow him in, and destroy the four stone tablets before the final kill or he keeps resurrecting. Outcome: Claim the Shell and the Clockwork Scythe in one trip.
Genessa the Wayward — Censer Quest From Marrow Keep
Location: Marrow Keep (dialogue), then a red-spectre field near Abbey Entrance. Action: Exhaust Genessa’s dialogue, fight Sester Secundus via the lantern teleport, return the Sester’s Censer to her. Outcome: A summoner with a second life via Duality. Cannot be map-marked.
Lazlo the Justicar — Highest HP Behind Vellen
Location: Western Ruins of Mammon, underground cathedral. Action: Fight down to Vellen, High Lord of Mammon, win, continue to the body. Outcome: A pure tank with 10% flat reduction and AoE shockwaves.
Glimpse Economy and Other Traps Before You Commit
- The “two-Shell cap” is outdated — but the grind is not. Pre-patch guides (this one included at launch) said a first run only funds two fully bonded Shells. The Week 1 Update (Aug 29) removed the single-playthrough Glimpse hard caps and adjusted reward tables, so bonding all eight in one run is now reachable. It is still the same long collection route — the ceiling moved, not the workload. And if you bond the wrong body first, buy a Mether’s Severance from Merrick and let Zhirelle refund every Glimpse; see the respec guide.
- Map markers are vague. Zhirelle’s 3-Glimpse marker is a zone, not a pin. Genessa is unmarkable, so learn her route.
Shellkeeper Rewards and What Each Body Actually Unlocks
| Source | Reward |
|---|---|
| Zhirelle (Marrow Keep) | Shell Bonding upgrades via Glimpse; rough map markers for 3 Glimpse |
| Tiel | Stealth kit, no enemy counter to invisibility |
| Proxima | Biosample gold farm (sell to Merrick) |
| Eredrim | Boss Riposte loop |
| Sariel | Clockwork Scythe (also drops here) |
| Genessa | Duality second life |
Frequently Asked Questions
How many Shells are there in Mortal Shell II?
Nine names appear in this guide, but the official framing is 'all eight playable shells' — Tiel, Proxima, Eredrim, Gragu, Smert, Lazlo, Sariel, and Genessa are your permanent roster. The ninth, Harros the Vassal, is only usable during the prologue and is gone for good once the game opens up. This guide's headline '9' counts him; the playable count is eight.
Which Shell should I upgrade first?
Tiel and Proxima are both reachable within minutes of the prologue and cover stealth and tank playstyles. As of the Week 1 Update (Aug 29) the single-run hard caps on Glimpses are gone, so you can eventually bond every Shell in one playthrough — and a Mether's Severance reset at Zhirelle refunds Glimpses in full, so an early pick is no longer a permanent bet.
Do I need to beat a boss for every Shell?
No. Most Shells are free pickups. Only Eredrim (defeat the Warden) and Sariel (defeat him twice, breaking the stones) require a boss kill to claim the corpse.
Can I pin every Shell on the map?
Zhirelle the Shellkeeper can mark a Shell's general area for 3 Glimpse, but the marker is a vague zone, not a precise pin. Genessa cannot be marked on the map at all.
