Mortal Shell II: The Fastest Grisha Remnant Farm — How Players Are Stacking an “Infinite” Resource

🚨 THIS MORTAL SHELL II FARM IS COMPLETELY ABSURD — INFINITE GRISHA REMNANTS?!

Grisha Remnants are supposed to be a rare, limited resource… yet players have discovered a hidden route that lets you kill the same Grisha, reload, and keep collecting Remnants over and over. And the more you stack, the stronger your Grisha summon becomes. 😳

But there’s a catch: you need the Slayer Seal, a hidden entrance, a specific reset method — and one tiny mistake can ruin the entire farm. Worse, this looks like unintended behavior that could disappear in the next patch…

🔥 Here’s the FASTEST Grisha Remnant farm currently working in Mortal Shell II — before it gets nerfed 👇

There are rare items in Mortal Shell II that players expect to collect only a handful of times during a normal playthrough.

Grisha Remnants are one of them.

The item is not merely another collectible. It can become the foundation of an entire summon-focused build, allowing the Harbinger to call a Grisha ally into combat and eventually scale that summon as more Remnants are collected. Current databases describe the Remnant as usable both actively and passively, with the passive version giving melee attacks a chance to trigger a Grisha summon automatically.

Normally, that makes every Remnant valuable.

But players have discovered something that changes the equation entirely.

A hidden dungeon contains a respawning Grisha that can drop another Remnant. By using the correct route and resetting the encounter through a Beacon, players can repeatedly return to the same enemy and continue farming.

And that is why this farm has become one of the most talked-about resource exploits in Mortal Shell II right now.

There is an even more extreme version involving a bell and spike pit near the Abandoned Outpost, where summoned Grishas can be made to fall to their deaths and generate additional Remnants. That method is even more obviously unintended — and current reports indicate it may already be under threat from upcoming balance changes.

For players who simply want the fastest reliable route, however, the hidden-dungeon method is the one to know.

Why Grisha Remnants Matter So Much

At first glance, farming another copy of an item might not sound particularly exciting.

The problem is that Grisha Remnant scales with collection.

Current game databases report that the item can be equipped as either an active or passive ability. As an active, it summons a Grisha to assist the player. As a passive, melee attacks have a chance to automatically trigger a Grisha summon.

More importantly, collecting additional copies improves the effect.

Current documentation reports that additional Remnants increase the player’s familiarity with the item, improving summon frequency and the summoned Grisha’s damage while also increasing the number of active summons available.

That creates a very unusual progression loop:

Find Remnant → summon Grisha → collect more Remnants → summon more often → make Grisha stronger → farm even more Remnants.

Normally, that progression is limited by the finite number of Grisha-related encounters in a playthrough.

The hidden farm breaks that limitation.

The Fast Farm Starts in Marrow Keep

The first requirement is the Slayer Seal.

The item can be obtained in Marrow Keep, and current guides repeatedly emphasize an extremely important warning:

Do NOT equip it.

You need to carry the Slayer Seal, but equipping it activates its associated easy-mode effect and permanently disables achievements and trophies on that save file.

So the rule is simple:

Pick it up.

Keep it in your inventory.

Do not put it into your equipment slot.

That distinction is easy to miss, particularly when the item looks like something the game expects you to use.

For this farm, it is effectively a key.

Nothing more.

Finding the Hidden Entrance

Once the Slayer Seal is in your inventory, return to the appropriate area beneath Marrow Keep.

The entrance is deliberately hidden.

Current walkthroughs describe breaking through an invisible wall inside the training-room area, revealing a hidden chamber containing a chained chalice.

This is the point where the route starts to feel less like conventional farming and more like one of those secrets players weren’t necessarily expected to discover immediately.

Break the hidden wall.

Enter the chamber.

Find the chained chalice.

Then use the required interaction to open the route.

From there, you can access the hidden dungeon referred to by current guides as Desolate Keep.

Enter Desolate Keep

The hidden dungeon is where the actual farm happens.

Once inside, the player needs to progress through the initial area and activate the appropriate mechanism to open the route toward the lower section.

Current walkthroughs describe using a switch/lever in the large room before crossing the ramp and dropping down toward the Grisha encounter.

This part of the route only needs to be learned once.

After that, the farming loop becomes much shorter.

And then you meet the important enemy.

The Respawning Grisha

At the lower section of Desolate Keep is the Grisha you are actually here to farm.

Kill it.

Collect the Grisha Remnant.

And now comes the trick.

The enemy is not permanently dead.

Current guides report that the Grisha can respawn after the player leaves the dungeon, rests at a Beacon and returns.

That transforms what should be a rare permanent pickup into a repeatable resource.

The basic loop becomes:

Enter Desolate Keep → kill Grisha → collect Remnant → leave → rest at Beacon → return → kill Grisha again.

And repeat.

The Reset Method Matters

This is where different versions of the farm become important.

The conventional method is straightforward:

The Beacon rest is the critical reset.

Current guides specifically warn that leaving and immediately returning without resting can result in the chamber remaining empty.

However, another current guide describes a faster variation that uses Exit to Main Menu after collecting the Remnant, then reloads the save and returns the player to the last Beacon without sacrificing the resources collected during the run.

That can remove a significant amount of travel time.

For players specifically looking for the fastest possible farm, that reset method is potentially the key difference.

Why You Shouldn’t Use Mother’s Breath

There is another way to leave the hidden dungeon:

Mother’s Breath.

But current farming guides warn that using it comes with a resource cost.

If the goal is to maximize Remnants per hour, sacrificing resources every run defeats much of the point.

The better approach is to use the normal exit or the menu-reset method, depending on which version of the route works on your current build.

That also means you don’t need to repeatedly fight your way through the dungeon from scratch.

How Many Remnants Should You Farm?

This is where things become subjective.

Current guides recommend getting roughly five to ten starter Remnants before moving on to the more aggressive exploit variant. The reason is that the passive summon chance scales with the number of Remnants already collected.

In other words, the farm becomes more efficient as your collection grows.

And that’s an important mechanic.

Suppose the passive summon initially has a low chance to trigger.

You don’t want to stand around swinging a weapon thousands of times hoping for the effect.

But after stacking more Remnants, the summon becomes significantly more frequent.

That creates a snowball effect:

More Remnants → more summons → stronger Grisha build.

One current guide even describes the theoretical endpoint as approaching a summon on virtually every swing once enough copies have been accumulated, although that should be treated as a scaling illustration rather than a normal intended progression target.

The Bell Pit Exploit Goes Even Further

If the Desolate Keep method isn’t broken enough for you, the community has found another route.

And this one is considerably stranger.

Near the Abandoned Outpost is a bell-and-spike-pit setup.

The player equips Grisha Remnant as a passive effect, stands at a very specific position beside the bell and repeatedly swings a fast weapon.

The passive effect can summon a Grisha.

If the summon appears above the spike pit, it falls and dies instantly.

And according to current reports, that death can produce another Grisha Remnant.

So the loop becomes:

Swing → Grisha spawns → Grisha falls → Grisha dies → Remnant drops → repeat.

No boss fight.

No dungeon run.

No conventional enemy farming.

Just repeatedly attacking near a bell while your summoned monster throws itself into a death pit.

It is difficult to imagine a clearer example of unintended game behavior.

Why the Bell Farm Is So Powerful

The biggest advantage is that once properly positioned, the player can remain almost completely stationary.

Current instructions recommend using a fast-swinging weapon to maximize the number of summon attempts.

The player should also favor the bell side of the location rather than the exposed rail.

Why?

Because the rail can cause summoned Grishas to appear across the gap — and potentially cause the player themselves to fall.

The intended setup is therefore extremely simple:

Stand safely beside the bell.

Swing continuously.

Let the pit kill the summoned Grishas.

Collect the Remnants.

The player doesn’t even need to personally kill the summoned Grisha.

The environment does it.

But There Is a Catch

There is a reason this method is being described as an exploit, rather than a farming route.

It is almost certainly not intended behavior.

Current reporting explicitly describes the bell-pit technique as unintended and warns that a balance update was rolling out around August 21 that could close the exploit.

That means players should not assume every video showing the trick will remain accurate.

Mortal Shell II is actively receiving balance changes.

A farming exploit can disappear overnight.

And because this particular method relies on a very specific interaction between:

passive Grisha summons,
environmental death,
Remnant drops,
and the bell-pit positioning,

it is exactly the kind of mechanic a developer can potentially fix without changing the broader Grisha system.

What If the Farm Doesn’t Work?

This is important because current sources are already showing differences between builds and platforms.

The Desolate Keep route is currently reported as working in the launch-era/Balance Patch 1 environment, while the Bell Pit exploit has more uncertainty because of the ongoing balance changes.

If you enter Desolate Keep and the Grisha doesn’t respawn:

Rest at a Beacon.

Don’t simply leave and immediately come back.

Current documentation specifically identifies the Beacon rest as the reset trigger.

If you’re using the menu-reset version, verify that the game has actually returned you to the Beacon state before entering again. Current video descriptions also caution that the method can vary by platform and game version.

And if the Bell Pit version no longer produces Remnants?

That may simply mean the exploit has been patched.

Don’t Forget the Legitimate Grisha Remnants

The farm is powerful precisely because normal Grisha Remnant acquisition is relatively limited.

Current databases identify several legitimate sources, including specific Grisha encounters and a potentially missable merchant copy.

One current guide specifically warns players to check the Grisha Hunter’s shop before progressing the relevant event because the merchant’s inventory can become unavailable afterward.

That means completionists should not automatically rush into the exploit.

You should first collect the Remnants available through normal progression.

Then use the farm if you want to push the summon system beyond its intended limits.

The Grisha Build Gets Increasingly Ridiculous

This is the real reason players care about the farm.

The Remnant isn’t just another resource that lets you buy something.

It directly feeds a combat mechanic.

As your collection grows, your Grisha summon becomes more useful.

That means an enormous Remnant stack can transform the player’s combat rhythm.

Instead of:

Attack → dodge → attack → dodge

you can eventually move toward:

Attack → summon → attack → summon → attack → summon.

The Grisha effectively becomes a second source of pressure.

And because the player isn’t manually controlling it, the summon can operate alongside the player’s normal weapon attacks.

Current community testing has therefore started treating high-Remnant builds almost like a separate archetype: the Grisha summoner.

Is This Actually Worth Doing?

For a first blind playthrough?

Probably not.

Farming dozens of Remnants can massively distort the game’s progression.

If you’re constantly surrounded by summoned Grishas, enemies may stop feeling threatening.

Bosses that were designed around learning attack patterns can become much easier when additional AI-controlled damage sources are constantly attacking them.

But for:

NG+ experimentation,
challenge builds,
testing summon scaling,
speed farming,
or simply seeing how ridiculous the mechanic can become,

it’s hard to ignore.

The current community is essentially asking a very simple question:

How far can Grisha Remnant scaling actually go?

And the answer may be much farther than the developers originally intended.

The Fastest Current Route, Simplified

If you want the short version, here’s the complete farm:

STEP 1

Go to Marrow Keep.

STEP 2

Pick up the Slayer Seal.

Do NOT equip it.

Equipping it disables achievements/trophies on the save.

STEP 3

Enter the training-room area.

STEP 4

Break through the hidden/invisible wall.

STEP 5

Find the chained chalice.

STEP 6

Use it to access Desolate Keep.

STEP 7

Activate the required switch/lever.

STEP 8

Reach the lower area.

STEP 9

Kill the respawning Grisha.

STEP 10

Collect the Grisha Remnant.

STEP 11

Exit.

STEP 12

Rest at a Beacon.

STEP 13

Return to Desolate Keep.

STEP 14

Kill the Grisha again.

STEP 15

Repeat until you’ve collected as many Remnants as you want.

Current reporting also documents a faster Exit to Main Menu → reload → return to last Beacon reset that can avoid losing resources or walking back through the dungeon.

The Bottom Line

Grisha Remnants are supposed to be rare.

That’s what makes this farm so ridiculous.

The normal game gives players a relatively small number of opportunities to collect them. But the hidden Desolate Keep route currently allows players to repeatedly kill a respawning Grisha, reset the encounter and collect another Remnant.

And then there’s the even crazier Abandoned Outpost Bell Pit exploit, where passive Grisha summons can be made to fall into a spike pit and potentially generate additional Remnants without conventional combat.

For anyone building around the Grisha summon, this is potentially enormous.

More Remnants mean more scaling.

More scaling means more summons.

And more summons mean a combat system that can start looking less like a Soulslike duel and more like you’re bringing an entire supernatural squad to every fight.

But don’t forget the biggest warning:

These are not guaranteed permanent mechanics.

The Bell Pit method is explicitly being reported as unintended, and current sources warn that balance changes may already be targeting it.

So if you’re determined to build the most ridiculous Grisha setup possible, the message from the community is pretty clear:

Farm it while it works.

Because once the patch arrives, that little spike pit might stop being the most profitable piece of real estate in Mortal Shell II.
