Mortal Shell 2 is generous about this by the standards of the genre — almost nothing in it closes behind you, and the things that do are countable on one hand. This page is that hand, sorted by consequence: just 1 that no later run gives back, and then the rest, which are worth knowing about and not worth panicking over.
How much of this actually matters?
Less than the word suggests. The great majority of this game's 53 trophies unlock along the route or wait patiently in a set you can finish whenever you like, and a second playthrough restores nearly everything a first one skipped. The pages this one links to place those on the route rather than repeating them here.
What is left is a short list, and the nastiest thing on it is in the prologue — before the game has explained what a trophy list is, let alone shown you one. If you read nothing else here, read the first section.
Every section below names the records it is about, and those records are ours: a trophy's condition is quoted from our trophy catalog rather than paraphrased, and an item's location comes off the item's own page. Where the community record is thin or split, the wording says so.
Gone for good1
Lose it and no later run gives it back. These are the only ones worth planning around.
The prologue boss, and the one trophy the game can take off you
Gone for good Route stop 1: Forlorn Village.
The Tar Golem cannot be beaten in the sense of surviving it — the fight ends in a cutscene whichever way it goes. But the trophy for taking it to its minimum health is real, and it is reported to close permanently the moment the fight ends the other way: being severed from Harros advances the story, and no later playthrough is said to reopen it.
That makes this the single most consequential five minutes in the game for a completionist, and it happens before the game has explained what a trophy list even is. If you are going for everything, treat the prologue as a boss rush rather than as a tutorial.
The reported escape hatch is inelegant and effective: if the fight is going badly, throw yourself off the edge of the arena before you are severed. Dying to the fall is said to put you back just outside the door with the fight unresolved, which the cutscene would not have done.
Bronze — No, You Still Can't Win
Take the Tar Golem to his Minimum Health Trophy page
Missed now, available again next time. Annoying rather than fatal.
The trophy that asks you to stand in the attack everybody says to run from
Lost this run Route stop 11: Prisoner's Domain.
Our trophy record spells the condition out: Perfect Guard every one of the Nameless Captive's headspins, with the Untarnished Seal specifically. That is a named Seal and a named move, and the move is the one both wikis tell you to put as much distance between yourself and as possible.
So this is a trophy you have to go against the advice to earn, and it wants a clean run of them rather than one. Carry Guard rather than Parry or Harden into the fight — the condition names the Seal, and swapping later is a second attempt rather than a correction.
Unlike the prologue trophy, this one is not reported as closing behind you. The Captive is still there in a later run.
Bronze — Peter's Perfect Parry

Our catalog carries the trophy, the fruit, the mask it turns into and the item the whole thing runs on, and it never says out loud that they are one chain. They are. The Mether's Flesh comes out of a cavern branching off the Sanguine Caverns, and what it is for is not what its own description suggests.
That description is the trap. The record states plainly that the Flesh can be traded for a hundred Coin, and a hundred Coin is nothing — so a tidy inventory sells it without a thought and closes the chain in the same click. Keep it.
What is reported to happen next is that offering it to a large fish in water east of the Outskirts of Nochte beacon moves you somewhere else entirely, and the fruit is there. Our records say the fruit improves life and that equipping it in the passive slot is what turns it into a mask, which is two rewards for one errand.
Baghead holds court on Desolate Peak with a seated congregation and invites you to join it. Our trophy list carries the reward for this one and its condition is a joke about having mastered nothing, which is the clearest hint the game gives about what he wants.
The bottle is the test. Our own item record places a Special Moonshine on a crate by the dungeon entrance across from him, which is exactly the sort of detail that reads as an obvious offering. Every account we have found says the same thing: bring him that, or bring him anything, and he turns it down.
So what there is to protect is the state you arrive in rather than anything in your bag: take him nothing you picked up on his account, and do not treat one refusal as the end of the conversation. Where the questline goes after that is spoiler material, and this wiki keeps that behind a notice rather than in a list somebody opened to find out what they could lose.
Bronze — Bag Holder
You’ve mastered nothing and this is your reward. Pretty pointless, eh? Trophy page
The trophy that asks you to do something to somebody
Lost this run
Our trophy list holds one whose condition is causing Egon to pass away, and Egon is a person standing in a tower in Castigator's Keep who is not otherwise in your way.
Trophies of this shape are the reason to read a trophy list before the run rather than after it: an NPC who is gone is gone, and nothing in the game marks the ones whose deaths are recorded. It is filed here rather than under a walkthrough because the decision belongs to you and the consequence does not reverse inside a playthrough.
Not destroyed — simply somewhere else, or waiting on a step you have not taken.
The requests with no quest log behind them
Moves on without you Route stop 15: Outskirts of Mammon.
Mortal Shell 2 has no quest journal, which means every errand somebody asks you for exists only in the conversation you had and in whatever you wrote down. Several of them pay materials you would otherwise be buying, and one of them turns a drunk in a tavern into a Shell.
None of these is reported as timed. What they are is easy to forget, which produces the same outcome by a slower route — you reach the endgame holding a Weltcap you meant to give to somebody and a key you bought for a cage you never went back to.
The practical answer is to treat Marrow Keep as the checklist. If somebody in it wants something, that want is the only record of itself.
The trophies listed here name a whole set rather than one thing, and none of them is missable in the strict sense — every piece is still where it was. What makes them behave like missables is that finishing one at the end of a run means retracing a map you have already cleared.
The map fragments are the worst of them, because two of the ones you most want are not sold: they sit on monuments out in the world, which is a fair joke on anybody who wanted the map before the exploring. Pick up as you pass and none of these becomes a chore.
2, and they are different in kind from everything above. A missable is a thing you failed to pick up; a point of no return is the world changing shape around what you have left.
When the hub itself changes
Late game. This one is about a change to the hub in the last stretch of the story. Nothing below names a fight, but it does say that something happens.
Clearing the gates is what moves the story on, and at some point on that road Marrow Keep stops being the safe room it has been all game. The change is permanent, it opens ground that was not there before, and nothing warns you it is about to happen.
The two accounts we read do not agree on how many gates it takes — one says four, the other six. Our own beacon catalog settles the ceiling if not the trigger: there are six gates in the game and no more, so anybody quoting four is describing a change that happens before the last of them. Either way the advice is the same. Finish what you have left in the world before you open a gate you have not opened before.
The one door that only opens forwards
Starting a second run is the other point of no return, and it is the cleaner one, because at least it announces itself. What it costs is the state of the world you leave: cleansed beacons, opened chests, cleared dungeons and the errands you were partway through all reset.
There is reported to be no way back to the run you left. Anything you were saving to do later is now something you will do again from the beginning.
What to do about all of this
Three habits cover the whole page. Do the prologue boss properly rather than treating it as a cutscene. Read an item's record before you sell it, because one thing on this list is lost by tidying an inventory rather than by missing a door, and its record prices it at a hundred Coin as though that were all it was for. And finish what you are holding before you open a gate you have not opened before — our beacon catalog holds six of them, and the accounts disagree about which one changes the hub.
The rest is what a second run is for — and the argument for running one is on that page rather than this one, because “you can get it next time” is only reassuring if you know what next time keeps.
Written from our own catalog and from what the community has documented, checked against both of the major Mortal Shell 2 wikis. Where those two disagree, this page says so rather than picking one quietly.
