Don’t Ruin Your Mortal Shell II Run: 7 Mistakes New Players Need to Avoid

Mortal Shell II has only been out for days, but players are already discovering that the game’s biggest threats are not always the bosses waiting at the end of a dungeon. Sometimes, the most damaging decisions are made much earlier — when a player spends a valuable resource, ignores a system, rushes into a fight or simply fails to understand how progression works.

That has made beginner advice particularly important in the game’s first week. Community discussions have quickly filled with warnings about wasted resources, lost Gloom, underdeveloped Shells, Tarstones and the temptation to rush through areas without fully understanding the game’s systems. One widely shared beginner thread on Reddit collected more than 190 upvotes shortly after launch and highlighted several of exactly these problems, including resource management, Tarstone progression and the cost of using Shell maps.

At the same time, Cold Symmetry has already changed some of the economy rules through its first balance patch. Shell map locations now use Gloom rather than Glimpses, previous Glimpse spending on those maps is being refunded, enemy Gold drops have been increased and weapon smelting at the Tarforge has become dramatically cheaper.

For new players, the lesson is simple: Mortal Shell II rewards experimentation, but it can punish uninformed experimentation.

Here are seven mistakes worth avoiding.

1. Spending Glimpses Without Understanding Their Value

Few issues generated more frustration during launch week than Glimpses.

Before the first balance patch, players could spend Glimpses to obtain information about Shell locations, and some players also used the resource on other progression options. Reddit discussions quickly warned newcomers that Glimpses were scarce and that spending them too casually could leave a player unable to develop the Shells they actually wanted. One highly upvoted discussion described the problem bluntly: players could either hoard Glimpses out of fear of making the wrong decision or spend them early and later regret spreading the resource too thin.

However, there is an important update here.

Cold Symmetry’s first balance patch changed Shell map locations so that they cost Gloom, while Glimpses previously spent on those maps are being refunded. The developers said the change was intended to prevent finding a preferred Shell from competing with the resources needed to bond with that Shell.

So the current advice is more nuanced than the launch-week advice.

Do not blindly spend rare resources simply because the game offers you an option to do so. But players following older guides should also make sure they are not treating the original Shell-map economy as if it still exists unchanged.

2. Treating Every Resource Like It Is Easily Replaceable

Mortal Shell II encourages exploration, but that does not mean every resource should be spent immediately.

Gloom, Gold and upgrade materials all have important roles in progression, while players can also become attached to a particular Shell or weapon and discover that moving resources around is more complicated than expected.

That tension was repeatedly mentioned by players during launch week. One Reddit player described losing thousands of Gloom while trying to push forward rather than banking the resource first. Another warned that switching Shells midway through progression could leave a player with an underdeveloped replacement.

This is particularly important for players coming from more forgiving action RPGs.

If you are close to a meaningful upgrade, continuing to explore while carrying a large amount of currency may not always be worth the risk. Sometimes the smarter move is to secure the resources you already have before taking another gamble.

That is not playing cautiously for its own sake.

It is understanding what the game is asking you to risk.

3. Ignoring Tarstones

Tarstones are easy to underestimate during the opening hours.

They can look like secondary customization items while a new player focuses on Shell abilities and weapon upgrades. But community experimentation has increasingly shown that Tarstones can substantially change how different builds function.

The beginner community has even developed the habit of equipping Tarstones early, including ones they do not immediately intend to use, because progressing their familiarity can generate resources for further upgrades.

That makes ignoring Tarstones one of the more expensive beginner mistakes.

The system is not simply about finding a Tarstone that looks powerful and equipping it forever. Players need to understand what their current weapon, Shell and combat approach are trying to accomplish.

The wider community is already experimenting heavily with combinations involving different weapons and Shells, with some players reporting that particular Tarstones can dramatically alter encounters.

The broader lesson is straightforward:

Don’t treat Tarstones as optional decoration.

They are part of the game’s buildcrafting system.

4. Upgrading Everything Instead of Committing to a Core Build

Another common trap is trying to make everything usable at once.

The game’s large selection of Shells, weapons and customization options naturally encourages experimentation. But early resources can make that experimentation expensive.

Players have already reported situations where they upgraded one Shell, switched to another and then found themselves significantly behind on progression.

That does not mean players should never experiment.

Quite the opposite.

It means experimentation should happen before committing large amounts of scarce upgrade resources.

Find a weapon whose moveset you actually enjoy. Find a Shell whose abilities complement your preferred style. Test them against ordinary enemies. Then start building around that combination.

The first week of community discussion suggests that players who attempt to level everything simultaneously can end up with several mediocre options rather than one properly developed setup.

5. Rushing Past the Game’s Combat Systems

Mortal Shell II removes the traditional stamina limitation, but that does not mean the game has become a button-mashing action game.

Steam’s official description emphasizes unrestricted combat while still placing heavy importance on tactics, Shell abilities, weapon upgrades and breaking enemy posture.

Community players are discovering the same thing from the opposite direction.

Some describe the early game as brutally punishing until they understand the combat systems. Others specifically recommend learning Harden and parry timing rather than attempting to overpower every enemy through raw aggression.

This is one of those cases where the game’s difficulty can initially feel higher than it actually is.

The player is not necessarily underpowered.

The player may simply be fighting the game incorrectly.

Learning enemy timing, understanding when to use defensive mechanics and recognizing opportunities to stagger or control enemies can make a bigger difference than simply chasing higher damage numbers.

6. Being Greedy With Gloom

This may be the most familiar Soulslike mistake on the list.

You have enough currency for an upgrade.

The checkpoint is close.

You think you can kill one more enemy.

Then another enemy appears.

Then another.

And suddenly the entire run is about recovering what you just lost.

Several launch-week Reddit discussions describe exactly this experience, including players losing thousands of Gloom while trying to push their luck.

Mortal Shell II makes this particularly relevant because its world and dungeon structure can create long stretches between safe opportunities.

The temptation is obvious: keep going because returning to safety feels inefficient.

But efficiency is meaningless if the next fight wipes out the currency you were trying to preserve.

Interestingly, Cold Symmetry’s first balance patch has reduced some of this economic pressure. Gold drops were increased significantly, with enemies in Mammon reportedly dropping twice as much Gold, while weapon smelting costs at the Tarforge were reduced by 75 percent.

That makes experimentation more affordable than it was at launch.

It does not, however, eliminate the value of knowing when to cash out.

7. Assuming Launch-Day Guides Are Still Completely Accurate

This may be the biggest meta-mistake of all.

Mortal Shell II launched on August 20, 2026, and received its first significant balance update almost immediately.

That means players searching YouTube, Reddit or TikTok for beginner advice can easily encounter information from different versions of the game.

A tip posted on launch day may have been completely accurate at the time but become outdated after a balance adjustment.

The clearest example is the Shell-map economy.

The initial player experience involved spending Glimpses to locate Shells. The first balance patch changed those map locations to Gloom and refunded previous Glimpse spending.

The same patch also changed Gold income, Tarforge costs, enemies, bosses, weapons and Tarstones. GamesRadar reported that the update included enemy health reductions, retimed attacks for some encounters and buffs to multiple weapons and Tarstones.

That means a guide’s upload date suddenly matters.

Before following a highly specific build or farming recommendation, players should check which version it was created for.

The Bigger Lesson for New Players

The fascinating part of Mortal Shell II‘s early community reaction is that players are not necessarily complaining about the game being too complicated.

They are discovering that the game often refuses to explain the consequences of a decision until after the decision has already been made.

That is why beginner communities have become so focused on resources, Tarstones, Shell progression, exploration and combat fundamentals. One popular Reddit guide even recommends marking completed dungeons on the map, equipping unused Tarstones to advance them and using the game’s auto-Gold pickup option.

At the same time, players should be careful about turning every community discovery into gospel.

Some of the game’s systems are still being discussed and tested. Players are debating the relative strength of different weapons, Tarstones and Shell combinations, while some claims about earlier beta values have already been disputed by other members of the community.

That makes the safest strategy surprisingly simple:

Experiment — but experiment intelligently.

Learn the combat systems before judging your build. Test weapons before pouring resources into them. Understand what a resource does before spending it. Keep an eye on your Gloom. Equip and experiment with Tarstones. And, most importantly, check whether the guide you are following was created before or after the latest patch.

Mortal Shell II is still in its opening weeks, and Cold Symmetry has already signaled that additional updates are planned, including further work involving Night Mode, Tarstones and other features.

For players just starting their first run, that means the current meta is anything but settled.

And perhaps that is the most important warning of all: don’t let an old guide ruin a new game.
