Mortal Shell 2 Upgrade Materials: What to Save and Where to Spend
A spend-first guide for deciding which materials improve the next route and which should stay in storage.
Save rare materials until you know the next bottleneck. Spend on the weapon, Shell, or system that removes the problem blocking your route.
5 sources · reference table included · No exact costs are invented when evidence is missing.- A target upgrade

The useful details at a glance
Use these rows before opening a long route. Status tells you what is confirmed and what still needs a retail check.
Do this in order
Three short actions to turn this page into a usable run. This page stays text-first because no exact visual was verified.
Write the bottleneck
Is the problem survival, reach, posture, or route access? The answer decides which material deserves the next spend.
Farm only after the use is known
A source route without a destination creates wasted runs. Link every material to a weapon, Shell, Tarstone, or boss plan.
Keep a buffer for the next gate
Do not empty the inventory on a theoretical upgrade. Keep enough for repairs or the next verified checkpoint.
Separate costs from advice
Show exact material and cost only after a retail check. Planning advice can tell you what to reserve, but it must not look like a verified number.
Upgrade the bottleneck
Choose the spend that removes a route bottleneck: surviving a boss, reaching an area, or maintaining the weapon you actually use.
Link every material to its use
Connect each material to the weapon, Shell, Tarstone, or system that consumes it. A farming route needs a destination.
Tarforge checklist: unlock the station before farming
The five-part activation route is the practical backbone: Muradean Actuator first, then the Obsidian Lathe, Etching Needles, Foundry Stone, and the late Endless Core. The first four are handed to Franz in Marrow Keep; the Endless Core is installed through the Tarforge menu according to launch coverage.
Once the station is active, the page should tell you what the next spend consumes. A weapon material without a weapon, sidearm, or Tarstone destination is not a farming plan—it is an inventory number with no decision attached.
Smelting is a reset tool, not a free reroll. Confirm the current refund and Gloom cost before using it, and keep a reserve for repairs or the next gate.
Spend-before-farm checklist
A farming route needs a destination and a reserve.
| Check | Do this |
|---|---|
| Bottleneck | Name the route, boss, survival, or access problem. |
| Consumer | Link the material to a weapon, Shell, Seal, or Tarstone. |
| Source | Record the route and current evidence state. |
| Spend | Upgrade the item you will actually use today. |
| Reserve | Keep a buffer for the next confirmed gate. |
