Futilium is one of those materials in Mortal Shell 2 that can leave you wondering whether you have found something important or simply another resource to stockpile. Unlike more straightforward smithing materials, the game gives you very little context when you first pick it up. Futilium is among the game’s upgrade materials, but its item description is deliberately cryptic: “The pursuit of purpose ends with life.”
The important part is that Futilium appears to be exceptionally limited. There is a known Futilium location in Fallgrim, making it considerably rarer than materials such as Ventrium, Laterite, Dorsalite, or Ossinite.

How to find Futilium in Mortal Shell 2
The currently confirmed Futilium pickup is located inside The Hidden Nave, a late-game beacon dungeon associated with The Unfound Path. This area is reached close to the end of Mortal Shell 2, so you should not expect to find Futilium during your early exploration of Fainweald or Mammon.
The Hidden Nave is particularly easy to get turned around in because of its dense fog. The dungeon contains a torch mechanic that you need to understand before you can properly navigate through the area. The same dungeon also contains the Endless Core, an important late-game item that removes the normal +16 weapon and sidearm upgrade ceiling when installed at the Tarforge.
How to reach the Futilium pickup
- Enter The Hidden Nave.
- Reach the second campfire.
- Return to the first campfire and collect the torch.
- Carry the torch through the fog.
- Follow the path to the flooded chamber.
- Look for the glowing pile of bones.
- Interact with the bones to collect Futilium.
What is Futilium used for?
This is where Futilium differs from most of Mortal Shell 2’s clearly explained materials. Its confirmed practical use has not been clearly documented in the current post-launch sources.
The item is categorized as an upgrade material on current interactive maps, and the dedicated database lists it as an uncommon pickup. However, the current item database does not provide a specific crafting recipe, Tarforge upgrade, weapon level requirement, or NPC exchange for Futilium.
That distinction matters because several other materials have much clearer functions. For example, Ossinite is explicitly consumed by the Tarforge for weapon improvements, while the Endless Core is specifically installed to remove the weapon and sidearm level cap.
| Material | Current documented role |
|---|---|
| Ventrium | Weapon upgrade material |
| Laterite | Weapon upgrade material |
| Dorsalite | Higher-tier weapon upgrade material |
| Ossinite | Tarforge weapon improvement |
| Futilium | Upgrade-material classification; specific use currently unclear |
| Endless Core | Removes the +16 upgrade ceiling |
Because of this, do not assume Futilium is useless simply because no current menu lets you spend it. Its placement as a rare pickup and its classification among upgrade materials suggest that it has a purpose, but the currently available documentation does not establish exactly what that purpose is.
How Futilium relates to late-game upgrades
Futilium is particularly interesting because its only currently mapped pickup is associated with The Hidden Nave, which is itself an endgame location containing the Endless Core. That means you encounter the material at roughly the same point where Mortal Shell 2 begins opening its highest-tier upgrade systems.
Once you obtain the Endless Core, you can return to the Tarforge and install it manually. This raises the upgrade ceiling beyond +16, with later weapon levels requiring progressively rarer smithing materials. Current documentation identifies Theoracium and Ossinite among the higher-tier materials used after the cap is removed.
Futilium, however, should not currently be substituted for those materials. There is no reliable current evidence that Futilium is required for the standard +16-and-beyond weapon upgrade path.
Should you keep Futilium?
Yes. Given its rarity and the fact that current maps identify only one pickup, the safest approach is to keep every Futilium you find.
There is little reason to treat it as a normal consumable or ordinary sellable loot. Its description provides no indication that it should be consumed, and the available item database does not currently document a trade value or ordinary merchant function.
If a future update, quest, crafting system, or newly documented interaction reveals its purpose, having the material already stored will save you from having to revisit a difficult late-game dungeon.
| Reward | Amount | Location |
|---|---|---|
| Futilium | 1 documented pickup | The Hidden Nave |
| Endless Core | 1 | The Hidden Nave |
| Glimpse | Multiple possible pickups | The Hidden Nave |
| Lore/engravings | Several | The Hidden Nave |
The Futilium pickup is therefore best treated as a rare collectible material rather than a directly usable upgrade item for now. The Hidden Nave itself is still worth completing because the dungeon contains the Endless Core, which has a clearly established function and allows weapons and sidearms to progress beyond their previous +16 ceiling.
