Mortal Shell 2 Unfound Path Walkthrough
Quick answer: Bring 168 Ova to the Gloom Siphon in Marrow Keep, open Unfound Path, and kill the three tendril guardians: Orrem, Monolith, and Malborn Offspring. Cleanse Hidden Nave for the Endless Core before Zmey. Beating Zmey does not end the run — Send Ova does.

Three branches
| Branch | Boss | Note |
|---|---|---|
| Bridge of Procession | Orrem | Two-phase Tar Golem rematch. Save flasks. |
| Obsidian Vault | Monolith | HP sponge and spinning beams. No listed summon. Patch 1 nerfed it. |
| Faithful's Shelter | Malborn Offspring | Often harder than Zmey. Lightning phase two. |
Hidden Nave before Zmey
- After the tendrils fall, cleanse Hidden Nave in the middle of the zone.
- GameSpot's Endless Core route: second bonfire, return for a spawned torch, push through fog, follow the slope, open the chest.
- Install Endless Core at the Tarforge to remove the weapon level cap.
- Unequip Grisha Remnant before the Zmey updraft.
Do not Send Ova from the Gloom Siphon until cleanup is done. Zmey is not the lock.
