Mortal Shell 2 Quests Guide: All Main & Side Quests

Updated Sep 1, 2026 锝?Full walkthroughs, rewards & the missable secret ending
馃幆 TL;DR: Mortal Shell 2's quests are short and forgiving 鈥?there's no brutal sequence-locking like other Soulslikes. Do the Grisha Pup quest early (best value), don't miss the Baghead secret ending on Desolate Peak, and exhaust every dialogue option: almost every questline needs you to rest at a Beacon to progress.

1. The Main Quest 鈥?quickly

There's no quest log; the main path is simply: follow the Harbinger's goal of cleansing the realm for the goddess UnderMether. You recover Ova (eggs), cleanse six Corrupted Gates, and defeat the 10 story bosses, ending with Zmey, the Unbidden. The real turning point is the point of no return below.

鈿狅笍 The point of no return 鈥?"Send Ova": After you beat the final boss, the Gloom Siphon in Marrow Keep offers a "Send Ova" prompt. Selecting it plays the ending and starts New Game Plus. It can't be triggered accidentally 鈥?you first need 168 Ovum (the six Corrupted Gates give the bulk of it). Finish everything you want before choosing it.

3. The Golden Rule of Questing

馃棧锔?Rest to progress: Almost every quest in Mortal Shell 2 progresses only after you rest at a Beacon to reset the world. Talk to an NPC, rest, come back, repeat. Exhaust every dialogue option each visit 鈥?and re-check hub NPCs after every major boss.
