Overview
Mortal Shell 2 ships with a full roster of boss fights spread across its compact open world, and the way guides count them varies. The most commonly cited framing is 10 major bosses — six that guard the Corrupted Gates on the critical path plus the endgame Unfound Path fights — with a larger rotating cast of minor and optional encounters on top. A dedicated checklist site (RPS) keeps a work-in-progress list that already passes 20 named encounters, and counts above that include dozens of small optional fights. None of these counts contradicts the others — they just use different definitions. This page uses the 10 major + minor framing, with the full confirmed roster listed below.
One caution: several low-quality sources circulating before launch invented boss names that appear nowhere else. Only encounters confirmed by multiple independent English guides are listed here.
Boss List

| 2 | Tar Golem | Disciple's Grotto | Minor |
| 3 | Tainted Vestige | Disciple's Grotto | Minor |
| 4 | Lucian, the Thirsting Knight | Hidden Keep | Minor |
| 5 | Great Arbiter of Flesh | Widow's Overlook | Minor |
| 6 | Magdalena, the Lady of the Woods | Mushroom Village Gate (Corrupted Gate) | Major |
| 7 | The Lost Child | Sanguine Caverns (Corrupted Gate) | Major |
| 8 | The Nameless Captive | Prisoners' Domain (Corrupted Gate) | Major |
| 9 | Droeg the Conqueror | Conquered Temple (Corrupted Gate) | Major |
| 10 | Hexapod | Withered Shoals (Corrupted Gate) | Major |
| 11 | Sir Isaac the Scholar-Prince | Faded Citadel (Corrupted Gate) | Major |
| 12 | Orrem (Discarded Golem → Reclaimed) | Unfound Path: Bridge of Procession | Major |
| 13 | The Monolith | Unfound Path: Obsidian Vault | Major |
| 14 | Malborn Offspring | Unfound Path: Faithful's Shelter | Major |
| 15 | Zmey the Unbidden | End of the Unfound Path | Final boss |
Because the ten major names are consistent across every reliable guide, those are the encounters this hub is built around. Additional minor bosses appear across guides (Vrannic the Grand Illusionist, Vrago the Solikar Champion, the Wandering Shepherd, Broodshell Swarm, Bloodcursed Lithopod, Rabid Grisha Pack, Gloombound Legion, Tishina's Confessor, Circle of the Grasping Root, Vellen High Lord of Mammon and more) — the roster keeps growing as completionist coverage lands, which is why some counts drift upward.
Major Bosses
The ten major bosses all sit at the end of a Corrupted Gate dungeon or in the endgame Unfound Path. There are six Corrupted Gate dungeons — Mushroom Village Gate, Sanguine Caverns (Stonebled Gate), Nochtean Gate and three in Mammon (Gate of Mammon, Conquered Temple, Withered Shoals) plus Faded Citadel — each ending in a major boss. Defeating one of these bosses spawns a Beacon holding 26x Ova, which you need to progress.
After the six gates, the endgame Unfound Path contains the remaining fights: Orrem, a two-phase battle at the Bridge of Procession that transforms from the Discarded Golem into Orrem the Reclaimed; The Monolith in the Obsidian Vault; Malborn Offspring at Faithful's Shelter; and finally Zmey the Unbidden, the final boss. Three of the Unfound Path bosses guard tendrils you must clear before the final encounter appears.
For several boss fights you can spend 1x Glimpse to permanently summon a Shell warrior as a spectral ally — a worthwhile investment for the hardest encounters such as Malborn Offspring.
How to Read This Guide
This guide uses the 10 major + minor framing because it is the most consistently cross-verified: GameSpot's ten-major-boss list and GameTrek's navigation list match almost exactly, and the same names appear in the dedicated location checklists. The Day One patch reworked Zmey the Unbidden and The Monolith with higher damage, and raised damage on Hexapod, Orrem, Malborn Offspring and Droeg the Conqueror. It also gave Sir Isaac more health and better stance-break resistance while trimming The Lost Child's health — re-check the patch-notes page if a strategy here feels different from the live build.
Each dedicated boss page covers full attack patterns and phase breakdowns: the final boss Zmey the Unbidden, the hardest fight in the game Malborn Offspring, and the late-game wall The Monolith.
