Mortal Shell II All 44 Bosses: Locations, Beacons, and Drops Checklist

Mortal Shell II does not hand you a boss log. There is no in-game counter, no map markers, and the open structure of Fainweald means you can miss an entire regional boss by walking past the wrong Beacon. This guide compiles every confirmed boss encounter, the nearest Beacon or dungeon entrance, and the guaranteed drop. Treat it as a completion checklist: work region by region, and do not assume clearing a zone’s main boss means the zone is done.

Why the Boss Count Reads Differently Across Sources

You will see three different numbers floating around: a “10 bosses in order” framing, partial lists of 13, and a full roster of 44. They are not contradictions. The ten-in-order figure refers to the story-critical gate guardians and the Unfound Path finale. The 44 figure counts every major and regional encounter, including dungeon bosses and world bosses that are easy to skip.

Source framing	What it counts	Confirmed by
~10 main bosses	Gate guardians + Unfound Path finale	captain-carry, gamespot
13+ (work in progress)	Early confirmed list	rockpapershotgun, sportskeeda
44 total	All major + regional + world bosses	grindnstrat

If your goal is the ending, chase the ten. If your goal is the platinum or the loot, use the full regional tables below. [Unverified] Some outlet lists place Hexapod in the Ruins of Mammon while others place it in Withered Shoals; treat its regional tag as provisional until patched.

Early Zones: Disciple’s Pass and Fainweald Boss Map

These are the first bosses you meet after the prologue. Disciple’s Pass is a gentle on-ramp; Fainweald is where the optional hunts that pay out Shells and levers begin.

Boss	Nearest Beacon / Entrance	Key Drops
Gloombound Ritualist	Past Village Outskirts Beacon, sunken tunnel	Gloom x360
Tainted Vestige	Near Disciple’s Grotto Beacon, left exit grove	Gloom x2,412; Burnt Effigy x1
Tar Golem	Down slope past Disciple’s Grotto Beacon	Vatra’s Seal
Great Arbiter of Flesh	Widow’s Overlook Beacon, by cemetery	Gloom x5,754; Glimpse x1; Arbiter’s Prize x1
Vrannic, the Grand Illusionist	Cleanse Mushroom Village Gate Beacon (Hall of Illusions)	Gloom x3,018; Volatile Fragment x1; Glimpse x1
Grisha	Flooded Village dungeon, deep arena	Gloom x2,331; Synaptic Vessel x1; Grisha Remnant x1
Vrago, Solikar Champion	Cleanse Nochtean Gate Beacon (Abandoned Shrine)	Glimpse x2; Voltaic Crown x1
Bloodcursed Lithopod	Gloomshade Grove, by the small lake (world boss)	Gloom x2,895; Citadel Gate Lever x1
The Warden	Center of Citadel of Penance	Gloom x6,542; Eredrim Shell
Rabid Grisha Pack	Bottom of Holding Cells dungeon	Grisha Remnant x1; Inflamed Clawstone x1; Gloom x1,132
Lucian, the Thirsting Knight	Cleanse Stonebled Gate Beacon (Hidden Keep)	Glimpse x1; Serpent Stone x1; Gloom x7,474
Pale Grisha	Grisha Hunting Grounds	Revered Gland x1; Grisha Remnant x1; Gloom x7,012

Two of these matter far beyond their loot. Lucian is mandatory: clearing Hidden Keep opens the Sanguine Caverns route. Vrago is mandatory: clearing the Abandoned Shrine opens Prisoners’ Domain. Bloodcursed Lithopod and The Warden are the difference between a locked Citadel and a fully open one.

Mammon, Glutted Mire, Sanguine Caverns, and Prisoners’ Domain

Ruins of Mammon is the densest boss region in the game and the spot where under-leveled players get flattened. Clear the lighter gates first.

Boss	Nearest Beacon / Entrance	Key Drops
Circle of the Grasping Root	Cleanse Seeping Mire Beacon (Rootwater Hollow)	Gloom x886; Coin x50
The Wandering Shepherd	Past bridge by Sunken Village Beacon	Gloom x6,462; Sheephead Totem x1
Tarblighted Stoner	Past Sanguine Caverns Beacon	Tarred Fragment x1; Gloom x6,935
Tishina’s Confessor	End of Slumwater Drain, Prisoners’ Domain	Confessor’s Keepsake x1; Gloom x5,664
Gloombound Legion	Cleanse Hangman’s Scaffold Beacon	Gloom x1,208
Vellen, High Lord of Mammon	Dungeon near High Lord’s Courtyard Beacon	Glimpse x1; Gloom x9,332
Twin Sesters	Cleanse Sester’s Gate Beacon	Gloom x2,197
Stray Sesters	Cleanse Sester’s Gate Beacon	Black Needle x1; Sester’s Crest x1; Gloom x6,890
Sester Secundus	Sester’s Censer Dungeon	Glimpse x1; Sester’s Censer x1; Gloom x5,443
Bor, the Deluded Monarch	Cleanse Abbey Entrance Beacon	Glimpse x1; Monarch’s Vestige x1; Gloom x9,241
Sariel, the Endless	Platform north of Chamber of Becoming (phase 2 inside)	Gloom x3,500; Glimpse x1; Clockwork Scythe x1; Sariel Shell
Gloombound Wraith	Cleanse Gate of Infinity Beacon	Glimpse x2; Curseblood Stone x1; Gloom x5,931
Starved Harridan	South of Castigator’s Keep Beacon	Voltaic Essence x1; Voltaic Amber x1; Gloom x15,165
Viletongue Batushka	Cleanse Castigator’s Keep Beacon	Glimpse x1; Sage’s Gate Lever x1; Viletongue Hedron x1
Subjugated Guardian	Sentry’s Grave Dungeon	Ballistazooka x1; Gloom x7,008
Infested Miner	Cleanse Gate of Mammon Beacon (teleports to Burrowkin Dwelling)	Wretchcaller’s Stone x1; Glimpse x1; Ventrium x1; Laterite x1; Dorsalite x1
Prophet of Profane Infinities	End of Obsidianite Mines, bottom of Deserted Slums	Obsidian Hammer x1; Paradoxical Scripture x1

Sariel and Viletongue Batushka are the standouts here. Sariel permanently unlocks the Sariel Shell plus the Clockwork Scythe. Batushka drops the Sage’s Gate Lever, a hard progression key.

Late Gates: Withered Shoals, Conquered Temple, Faded Citadel

These three gates sit after Mammon and before the Unfound Path. The Faded Citadel’s Isaac is the gate that finally hands you the Ova to open the endgame.

Boss	Nearest Beacon / Entrance	Key Drops
Strange Grisha	Withered Shoals	Grisha Remnant x1; Strange Remnant x1; Gloom x1,835
Hexapod	Ruins of Mammon / Withered Shoals [Unverified region]	Hexapod Core (Axatana ability Tarstone)
Urrig, the Executioner	Conquered Temple	Warden’s Stone x1; Gloom x6,115
Droeg the Conqueror	Conquered Temple, snowed dungeon	Conqueror’s Reward (Black Needle); Frostshard Stone beyond
Servants of the Scholar Prince	Cleanse Citadel Atrium Beacon	Gloom x1,579
Solnir, the Gloom Seeker	Cleanse Faded Citadel Gate Beacon	Glimpse x1; Solnir Shard x1; Gloom x13,885
Isaac, the Scholar Prince	Faded Citadel, final gate	Scholar’s Wormstone (Clockwork Scythe); Ova that open Unfound Path

Unfound Path Endgame: Tendril Guardians and Zmey

The Unfound Path opens only after you have collected enough Ova (reported as 168) at the Gloom Siphon in Marrow Keep. Three tendril guardians block the route to the center and can be fought in any order.

Boss	Nearest Beacon	Key Drops	Notes
Orrem, the Reclaimed	Bridge of Procession Beacon	Orrem’s Head (trade for 5,000 Coin); Gloom x64,442	Two phases, do not burn all flasks early
The Monolith	Obsidian Vault Beacon	Monolith Fragment (trade for 5,000 Coin)	Two phases, spinning beams at half health
Malborn Offspring	Faithful’s Shelter Beacon	Offspring Trophy x1; Gloom x63,333	Widely considered harder than the final boss
Zmey, the Unbidden	Past Hidden Nave Beacon (updraft)	None	Final boss; see dedicated guide

Missable Levers, Shells, and High-Gloom Payouts

A handful of drops are easy to miss and painful to redo. The Citadel Gate Lever (Bloodcursed Lithopod) and Sage’s Gate Lever (Viletongue Batushka) gate entire regions. Four Shells are boss drops: Eredrim (The Warden), Sariel (Sariel, the Endless), plus two more tied to optional fights. The biggest Gloom payouts are Malborn Offspring (63,333) and Orrem (64,442) — dump that into Harbinger levels and Tarstones before any repeat attempt.

Because Beacons are sparse and there is no fast travel between regions except through them, cleanse and rest at each one before a boss. Walking into an arena at half resources is how runs get wasted.
