Part 18 of our Mortal Shell 2 walkthrough guides players through the western reaches of Mammon, focusing on the Deserted Slums region. This area serves as a gateway to the game's fourth legacy dungeon and contains several hidden secrets, including a new weapon, a unique NPC, and a hidden boss.
Entering the Deserted Slums
Begin by heading right from the Outskirts Of Mammon Beacon, past two Brigand camps and across a bridge. Descend either slope, dealing with Tarblighted Miners, and use the Bone Gate on the cliff edge to return to a previously explored section of Outskirts Of Mammon. Cross the subsequent bridges, eliminating any respawned Wretches and a Brigand Stoner. This path leads into the Deserted Slums.
Locating the Map and First Beacon
Upon entering the region, climb a wooden platform on the right to loot Common Moonshine. A Tarblighted Miner will drop down, so defeat it and proceed. As you enter a new area, a Headsman will descend. After defeating it and any approaching Miners, take the left path along a wooden walkway. Loot a Coin Pouch from a cart and continue, cutting through wooden pavises to find a Coin Of Mammon. Retrace your steps and take the parallel path, defeating a Stoner and Miner. Follow the alley between buildings and turn left, ascending a curved pathway. Kill a Subjugated Sentry and a Headsman. Turn left from the Headsman's position to find a Brigand and a Ventrium. Backtrack and take the first right to find Ruk's statue. Defeat the Tarred Corpses that spawn and loot the statue to obtain the Map Of Mammon [4]. Adjacent to the statue, activate the Lonesome Spire Beacon. Rest here before returning the way you came.
Reaching the Deserted Slums Beacon
Descend the slope, defeating the Sentry again. Take the first left at the bottom and defeat a Tarblighted Miner in a ruined hut. Exit the hut to the right, defeating enemies, then re-enter and take the direct exit, defeating another Stoner. Continue around the corner, defeat another Miner, and loot a Laterite and Common Moonshine from a wood cart and nearby. Return to the hut's entrance and turn left, breaking down wooden walls to progress. In the swampy pond area at the bottom, clear out all Miners. Near the pond's center, activate the Deserted Slums Beacon and rest.
The Obsidianite Mines
From the Deserted Slums Beacon, enter the dungeon entrance directly opposite. In the Obsidianite Mines, defeat the Miner at the elevator's base and avoid the collapsing floor to reach a Ventrium. Fall to the room below, defeat three Miners, and loot another Ventrium. Continue, defeating two Lithopods. In the next room, ascend a slope to kill a Batushka. Carefully drop down to lower platforms, defeating a Batushka on each. Drop to the floor below to loot three Bone Statues for Dorsalite. Use the air current to return and enter the boss room to face the Prophet Of Profane Infinities. This boss is a buffed Faceless Cleric; timed parries against its slow hammer attacks are effective. Upon defeat, you will receive the Obsidian Hammer weapon and a Paradoxical Scripture. Exit the dungeon via the glowing orb.
The Collapsed Mine
Use the elevator next to the Deserted Slums Beacon, riding it to the top. Defeat Miners and a Headsman, then loot a Ventrium from a cart. Take the left route from the elevator, cross a bridge, and defeat enemies before entering the Collapsed Mine dungeon. Defeat the Miner at the elevator's bottom. Destroy pavises to progress, defeating three more Miners and finding a Ventrium. Opposite, a chest contains the Shattering Stone Tarstone. At the room's far end, a narrow passage leads to an air current. Ride it up, defeating Netopyrs. Carefully drop to a halfway ledge to loot Laterite, then return to the top. This path leads back to the dungeon's entrance.
Navigating the Coffin Village
Beyond the Collapsed Mine dungeon entrance, use an air current, cross a bridge, and defeat enemies to return to the swamp area. Enter the hut opposite the bridge and exit to the left. Head to the wooden platform overlooking the swamp and pull a lever to activate an elevator, returning you to the swamp. Cross to the left side of the opposite elevator, find a doorway guarded by Brigands, and defeat them. Loot a Weltcap, then follow a path upwards, where you will be ambushed by a Ravenous Flesh. Dodge its initial attack and use repeated light attacks to stunlock and defeat it. You will then enter the Coffin Village. Loot a Coin Pouch and Laterite in an alleyway. In the village proper, head right past a noticeboard, sidling around the church to find a Synaptic Vessel among gravestones. Loot two Coin Pouch items near the noticeboard. Take the right path beyond the noticeboard, defeating more Ravenous Fleshes, and exit the village through a doorway guarded by a Tarblighted Miner.
Activating the Gate Of Mammon Beacon
Ignore the Bone Gate on your right. Defeat the Miners ahead and turn right for a Coin Pouch. Activate the Gate Of Mammon Beacon in front of you. This Beacon is crucial for accessing Mammon's first legacy dungeon, but it does not need cleansing yet. Rest here, then turn around and head back through the doorway.
Reaching the Abandoned Outpost
Take the left path back toward the well. Turn left and ascend steps to a walkway, finding a Coin Pouch. Return to the well and turn right. Ignore the elevator and proceed straight, taking the final left. Defeat Fleshes and a Miner, then turn right. Follow the path to the end, defeat a Miner, and use a Bone Gate to reach a higher ledge. Loot Dorsalite, then return across the gap. Head back into the village and take the first right, returning to the village center. Use the Bone Gate by the broken bridge to cross to the north. Defeat a Subjugated Sentry and find an Egon's Stone and Gloom on a slab. Follow the path to the right of the Bone Gate, then go up the stairs. A sign indicates a Nighttime-only secret. Ascend the stairs to find a sitting spot, a note on Mammon history, a Sheep, and Dorsalite. Defeat the Sheep for a Sheephead Totem. Backtrack down the stairs and continue up the slope, looting a Coin Pouch. Activate the Abandoned Outpost Beacon ahead.
Cleansing the Big Ol' Hole
Rest at the Abandoned Outpost Beacon and select "Cleanse Beacon." Open the chest for a large Coin amount, then descend the elevator into the Big Ol' Hole. Defeat the Armed Knave guarding the hole, destroy crates to reveal a new pathway, and collect Laterite from a Bone Statue. Continue, defeating another Knave. At the bottom, defeat two ice-element Skulks and loot another Laterite from a Bone Statue. Press the stone button on the wall and return to the top. A gate will have lifted; head through it, open a chest for the Accursed Stone, and cleanse the corruption for an Ovum and Glimpse.
Visiting the Collector at Night
To access the Collector's shop, return to Marrow Keep via the Abandoned Outpost Beacon and ascend the tower to speak with Thestus. Switch the world to Nighttime. Optionally, speak with Thestus as Eredrim for unique dialogue and a Glimpse. Fast travel back to the Abandoned Outpost Beacon, head up the stairs where the Sheep was found, and interact with the Collector. His shop offers various Tarstones, Glimpse, Thoracium, and a Blackmarrow Key. It is advisable to acquire the Blackmarrow Key if possible.
Clearing Bellkeeper's Corner
Head up the slope to the right of the Beacon, looting a Weltcap. Continue around the corner, defeating a Brigand Stoner. At the subsequent Bone Gate, turn around and ascend a stone walkway. Use your Sidearm to shoot the bell above, creating a bridge across a gap. Descend through the fog into the Bellkeeper's Corner dungeon. Defeat two Brigands and a Crossbowman. Shoot a bell to create another bridge, cross it, defeat a Stoner, and loot a Bone Statue for Laterite. Shoot another bell to create a bridge to a chest containing the Spite Stone Tarstone. Return the way you came.
Reaching the High Lord's Terrace Beacon
Head back down the stone slope and use the Bone Gate. Ascend the slope and proceed with caution, as a Knight Of Mammon is present and catapults fire from across the way. Defeat the Knight Of Mammon and two Foul Knights. Continue along the path, defeating another Foul Knight, until you reach a sitting spot on the cliff edge, next to a Beacon. Turn around to find a walkway overlooking the previous slope. Traverse this walkway to find two Mycellian Skulks guarding a Bone Statue; defeat them and loot the statue for Laterite. Return and activate the High Lord's Terrace Beacon.
This walkthrough concludes the exploration of the Deserted Slums. The next guide will cover the subsequent section of Mammon, starting from the High Lord's Terrace.
