Mortal Shell 2: How to Cleanse the Gate of Mammon Beacon

The Gate of Mammon sits on the western side of the Ruins of Mammon in Mortal Shell 2, and cleansing its beacon is what opens the Corrupted Gate leading to the Withered Shoals. The beacon itself hides a short mini dungeon through the Burrowkin Dwelling, capped by the Infested Miner boss. Clear it and you walk away with the Wretchcaller’s Stone plus a batch of Ova for campaign progression.

Quick answer: Revitalize the Gate of Mammon beacon, choose Cleanse Beacon to enter the portal, ride the lift down into the Burrowkin Dwelling, pick up the Central Shaft Lever in the lower caves, defeat the Infested Miner to earn the Wretchcaller’s Stone, then collect the Ova to finish. The beacon reads BEACON CLEANSED once it is done.

How to reach the Gate of Mammon beacon

The Gate of Mammon is the easiest of the three Mammon Corrupted Gates to reach, since you can get there without crossing the Road of Absolution south of the Outskirts of Mammon beacon. If you have not tagged it yet, work your way to the western part of the region.

From the High Lord’s Courtyard beacon, take the southern exit and ride the elevator downward. This drops you toward the lower western reaches of Mammon.

Use the jump gate to land close to the Lonesome Spire. The Gate of Mammon beacon is right here, and it doubles as a good rest point before you climb the spire.

If you are coming from the Abandoned Outpost or the catapult area instead, follow the roads and bridges west of the Outskirts of Mammon beacon. You will pass a map fragment and reach a Bone Gate that carries you to the area with the Gate of Mammon.

Note: Mammon enemies hit harder than anything in Fainweald. If the Halberd Knights and mining foes on the way in are overwhelming you, spend more time leveling in Fainweald before returning.

Entering the portal and descending into the Burrowkin Dwelling

Interacting with the beacon opens its menu, which includes Cleanse Beacon, Level Up, Change Shell and Equipment, and Rest at Beacon. Selecting Cleanse Beacon pulls you into the corruption zone where the mini dungeon begins.

Walk through the white chamber and destroy the altar in front of you. This clears the way to the lift that takes you underground.

Ride the elevator down into the cavern and start following the lit path. You will fight hollow miners in the dark tunnels as you descend.

You will come to a gated lift mechanism showing the prompt The lever is missing. You cannot use it yet, so keep descending through the ramps and ledges to reach the lower cave levels.

Working through the caves to the Central Shaft Lever

Enter the wooden buildings of the Burrowkin Dwelling and clear the hostile miners inside. Break the white resin pillars as you go. There is a focus restore point in this wooden structure, so top off before pushing deeper.

Drop into the lower cavern and take on the large quadrupedal beasts waiting there. Defeating this group lets you pick up the Central Shaft Lever, the key item that powers the locked lift you passed earlier.

Use the spirit updraft (wind current) to fly up to the upper level of the dwelling. Along the cavern corridor above, clear the armored knight and the remaining miners.

If a fiery blockage is in your way, shoot the explosive barrel next to it with your crossbow to clear the path. Follow the tunnel toward the large cavern chamber ahead.

Infested Miner boss fight and the Wretchcaller’s Stone

Entering the large cavern chamber triggers the fight against the Infested Miner. The boss is backed by crab minions, so managing the smaller enemies is part of the challenge. Deal with the crabs when they crowd you, then punish the Infested Miner in the openings.

Defeating the Infested Miner rewards the Wretchcaller’s Stone, a Tarstone you can equip later. With the boss down, the corruption in the chamber can be cleansed.

Claim the Ova and confirm the beacon is cleansed

Interact with the glowing Ova at the end of the arena. The prompt NEW OVA FOUND appears, followed by Collect Ova and return to Beacon? Choose YES.

You are returned to the beacon, which now reads BEACON CLEANSED. That confirmation is how you know the run is complete. Beacons tied to major bosses hold the most Ova, so this is a meaningful boost toward the 168 Ova the campaign needs.

Head back into the beacon’s lift and follow the route down to the previously locked gate. Insert the Central Shaft Lever into its slot to open the gate and operate the lift, which restores the shortcut through the area.

With the beacon cleansed, the Gate of Mammon grants access to the Corrupted Gate: Withered Shoals, letting you push on with the western Mammon route whenever you are ready.
