You are required to Commune with Chaos behind the fake wall inside the Marrow Keep to teleport down into Desolate Keep in Mortal Shell 2. The reason you might be scratching your head is that nothing happens when you interact with the prompt, or it ends in failure. This guide explains what Commune with Chaos is and what you need to do with the chained chalice to unlock the dungeon.
What Does Commune with Chaos Mean?
Selecting “Commune with Chaos” activates a teleport ritual that sends you into the Desolate Keep, a hidden subterranean dungeon. The only good reason you’ll want to clear this dungeon is to retrieve a Blackmarrow Key from the chest. Blackmarrow Keys are spent in the launchpad elevator room at Marrow Keep to open locked relic chests. Every chest rewards an alternate Shade (skin) for your Shells and the Harbinger, which can be equipped whenever you rest at a Beacon.
Expect tough battles since the Desolate Keep is a mid-to-late-game area. Enemies down there have inflated health bars, shrug off normal stagger hits, and deal serious damage, so if you head inside when under Level 25, it will make the run way more punishing.
How to Commune with Chaos in Mortal Shell 2
To Commune with Chaos, you must have Slayer Seal in your inventory since you can’t interact with the chalice without it. You can get the seal from the stone throne in Marrow Keep. You might want to ignore this item on purpose because equipping it gives massive stat buffs, but it limits you from earning achievements. However, you only need the Slayer Seal in the inventory to satisfy the requirement; no need to equip it.
With the seal in your bag, head down to Sester Genessa’s resting place in Marrow Keep, located in the large underground chamber with stone coffins. Look across from her toward the southern wall near the shed structure for a stone block with a glowing white glyph. Strike the stone with a weapon to break the illusion and open the hidden antechamber.
Enter the room where you’ll find a stone pedestal with a metal chalice anchored to the surrounding walls by four heavy iron chains. Smash each chain with your melee weapon to break them, then approach the freed pedestal.
Interact with “Commune with Chaos” when the prompt appears to trigger the black mist ritual and teleport into the Desolate Keep dungeon, where you spawn in front of the water pool, with many enemies lurking around.
