How to clear the Mourner's Mile Spike Vault in Mina the Hollower

A hidden graveyard tunnel in Mourner’s Mile leads into the Spike Vault in Mina the Hollower.

Inside, players can grab a Vial Pouch and find a kear in a porous-stone chamber.

After exiting, activating the nearby pressure plate clears the spikes and opens the eastern route.

Clearing the vault unlocks the path to Queensbury Crypt and rewards useful progression items.
