Unearthly Dagger

undefined The Unearthly Dagger is an item in Immure.

Description
"An Unearthly Runed Dagger."

Location
It is located in the left area of the unnamed hallway Will is transported to after finding the Shining Trapezohedron, but only after Will uses the Strange Key on the locked door there to trigger a number of changes in the hallway. It is initially locked in a cage, but after Will stuns the Nightmare creature and exits to the right, he emerges back at the left side near the dagger, now accessible.

Use
It is used to kill the bipedal head-eater after stunning it the second time.
