Where to Find the Mushroom Village Key
In the Open Beta, go to the Mushroom Village dancers gathered around the large fire. Find the unusual archway near them and pass through it to reveal a large stone monument. The key is attached to that revealed monument.
Short route from the dancers
- Start at the large fire where the mushroom villagers are dancing.
- Look near the rope bridges and the second group of dancers for an archway or gate-like opening.
- Walk through the archway. The view changes and reveals a large stone monument.
- Inspect the monument for the attached Mushroom Village Key.
Multiple players in the answered Steam thread independently describe the same archway and monument solution.
Pressure-plate interaction
One report in the same thread says the nearby stone pillar can be struck so that it slides onto a pressure plate. Treat this as a separate environmental step after revealing the monument, not as evidence that the key is sold by a merchant.
Do not confuse the two keys
The Mushroom Village Key and the Cage Key are separate. The Cage Key is associated with hunters at Grisha Camp and the caged Grisha Pup. See the Cage Key guide for that interaction.
This solution was verified against Open Beta player reports and may move if the final release changes the area.
