Larian Studios Forums Beyond Divinity (English) Help/Tips/Tricks A Question About The Yellow Baffimiri Mushroom

I'm down in the dungeon that has the mushroom.The problem is I've come to a room with a locked door.I can see beyond the locked door,that there is a ground lever,but I can't get in there.I picked up the key in the room behind the wall,but it doesn't open it.
Thanks in advance.

After you get a crystal fragment things will happen and you will wind up on the otherside of a door you cannot now get past.

There is a locked chest west of where you found the key...
