The trial chambers I'm assuming should be fully submerged underground, but they stick out like a sore thumb in caves and it looks pretty ugly. I also feel like the entrance to the chambers (the copper barrier in the entrance room) should be the only thing that connects to the caves, that way if you're exploring in caves the only way to enter is through the trial chamber entrance. I don't know if thats actually a bug, but thats how it should work.
