Looking for the location of the boss in game

[Diggle]

Hi, does anybody know the spawn location of the boss Raezohr?

I think it can be in either of the cursed jungle cave or caverns of the lost dragon, but I am not sure on which floor it would spawn.

It spawns randomly on any of the 3 floors after jungle. I forget their name. It's years since I saw it though.
