Overview
This is a guide showing everyone the scope of each dungeon and worker theme, for you to be able to make up your mind.
How this works
What i’ve done is screen shot captured the overall theme for the core, the tiles, door frames, and the worker skins. For workers without a dungeon theme, they are in a collection together.
Arcane
My personal favorite, this theme is unlocked by completing all Bonus My Pet Dungeon achievements.
Evil Arcane
Originally this was unlocked by those who had the game during early access, but now it is unlocked by completing each Undergames Level on the Master difficulty. They do not have any special worker skin, and use Oberon’s workers.
