- Trial Chambers: The biggest feature that ties everything together, you can locate the Trial Chambers via looking for a windmill like structure on the surface made up of copper. Breaking the Oxidized entrance will lead to the entrance of the Trial Chambers. These chambers have there own unique rooms, randomization, and unique every single time. They also have the chance of generating encounters, which are like smaller chambers. Additionally, these chambers are better than vanilla in the amount of chambers generating. You'll usually get 3-7 chambers per trial chambers while vanilla can range from 1-5. There are also custom rooms not found in vanilla that fit well with the theme!
