Iron Dimensional Door: Placing one in the world will create a new and empty dimensional pocket, a black void in which you can build whatever you want: a small house, a statue, a farm, a huge base, or even a whole city! In dungeons, it will typically lead back to the previous pocket, but sometimes a second Oak Door in a dungeon will lead back to the dimension where the player first entered this chain of dungeons. Oak Dimensional Door: Easy to make, but not very useful. A dark, foggy, and mysterious dimension filled with monoliths, where players who died or tried to cheat in a dungeon end up.
