Realms have been finally added these are a BIG part of this game, and have been in the works for a while, realms are like side-dungeons /worlds which can be accessed from different Normal dungeon levels, these realms, are also randomly chosen for the dungeon so each time you play so you get different realms on different levels, each play-through , and armor now changes your color, and new weapons and enemies added (for the realm) , realms play by different rules then normal dungeons, depending on the realm-type, they can be misty zombie apocalypses in a different time period for example. (all still procedurally generated)
Note the completely different style this realm has from the dungeon, the most obvious being that the background is blue due to mist, and that the ground is much bluer, the world is more mazelike.. and many other differences (like human zombies, HUMAN zombies dont exist anywhere else, right now, though there are goblin, bat, wolf etc. zombies in the main dungeon.) This realm is more horror-oriented then the main dungeon, trust me.
