Another new feature within dungeons is the ability to randomly go into another dungeon when you access stairs.
This only happens after you complete the game and Dungeon Switching will send you to any of the non-DLC dungeons.
This change lasts for a few floors and when you return to the previous dungeon, you will be at the floor equivilant to how many floors you missed there.
So for example, if you left the first dungeon on the 4th floor and were gone for 3 floors, you'd return on the 7th floor.
