So I was on the second floor when a Transdimensional Dodge kicked in and my poor eyebrowed hero found himself trapped inside a wall that should be opened by a lever - only it hadn't been opened yet. Knightly Leap was unable to free him from this mishap and he was forever imprisoned in the walls of Dredmor. I fear this was an oversight by the dev team. A small one, and too silly to be mad at. He was saved from a monster zoo he had no chance of defeating. Either way my game was over. XD Just thought the guys at Gaslamp might like to know about this if they didn't already! =)
Odd, other teleports let you teleport or at least walk one way or another. this is where spacial potions are most handy, random blinks are amazingly useful a lot of the time.
I got stuck in one of the one by one rooms with no way out either because of Transdimensional Dodge too.
