After having fled up the stairs, and encountering a monster zoo down another stairs, I go back to the original stairs down and appear on top of an electroblobby and blocked by toxiblobby. I don't want to stand on an electroblobby. I'll try attacking and see what happens. EDIT: no game crash, I killed the blobby underneath, then killed the toxiblobby, and then the AI did me in
I have also in the new expansion with the teleporting levers appeared on top of traps, sigils of teleport and monsters. It feels wrong to stand on a monster and not get hurt, on a trap and not get hurt, on a teleport and not get flung to some hurtful place. All in one short Let's Play too.
If you move the teleportation blocks around, their counterparts teleport you to where the other block was. Whatever the area attack on the mace is, it moves around everything but the walls. Including, for example, viewscreens on the walls. It's kind of funny, to be honest. And really useful sometimes, too. And sometimes, I can block off stairways entirely.
