It would be kinda cool, but as it was I was terrified of being stuck in there even when I just 'thought' the stairs could be destroyed. I'm still wearing all plains-tier gear, and the mistlands is kind of terrifying. Those seeker warriors are no joke (have not died to one yet but the 1-star one I ran into was no joke).

On the up side, this infested mines has been great. I got 18 of those dark cores out of it already and I haven't even explored the whole thing yet. Stopping to use my pickaxe on the two stairs where I was, to get more marble. I didn't want to kill dvergr so I didn't have any of that yet.
