As title suggests, I was just wondering what sort of situations you've plunged yourself into, on purpose, outside of the normal bounds of the game. For the most part, I'm not talking about restrictions you place on the game yourself (unless they're particularly interesting!) but situations that arise during play tha are unusually dangerous to you and you attempt anyways.
For example, I was recently playing a Dwarven Priest that would eventually YASD to a greater dragon vault (1.2.0 - sage = what hp warnings? = distraction dead) that had the misfortune of having the only Fireproof Blanket he had generated burn up prior to the ToEF, and didn't acquire a single Ring of Ice. Rather than take the boring route of farming for another one and/or a Ring of Ice, I attempted the tower without either, equipping lesser non-fireproof items and leaving my 7LBs behind, along with all of my inventory except a small handful of lizards/stoma, a pickaxe, and a couple slings and rocks. I managed to beat the ACW with just that, after two wishes for pickaxes (second was accidental, but my pickaxe had burned prior to the top floor), 2+ wishes for health while fighting him, and a long drawn out fight involving praying for luck on my bolt spells (my ranged weapons that i brought burned too, all 3 of them) and trying to out damage his regeneration with rocks/minor punishment. Was a blast though!
I know I've had other situations occur, but that's the most recent one that came to mind and made me want to start this thread.
So anyone have any interesting situations they'd like to share?
