Not sure if it will make you feel any better, but my worst death:
Nice char (hobit monk, iirc) going for ultra. Got everything needed for ultra, nice quipment. On d49.
Put on chaos medal and crown, but still need 5 or so corruptions. Start quaffing potions of raw chaos.
First (or maybe second) corruption is blot the sun -- I did consider lighting torch, but well it's few sips.........
I don't believe i've left d49, but maybe i hit <>(i doub it, might have moved one square)... Well, if you ahve not guessed yet...
Corruption kicks in darkness, char is doomed due to chaos artifacts, grues were waiting.
So far rolled 15 casters with RoDS and shamelessly killed them within 200 turns. For eternium glory!
(after 15 I stopped counting...)
