I'll keep a record of my dumber deaths here.
Just now my Grey Elven Priest Carari died from a writhing mass of primal chaos. Damn, first I stepped into two corruption traps just a few paces away from eachother - then this? On level five of the Mad Carpenter dungeon, aswell. Madness. I who just had found a neat blessed weapon and a hexagonal key.
Two deaths before that, a stone block randomly hitting me in the head instantly killing me. And there's always the good old "you broke your leg kicking a wall" - also instant death.
