DM: "Black Dougal, you find out that you missed a tiny discolored needle in the latch. Roll a saving throw vs. Poison, please!"
Dougal: ***rolling*** "Missed it!"
DM: "Black Dougal gasps 'Poison!' and falls to the floor. He looks dead."
Fredrik: " I'm grabbing his pack to carry treasure in."
I love it.
