It amazes me sometimes how much the dice actually do follow awesome narrative possibilities.
So we were fighting the big bad boss. And
thespooniest's character summoned a cosmic nasty, attempting to piss it off while imitating the boss we were fighting. But he forgot to state exactly who he was (or who he was pretending to be), and the result was that the cosmic nasty turned up and was generally pissed at everyone in the room, including our party as well as the boss we were fighting.
It attacked me first. If it had hit me, our DM would have had to do some pretty fast talking and DM-ish contingency planning to keep my character from dying. But it missed, just barely - I saw the dice roll myself. And there was frankly very little chance of it missing me.
Then it attacked the boss. Critical hit (the DM rolled a natural 100 on a d100, with the system we were using - and again, I saw the dice roll myself), killing the boss. The death of the boss triggered the appearance of the escape route, and our party ran for it. Tadaaa. Lots of EXP to go around, all of us mostly unscathed.
The chances of this were phenomenally small. But it happened. And I realized that I've seen stuff like this happen more than I've seen it not happen, when it was possible. More often than not, completely awesome things will come from real dice rolls. What the hell.
