This last weekend I made the roll of a lifetime:
Our characters were sent by Perun, a Slavic god, into an area of Faerie to investigate why his powers no longer prevailed there. We discovered a valley, which was devoted to a different god, had been systematically ruined by violence and corruption. It now obviously had an infernal aura.
After retrieving the object of our quest, we got out of there. Toward the end of the journey, we began to hear eerie sounds of pursuit, and fled for the end of the valley. We made it back into the faerie grassland and kept fleeing... but shortly thereafter 20 mongol horsemen emerged from the gloom and charged toward us, raising their black bows.
My archer knelt and aimed. When they were in far range, he released his first arrow. I rolled a 1.
And another 1.
and another 1.
and another 1.
and ANOTHER 1.
and finally, an 8.
The storyteller simply smiled, took a moment, and replied, "Your arrow flies through the air, and grazes the neck of the lead rider. Blood fountains as the arrow buries itself deep into the eye of the rider behind him. This rider releases his own arrow, which strikes the rider next to him in the chest, causing him to topple off his horse. The body causes the two riders behind him to crash into each other, and break the formation of the other riders."
We faced the rest of the riders, and fought bravely. Some handy "Crystal Darts" and "Entrapping Vines" helped out, but all of us were wounded pretty bad. In the end, the remaining riders fled.
Whew.
Roll of a lifetime, though, I tell ya....
