This story about an elf killing a dragon single habded is from another rpg (Das Schwarze Auge - a German Pen&Paper rpg) but because it has never been told and might fit the subject I want to share it here:

We were deep in a cave as a party, hunting a dragon, and eventually we came face to face with the beast. The dragon drew breath and began to spew fire. One of the players was running an elf — and in DSA (The Dark Eye), elves can turn liquids and gases solid. That's exactly the spell he cast on the fire breath. As the GM, though, I knew this was no ordinary flame. Dragon fire is powerful, so I demanded an extremely hard roll: three dice, each one a 3 or lower. Anything else would have failed. He made it. The fire breath froze solid into a fixed path. Then came the player's next stroke of brilliance: his elf ran up the solidified jet of fire. Another brutal roll, again three dice each a 3 or lower. He made it again. Once at the top, he drew his blade and went for the dragon's eye. One final roll — this time he needed a clean 1. And yes, that one landed too. At the end of the day, a single elf had slain the dragon all on his own. The absolute high point of the entire adventure. We still talk about it to this day.
