Since the other thread is dedicated to bad players and is a bit off track, here's one for the cool ones. Or, hey, post about awesome things the characters have done. Blow your own horn too. I'll start off with some self-proclaimed awesome and bring some more fun from people who aren't me later.
Fun With Dragons and Saving Throws
Our campaigns always edged towards epic, manic and just plain wild. The standing rule to any potentially crazy choice was "DO IT". Our characters were somewhat overpowered, so they always ended up not fighting just one dragon, but several. All of these were years ago, so I'm fuzzy on exact details of WHY we were doing things. Ultimately, I'm fairly sure it didn't matter.
All of our characters were on an airship that was suddenly beset upon by two dragons. We always played with a bunch of mixed levels ... some were level 6, others 12, and a few 18 or 20th level characters. The high level characters all grouped up and flew off the ship (yes, they all had flying abilities at this point) to deal with the larger dragon, leaving the lower level characters to protect the ship from the onslaught of the younger one. After several fly-bys, my character finally grew sick of having to hold his action to attack when it rode by.
Bear in mind, this was (to my current horror) a Drizz't Clone who wielded two katanas and wore a cloak not unlike Spawn's (chains and all). My DM was crazy enough to give me what he called an elemental sword. Once per day, it could do an ability based on each of the elements. Air, fire, water, earth. My drow (God DAMN it) leaped from the airship and clung to the back of the dragon. He started making swipes along his back, trying to get rid of me and flies above the airship. Knowing he can't possibly kill the dragon by himself, he makes a last ditch effort.
Self: "Alright, I'm going to try stabbing the sword into the dragon's back."
Dave: "Make the roll."
Self: "Stone to Flesh!"
Dave rolls for the save and gets ... a 2.
"You did it. I don't know how, but you did it. The dragon's scales slowly begins to petrify around your sword."
Dave: "You suddenly realize you are on top of a slowly petrifying dragon. It struggles but is finally no longer able to flap its wings. The heavy weight of the stone dragon now plummets and crashes through the airship, splintering it into pieces. Everyone on the ship falls into the ocean below. The rest of you fighting the other dragon see the ship explode into pieces and Riensynn on top of a giant dragon statue, surfing it down, as he suddenly disappears into the ocean."
Dave: "Do you know how to swim?"
Edit: Aware it's kind of jerky to create an "awesome characters" thread and post yourself first, but it was the shortest story I could think of at the time.
