My favorite and most heroic death was a character I played in Red Hand of Doom back in 3.5
The GM was awesome, the players were awesome it made me look forward to each game.
Character
Vandraven Elf Rogue / 7 I think
My rogue had done a lot of dumb things throughout the campaign due to me being new to the game and the character I played was a fast talking thief. Needless to say I ended up at -9 three different times. One time it was due to putting on a clock with a flame pattern I won at a carnival of Nurgle, we had as a side quest/break.
My characters main clam to fame was killing a goblin shaman and a worg at level two through the use of terrain and tricks.
Our party hears of the Red hand army moving through the mountains near by. There’s only one bridge crossing. Without the bridge it adds another week or more to the armies travel time. My group decides that were going to destroy or hold the bridge to buy some time for people to evacuate.
When we get to the bridge our group takes out a scouting party of hobgoblins and ogres. It’s a tough fight but we pull it off. Vandraven climes up one of the bridge towers and looks around from the roof. Here comes the army of the Red Hand. Oh and a giant black dragon.
The dragon doesn’t see Vandraven so he does a strafing run on the rest of the party with his flame breath. Everyone but Vandraven and the Wizard panic and run back across the bridge.
Vandraven draws his sword and yells to the wizard to finish the bridge. The wizard starts to finish the setup to blow the bridge.
The dragon hovers over the wizard about to breathe fire again. Vandraven leaps off the of the tower and crits the dragon for max damage (DM said I took out his eye ;). Through very high reflex saves Vandraven grabs the dragon by a horn and stays on him.
The dragon is furious and the wizard blows the bridge. Vandraven goes two more rounds on the dragons head scoring one more crit hit with his longsword two handed before falling to his death in the chasm.
