I have two...
Val'ynar Hammer of Ancient Kings and Verigan's Fist. (Yes, that one from the Paladin lvl 20 quest. You can't get that one anymore.)
Some weapons were cool when they first came out, but since the game has gotten more and more hi-rez, they look worse and worse... I'd like to see updates of the Warrior quest weapons like Whirlwind Axe.
