Zaitoichi, Blind Swordsman
Wow, here I was just crusing the boords on my daily rounds, and thinking about creating a OA character based off of the popular japanese films about Zaitoichi.
Zaitoichi, for thoose of you unfamilar with the films, was born into a late Tokugawa era samurai family. He was born blind, but he learned the way of the sword anyway, and was a damn fine swordsman.
Now, Ichi wasn't much better with his sword than any other well-trined samurai, that is to say in game terms he and another hero would have equivilant BABs and such. What really made him amazing was that he could fight so well blind.
That said, there is many a scene where Ichi will slash and stab at empty air... Of course, in a samurai drama, fights are one-on-one, and only involve what woudl be in game terms low-level humans.
I think your PrC preserves this feel, but in a world where you go prancing through dungeons, battle oddities like Ogres is routine, and the guy in the funny hat next to you can cause an explsion with a small ball of guano and a funny soudnign word.
Kudos, I'm stealing this...
