Thank you for the welcome, I do agree that as I re-read the class after dusting my books you are quite right, probably confused the CW one with the OA one. In any case as I saw both your and HMs posts, ideas on background kept popping in my head, so I'd like to stick with his concept, a son of a disgraced samurai who tries to regain the honor of his family and find the ancestral swords of his family.
I'm seeing him as a pure martial character and I saw him maybe working towards a "samurai like" PrC(I'll have to check what that would be eventually) but I've never been one to optimize a character. Seeing the concept I figured that 2 classes could fit well as a base to jump to a samurai like PrC, knight from the PHB2 or the good old fighter. The only thing messing the concept up the fighter class would be the class skill selections as samurais were trained in etiquette and poetry from a young age. What do you guys think?
Well for what I'm trying to emulate is the honorable defender of his lord/adopted people. I also want him to be close to an historical representation, wich means less katana focussed than what you would otherwise see.
Samurais were masters of many weapons not just the sword, although it was an important part of their gear, so was the bow, spear and other various weapons. I think the knight would be the best fit.
