Thanks. Some great suggestions.
The reason asked: We are playing savage tides, just started. I know its a idiot build but for RP reasons and challenge reasons I am sticking to it.'
Samurai 5, Kensai 5 (comp.war), Exemplar 2 (comp.adv), Kensai 2, Exemplar 2, Kensai 3, Samurai or Exemplar 1.
Before any start...
I know Samurai are poor warriors with behaviour restrictions and fewer AND limited feats than either fighters or rangers without any of their perks.
I know Kensai are a false power class as tho they can boost str +8 untyped (as a move action) it only lasts 1/2 kensai level worst you cannot do it at will but its tied to increasing concentration checks, and is equivocal to the 3 bab you loose 24/7. The str is best used for a 2H exotic weapon and 1 level exotic weapon master so the samurai 2 weapon thing is limited further nevermind the pathetic d8 HD and lack of fort save or that monk and kensai are a vastly superior option.
Exemplar are just crippled.
That said the 3 classes fit really well together (perfection in action zen style).
I was going to go intimidating strike and boost intimidate but decided to just stick to concentration for my exemplar focus as it fits samurai duel stories better and the goliath barbarian has intimidate down pat nevermind a 1st level: +10 strength (+4 race, +6 rage). The dm gave the player mountain hammer proficiency for free so inevitably exotic weapon master and x2 str to damage shall follow so on the bright side any build I would make would be out damaged so the style and flexibility this build has will be more rewarding than trying to play damage catch up.
(we all got +1 ECL free as apparently its a hard campaign... thus my djinni bloodline)
As such I will have a huge concentration (which exemplar 5 lets you use as diplomacy like a jedi mind trick) and may as well use it to make up for any lackings in my build choices.
Again due to external reasons my race is raptorian. Goliath was sweeter with its save feats and all but one cannot control their destiny always.
Unfortunately Diamond mind and Psionics are off the cards. If only I could add concentration to damage....
