So I'm going with a human for the extra feat. I'm using Kensai for all lvls but lvl 3 so I can have my black blade. And in using ascetic style to get panther style, strike, and parry.then working on getting ascetic strike. My gm has allowed the urumi, as a monk weapon as it is in the fighter monk weapon group. So including improved crit I'm looking at 2d8 (15-20x3) at lvl 20.I also plan on being a lich, but I just wonder if I'm missing something....any pointers?
Without more detail, its hard to tell if you're missing something. I'm not sure I understand what you mean by kensai for all lvls but level 3...kensai and blackblade don't interfere, so really you are playing a kensai blackblade magus for all levels.
For the build - do you have a good wisdom for the panther claw attacks? Why do you plan to provoke a lot. You still *also* need improved unarmed strike for all this ... why not just take the flamboyant arcana option if you want to make extra attacks?
