Weapon focus does not update for being a Kensai. It continues to use the regular magus weapon focus which gives fewer fighter levels. Knowledge pool is removed (as appropriate).
In this example the character does not qualify for pin down, even though he should have 13 equivelant fighter levels (8 from level 11 Kensai and 5 from fighter).
Also it appears to be counting the levels that it does count to give bonus fighter feats (the character should have 3 fighter feats at fighter level 5 – but he has 6, which is what he would have at fighter level 10).
I've read this issue five times, and I really can't fathom what the problem is. What is Weapon Focus not doing?
"At 1st level, a kensai gains Weapon Focus with his chosen weapon as a bonus feat." this is simulated by allowing you to take Weapon Focus.
Nothing seems to be incorrect for "Weapon Focus". The Magus Fighter Training seems to be the source of your mysterious feats increase. "Pin Down" was incorrectly coded.
Sorry. It didn't make sense because I said the wrong thing...
I didn't mean weapon focus, I meant the magus class ability "Fighter Training". The Kensai version is received earlier and advances faster. I was having the problem not just with Pin down but with other fighter-level-prerequisite feats (e.g. critical versitility). The level 11 Kensai / 5 Fighter should have 13 fighter level equivalent.
Any other fighter feats that aren't being qualified for, please post them here. I'll fix the ones that are brought to my attention. Your other issue has been solved.
Nevermind, any from Advanced Race Guide was mis-coded, those will all be resolved.
