Feat to help concentration checks.

[Samurai]

I seem to recall reading a feat that gave you +2 on Concentration checks and also +2 AC on AoO resulting from spellcasting.

Now I can't find it anywhere. Did I imagine that or does someone recognize it and can point out the feat and what book it's in?

Thanks!

No - there's combat casting and warrior priest that helps with concentration.
And then there's a few traits that gives +2 trait bonus on concentration (which could be taken with the additional trait feat) - could you be thinking a combo of 2 traits?

Combat casting?

perhaps the dwarf battlefield caster trait? -- but thats only +1
