question about kensai critical perfection

[Darkdux]

Hi everyone. I have a question about the magus kensai archetype: at 9th level, i gain Critical perfection, but i cant' understand what the description of this feature intends as "prerequisite": the base attack bonuses or the critical focus?

At 9th level, a kensai adds his Intelligence bonus (minimum 0) on critical hit confirmation rolls with his favored weapon. In addition, the kensai may use his magus levels in place of his base attack bonuses to qualify for Critical Focus AND any feat for which it is a prerequisite; these feats apply only with a kensai’s favored weapon.

This ability replaces the magus arcana normally gained at 9th level.

So the Kensai uses his Level as BAB when it comes to the Critical Focus Feat and any feat that has Critical Focus as a prerequisite.

So for instance; Bleeding Critical, Blinding Critical or Deafening Critical among others. All these feats have the Critical Focus Feat as a prerequisite, therefore, the Kensai can use its level in place of its BAB for the BAB prerequisites on these feats.

And it only works on his favored weapon.

Correct.
