Overriding the BAB of a character.

[bodrin]

I have a weapon that uses it's own BAB instead of the characters.
I've tried to set the wAttBAB and the wAttack fields respectively but cannot figure out how to negate the BAB of the created hero!

The rod uses its own attack bonus (+12) rather than yours, and each attack deals 6 points of bludgeoning damage. Treat the rod as a magic weapon for the purpose of overcoming damage reduction.

Any ideas how to do this gratefully recieved!
