Ive heard the backstabing effect on one of your weapons grants the bonus for both weapons. I was wondering if anyone knew if the seeker weapon bonus transfers to both weapons as well?

Does any one know if there is a weapon stat guide that has specifics on stuff like this? im guessing the backstabbing effect is the only effect which transfers but am curious as to other things like cursespewer, paralizers, destruction, rightousness, radiance weapn effect, deception, etc etc.

Thanks again for your help.
