ok, i've finally remembered how to make bow strength work, they changed it sometime in 2012 and i didn't notice because i had a zen archer at the time. altho it is a granted feat and should work, you have to meet the prerequisites. after you meet the prereqs you'll receive your strength modifier for damage that stacks with all other bonuses. this is as it should be and how bow strength works. it's not a stat swap if higher feat as many newbs would try to tell you.
it never was a swap feat.
to meet prereqs i take combat expertise and weapon focus ranged.
now, where the hell did i mule my gloves of titans grip..... (+6psyonic bonus to str / ~1.5min)
