Keep this inner ability as a BM or keep going?

Hey Thanks for the responses.

I currently have 30+30+20+20+15=115% boss atm. 50 from weapon, 30 from empress set, 20 from 2ndary, a15 from DS link

You're never going to get more than a boost of 235/215 = 9.3% increase in overall dps if you swapped in the highest tier %boss (20%). That is still a lot, but we need to consider what class you are, range, crit rate, the ungodly amount of (%)Att etc. you have.

edit: oh yeah, I remember I nearly cried when I reached level 60 IA. And pissed me of a lot that I only landed a 2%boss in 500-ish circulators. +1passive on a Luminous is really rubbish, though the rest of the IAs gave me >40 INT which is pretty decent. But still, wished I had a +1mobcount IA XD
