Well I don't know the answer but I have another question that hopefully someone has knowledge of. (I can't make my own threads yet it seems)
Supposedly these are stackable but when I add one to my active slot and hit a battery, I get a 10 DPS boost (yes 10) it shows. If I add another it give a minor addition to that. With all three my DPS goes from 550 per cannon to 580 or so.
Something has to be wrong here? If it hit just APO1 with 15% boost my DPS goes to over 630. Clearly something is not right.
Anyone have any insight.
Thank you kindly for your time. And if someone could answer the OP question that would be nice too.
