How does Hakus fan affect my stats? I get that potential gets carried over to the character, not weapon damage... which is really OP. But what about other stats on the fan? Like a Zakum poisonic fan or a Faf fan which have 10% boss and PDR, respectively. If I equip the same fan twice, will I get double the benefits? (Quick question: Which %s stack additively and which stack multiplicatively? ._.)
