Yeah, must be a bug then. Not that I care about missing two more shots. I'll end up sticking with swords for most PvE stuff and Spindle/ToM for the raid.Well that's really strange. Nami can't seem to get past the 7 max either. But I'm currently at 9.
I'm using some random Rare boots I dropped somehwere. It's not the "Increases the amount of X ammunition" but "Carry more ammunition for X", maybe there's a bug?
