Talk:Empress Boa Hancock Kuja Pirates Captain/@comment-31777595-20180124151017

It is normal that I give her 5 copies during the lvupx2 and she got just one level (this happened twice) and when I give 5 copies to Magellan he gets 3 lv ups? The lv up rate was so good lately that I thought they increased and then I was so unlucky with Boa. Is the lv up rate linked to stamina, rarity, utility or anything similar?
