Pirate Ranking Trophy in One Piece: Pirate Warriors 4

Action Growth Levels are found in characters' Growth Map 1. They are represented by an arrow pointing up. Action Growth Levels unlock additional combos and move-sets for your character to use in episodes. For this trophy, you only need to max one character's Action Growth Level. Simply find all islands on the Growth Map with Action Growth Levels and max them out. You will know it is maxed out when the icon turns gold and has a crown above it.
