Combat Styles are one of 3 main ways to deal damage in Universal Piece.

There are 3 different Combat Styles in the game. You will start off with the default Combat Style but you can buy a new one in the mid and late game.

When you acquire a new Combat Style your old one will be removed from your inventory. However, if you want to switch back to the one you already had, you will need to go to the NPC that sells that Style and just get it there (You won’t need to buy the Style again).
