It’s not all about buffing your team inOne Piece Odyssey, there are a range of debuffs to use in battles to hinder your opponent. While meals cooked by Sanji buff your team, it’ll be trick balls crafted by Usopp that will debuff the enemies during a fight. Usopp is the master of crafting trick ammo that has a negative effect on an enemy.

Whether you want to decrease resistance for a foe, or maybe rob them of TP to prevent them busting out the bigger battle abilities, Usopp has a trick ball for you. To use them when battling, simply select the item command and navigate to the trick balls. These are great to use on lower-level enemies, or minions, while bosses will often shrug off the debuffs with ease.
