Kizuna Rush
One Piece: Pirate Warriors 3 contains a new mechanic called the Kizuna Rush. Unlike the stylish support players were able to obtain in Pirate Warriors 2, this rush allows more than one character on the screen as the player opens up a can of Devil Fruit infused violence upon hundreds of unsuspecting opponents.
Filling up the meter will allow players to summon their selected support character (up to four characters as you advance) to fight alongside you. You are also able to trigger a powerful combo attack using all of the fighters that essentially clears the screen.
The Kizuna Rush is perfect for overwhelming crowds that not only have grunts (weak pirates and marine foot-soldiers), but captains and special characters, as well. Make sure to fill up your Kizuna Rush as quickly as possible by using variety in your attacks and going for large combos. Keeping this ability in your pocket will definitely help out when facing near impossible odds.
