Berserk Charge is an ability that appears in Kingdom Hearts II and Kingdom Hearts II Final Mix. If enabled, this ability prevents Sora from using his finishing move while in MP Charge, which creates an infinite combo until MP is restored.
Berserk Charge uses 5 AP to equip.
When using Berserk Charge, you cannot use a finishing move to kill the majority of bosses throughout the game (including Sephiroth, Xemnas, or many Heartless bosses). This is because they have a variation of Once More equipped that forces you to kill them using a finishing move. However, this can be advantageous, as it can be used to deal massive amounts of damage to the boss until a finishing move is necessary. Sora can also use Upper Slash (ground) or Horizontal Slash (aerial) attacks to finish off an opponent during MP Charge.
