> Chain Attacks. Chain Attacks can be used after the Chain Attack gauge, shown at the top left of the screen as a bar, is full. The gauge fills after dealing damage or taking damage. When you initiate a Chain Attack, each character gets to use any one ability they have, for a party total of 3 attacks. However, it is possible to continue a chain attack, adding on more attacks. 
More on Bonus Chain Attacks tomorrow.
