In the Advance and PSP versions, Jump can be upgraded to Double Jump by equipping the Dragoon Gloves. Double Jump does double the damage of a normal jump, and Kain comes down 25% of the time. Double Jump has a Charge Time of 5.
Double Jump is a Band ability that allows Kain and Ceodore to attack from the air simultaneously. It is one of most powerful two-person Band abilities, able to break damage limit without a Limit Ring. Double Jump can not be performed once Ceodore uses Awaken.
