The game also has similar gameplay to the Final Fantasy game. The screen will switch to the battle mode when a battle starts. Enemies will be displayed in front of the screen opposite to the characters in the game. The battle will take place in the familiar Turn-Base style. If one team is completely destroyed, the other team wins. In addition to the characters using weapons to cause physical attacks, these characters can use the special skills of the devices. All character attacks are calculated using AP points. The character will consume AP points depending on whether the attack is strong or weak. At early levels, a character can only use up to three AP points per attack. However, each character can use up to 7 AP points at higher levels.
