Air Battle System

After the group gets the Rheairds, they can participate in air battles as well as land battles. When they use the Rheairds to fly from town to town, they can see enemies in the air that they can fight. However, a character cannot fly a Rheaird and fight at the same time--thus they double up on the Rheairds. There are four Rheairds and nine characters. Dhaos and Arche can fly on their own, while the seven can double up on Rheairds. The player can choose which two are on a Rheaird together, or who's on the lone Rheaird. The player can also place Dhaos or Arche on Rheairds if they wish to. The person on the front of the Rheaird flys it while the person on the back of the Rheaird fights. Essentially, the player controls two people--the driver, who can go in all directions around the 3D battle field; and the fighter, who fights, uses spells, and uses items.

Doubling up characters that like each other gives them stat boosts while they're riding a Rheaird together. The affects of the stat boosts depend on the characters doubling up together. Story events, leveling, and the affection system can change who likes doubling up with who and what stats are boosted.
