Astras are non-combat monsters that provide boosts to the monsters on your team. They require energy which builds up during battles in order to activate their abilities. Each time the player activates an Astra's abilities, the energy cost for that ability goes up by 1 until it reaches 3. The energy cost does not exceed 3.
Astras can be leveled up through Divine Spores and gold. These levels are called "ranks." Each Astra provides additional boosts of the active skill for achieving ranks 2, 4, 6, 8, and 10. The Astra currently deployed will grant its passive boost. There are some game mods where you can't change your party astra during battle. During auto battle, the astra currently deployed will use its skill when possible (enough energy). NB : In auto battle, Suzaku will heal your team only if at least one member of the team has lost 20%HP or more.
