Artorious, The Blighted Fang: Artorious is one of two offense-oriented summons that Bayle can conjure, a beast that uses the blade in its mouth to attack swiftly whatever his master commands him to. Being an attack-based summon, Artorious is able to dish out slashing, non-elemental damage, but this damage is comparable to a tank at best. It is not a summon meant for tanking nor DPS. Being of Bayle's summons, the wolf is able to buff a single target's attack power, namely used on tank or DPS. By expelling additional mana, Bayle can have his wolf use it's overdrive ability, applying an element to the target's weapon.
Alexander, Impassable Wall: To keep things simple, Alexander is a purely defensive summon, standing at 7'0', with high HP, that can tank damage, able to apply a special taunt to redirect attention. While the taunt works on Alexander, it can be applied to tanks, nearly tripling the effect, but this also acts to buff the target's physical and magical defense. Activating Alexander's overdrive causes it to apply a special buff known as Reflect that bounces back any spell aimed at whoever Bayle chooses.
Undine, Soothing Sea: Undine is a summon for healing and showing the force of water. Her main ability is using the soothing nature of water to provide over the time healing to those in close proximity or apply immediate healing to a single target. A simple task for Undine, for any attempting to target her, the aqua nature of her body lends to having a high evasion but, unhittable. Overdrive does not increase Undine's healing but instead let's her create whirlpool at the feet of a target, slowing their movements, and attacks.
Usagi, Hare of the Endless Storm: Usagi is second offense-oriented summon and Bayle's strongest....currently. Usagi wields the elements of lightning and wind to fight, etching itself as an off-DPS to help the main DPS. It provides an aura of lightning and wind to those in it's proximity, which enhances the overall speed of those effected. In overdrive, Usagi can use its wind to push and pull targets to move them around for a tactical advantage.
