IN THE HEAT OF BATTLE...Edit
Earina boasts almost all of the same statistics as Chamiluna. Both are weak in Strength, Wisdom, Vitality, and Spirit, but their Speed is beyond that of all the other Maus in the game. Its signature magic, Sadoon, is an S-Rank Wind Magic which can nullify the resistance of all Divine Beasts on the BeastAmulet, leaving it open to Sudden Death-inducing moves such as Ad Mumarnite, and sleep-inducing moves like Ad Slahnit.
Chamiluna is covered in detail here.
