Flutes are weapons exclusive to the Commander class. They have lower AT, and medium AGI. High level flutes have strong damage, but Commander can't increase damage with SP. When the Commander equips this weapon, it will generate aura. When use Heal's Card, it can heal allies like Priest. The initial Flute and the LV 1-4 ones are simply called Flutes. LV 5-8 ones are Command Flutes which have triangle banner. LV 9-S ones are War Flutes which have square flag. Superior flutes have sub flutes' ability.
Note: Flutes can't composite Red and Yellow Crystal, and Explosion and Critical's Card (as same as Magician and Priest).
