Aeroga III can be learned by Black Mages at level 67. Aeroga III's scroll can always be purchased in Lower Jeuno from Susu. In addition, its scroll can also be obtained as a drop from high leveled Yagudo enemies.
Aeroga III scrolls can also be possible rewards from Campaigns in the Shadowreign version of the Sauromugue Champaign, however due to low amount of players participating in the Wings of the Goddess events, obtaining it this way is ill-advised.
Aeroga deals Wind-elemental damage to all enemies with range. It takes 7 seconds to cast and can be recast every 25 seconds.
Aero is a Greek prefix relating to air and flight. Common usages in modern times include the words "aeroplane" and "aerospace". The "-ga" suffix denotes it is the level three form of the base Aero spell.
