Clans Lv. 5 or above can found an Academy.
You can enroll in an Academy if your main and subclasses are all below Lv. 85 and have not Awakened. If an Academy member Awakens, they automatically graduate.
Up to 20 members may enroll at an Academy. The amount of Reputation a clan receives when a member graduates varies depending on the member's level upon entry.
When a clan founds an Academy, its clan leader gains buffs for the benefit of the members.
Academy members can use their Academy Circlets to efficiently power-up their character.
The leader can appoint a clan member to sponsor an Academy member, which gives the sponsor buffs to use on the sponsored member. They're a bit weaker than the clan leader's buffs, however.
In addition, sponsors can help their partners carry out Academy quests, and check their login status.
Academy members can do Academy quests with their sponsors at Lv. 70. Upon success, the clan, sponsor, and Academy member are all rewarded.
