Esoda (Mylan Island, the main city of Delaney)

There are three things:

Fort Glory (Hellfire Peninsula, in the hotel)

Shacheng (there is a small room on the right of aldo Heights, just ask the guards).

Storm spire (netherstorm, the camp of the Star Consortium)

Esoda can only learn up to 300, and three outlands can learn up to 375.
