Eva's Knight Lionel Hunter:
You haven't finished all the tests. In order to become Guide of Power, you must pass all the tests.
You must reach Lv.105, pass the tests of the following people and receive their certificates.
The testers include Master Cyphona and Quartermaster Dinford in the Blackbird Campsite, Owner Settlen of Underground Gainak Mystic Tavern, and Admiral Keucereus in the Keucereus Alliance Base.


Only they know what they'll test you on, so go talk to them.
