Eva's Knight Lionel Hunter:
I'll tell you about the fifth test.
First, you must reach Lv.105 to prove that you're qualified to be Guide of Power. You must also 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. If you forget who you must go to, refer to the guide I'll be giving you.

All this can be substituted by completing a mission from Cardinal Seresin in the Town of Oren.
"I'll do that."
