Eva's Knight Lionel Hunter:
This is the third test.
You must overcome not just the limit of the power you were born with, but also the limit of the new power you obtained.
Make sure your Dual Class also reaches Lv. 100. Then, go find Merlot in Hunter's Village, Captain Kurtiz in the Town of Aden, the Blacksmith of Mammon, and Sir Gustav Athebaldt in the Town of Oren, and pass the tests they give you. It's best that you hear about the tests from them.


Remember to bring back their certificates.
If you forget who you must go to, refer to the guide I'll be giving you.
