It's really baffling/dumb that there are not more people/invented ways to check skills in the world. Or, minimally, a person/people who study a person to determine unknown skills.
You'd think that a person given the title of Hero would be studied rigorously in hope of producing more heroes.
Also, what arbitrary rule gave the fukboi the title Hero? Was he a noble? Or was he just the loudest? You'd think a party would be given the title, not just one schmuck.
