Seems pretty damn generic, but I like that he started as a slave. Wish he would really have to claw his way up, but of course he's going to rocket through everything. I really hate the "I have an ability that makes this normally mundane thing really overpowered" kind of tropes. It's textbook contrived writing and just takes away the agency of the character's progression. Like, "you're only strong because of your lucky ability" kind of thing. It gives me the same vibes as exploiting a game.
