As I previously stated already I ended up quite liking that character, wouldn't mind having it on my team. His Shadow Strike seemed quite good, looks badass too.
I died for the first time at the 7-10 boss battle and then again once in 8-2, enemies are getting tougher and need to start paying more attention. Would love to get Grace's second job to lvl 15 to get her area damage skill; should have that in 2 more Metal zone visits.
Once I beat chapter 8 and get the next daily bonus I'll be able to get another new character.
