Method to Acquire: He starts off in the top left hand corner of Chapter 8 with Wendy and Ojay as a playable character.
Damage - Barth's damage is very good, he'll be getting strength more often than defense..
Critical - It can be high if you get him supports and perhaps a Slim Lance, but it usually won't be otherwise. However, a triangle attack gives a first hit to be an auto-critical.
Speed - It's not good at all. Wendy and Bors easily outclass him here.
Dodge - His dodge is terrible, but then, it doesn't need to be high. He probably won't be taking damage from any units with the possible exception of magic-wielding units.

Rating: 8.15/10. He's usable in Normal since you have more character slots, but later on, all the Generals are better then him. In Hard Mode, he's a very good wall but Bors usually has high armor as well. Not as good, but enough in my opinion.
