How Do I Defeat Jedah?

Jedah's nullifies the effects of your attacks; however, these nullifications aren't exactly random. As the seemingly crazy guys back in Sage's Hamlet hinted at, every fourth round of Combat against Jedah will land successfully. Because Jedah has some fierce counterattacks, you don't really want to do this more than you have to, so try to make your first successful attack the only one you need to take him down.
