Method to Acquire: He arrives with Wendy in Barth in the top left corner of the map as a playable character.
Damage: Ojay starts low, which is to be expected, but he gets better and deals high damage later on.
Critical: Ojay has an average of 11 Critical without supports or a Critical increasing weapon.. Not that you will need him to critical.
Speed: He'll get quick enough to hit twice pretty fast. If he doesn't max speed, you got very unlucky.
Dodge: His dodge is EXCELLENT since he has high speed and high luck. His average dodge as a level 20 Hero is 78, which is more than good enough.

Rating: 8.35/10. He's a good Hero, definetely better then Echidna, but his biggest problem is his low level at that point in the game in Hard Mode. My Dieck was already a level 1 Hero at this point and for this reason it's really pointless to raise Ojay.
