Area Bosses - Which is which and how to find them

Zeno spawns at "Hidden Street : Gray's Plain", however this map in GMS has no name. It's accessed from pressing up on a rock on the upper level at Kulan Field 4. has no skills, but he makes up for it with the raw power of Super KB. It does about 650 damage, but you can jump to avoid it, so it's not too much of a problem. Still, since it's his only ability, he uses it quite a bit. As I recall, Zeno drops some pretty nice scrolls, but since he's in Omega Sector I doubt he will be hunted often.

Oh really? That super KB deals 150 damage to me. I have 300 weapon def and 290 magic def. Also, touch damage deals 100 to me. I don't see anything that deals 650...
