4th job Single Target DPS

But you can blind a boss. I love heroes.

Anyway, final attack does charge orbs separately and is triggered after the attack. Not sure what else you need to know about heroes, it's pretty straightforward, except for critical which I've explained already. (+100% from advanced combo @ 30 + 120~50% normal crit, or +110% @ 32 adv combo, etc)

If you have time on your hand, you might want to add in combat order for every class to see how beneficial it does to each, just a suggestion.
