With the range of Blood Lightning, I believe that Blood Light needs to have less damage based on how far you are from the target.
Either that, or shorten the range of it.
Mages are pretty overpowered since Warriors & Archers can't pierce their Defense at all using Lightning shock / Converting armor. GMSignpainter said this server has balance, but I believe the server is becoming less balanced than it was originally just for the mere fact, warriors and archers got a nerf to piercing abilities towards mages.
