Shenron is a profession that is quite difficult for exp due to mana problems and the fact that his strongest spell is quite weak to exp which forces him to use worse spells. He has a pretty good dmg of ki on target spell and a good dmg melee which is further increased by "omega blow", which for a certain period of time gives him a 100% chance for a crit, which in combination with his dash to the target makes him a real killer who is not easy to kill.
