Most of these spells are forbidden with the penalty even being death because of what they could do if released into the world. 1. Righteous Killing- a spell created by the angels in order to take out the heavy hitters in the Devil faction. This spell requires four different items. 3. MDD (Mad Dog of Darkness) Spell- The spell has the ability to infect the heart of a hero and turn them into a wild rampaging like animal.
