Creation Process

Cursed Spirits are created when pain and suffering leaks from Non-Curse Sorcerer Humans and the Death Energy of a Few People. This Stuff gathers in one spot, building up like sediment until a Cursed Spirit takes form
Curse Sorcerers must also be killed with Magic/Curse Techniques or they can become a Vengeful Cursed Spirit after Death
