1 = empowering bad people (through rituals, creating agents of chaos)
2 = Little Hell Gate (open a mini door, and release weak demons across the world)
3 = mind control
4 = possession
5 = make dreams come true (for example, creating a snake in someone's dream and bringing the snake to reality)
6 = take souls out of hell and put in new bodies (for example, take the soul of adolfo mustache and put in the body of someone alive)
(my favorite) 7 = to be able to give an "evil system" to someone, (eg kill 10 people and earn 1 million dollars)
