Magic

Magic is a mysterious and powerful source of supernatural power in the series Supernatural. Magic can be utilized by different types of spells (ex. Rituals or Incantations) or through using specific unique supernatural powers/forces/energies. Magic can also be infused into objects and certain events have magical properties. It's a common reoccurring set of powers and/or skill sets in the series.

Natural Order
The The Natural Order in and of itself is magical in nature. It dictates the universal aspects of reality. Even God and Amara are to some degree bound to it. As it demands their co-existence or co-death.

God Power
While God is technically a deity in his religion. He isn't of the same race of deities as the pagan ones. His magic falls under a different type than the pagan gods. His magic is completely independent of tribute. Unlike how the pagans were greatly stronger than present time when given tributes. Amara God's sister has similar properties to her power. Enabling her's fog to awaken a Prophet of the Lord. God Power is immense as it can create worlds. Their power and being also functions as part of the Pillars of Reality in The Natural Order. It also services as if the universe lost the Light or the Darkness the lost of one of them and their power would undo reality. This could be prevent if the universe lost both of them.

Angel Magic
Angel magic is an extremely powerful form of magic that is strictly practiced by angels. Because there are many variations of angels, there are also many variations of angel magic that is specific to the angel. For example, while celestial angels are known to possess highly advanced and very powerful angel magic with the ability to banish demons, resurrect the dead, and travel through alternative dimensions, other angels are unable to achieve these feats of magic. However, angels can be limited on what they can do. This can be because of Heaven's Laws by whom is in command at the time, the factor of strength each angel's grace is, as well as other magic at play like Enochian Magic. Some other supernatural beings such as Eve and Leviathan can cut Angel's off from their power or prevent them from using their abilities.

Demon Magic
Demon magic is a very powerful form of magic that is strictly practiced by demons. Due to the fact there are many variations of demons, there are also many variations of demon magic that is specific onto the demon. For example, while most demons are known to possess the basic powers of super-strength and telekinesis, other demons have been shown other advanced powers such as mind control and teleportation.

(Note: Although demon magic is inferior to angel magic, it is superior to human magic. Contrary to popular belief demon magic is very lawless and can be used however a demon sees fit. However, some demons, such as crossroad demons, can create their own rules that they may dismiss at anytime. For example, most crossroad demons provide contracts to humans in exchange for their souls, promising them 10 years or more for whatever they wish. While most demons are loyal to their promises, some demons have been known to swindle people by killing them sooner than their deal.)

Fairy Magic
Fairy magic is a powerful form of magic that is exclusive to fairies. Because there are many variations of fairies, there are also many variations of fairy magic that is specific to the fairy. While bright fairies practice bright magic, dark fairies practice dark magic. Fairies also exhibit other powers such as shape-shifting, telekinesis and teleportation. Some fairies share similarities with genies, where they are forced to grant wishes to the person who has summoned them. Other fairies share similarities with demons, where they will make deals with humans in exchange for their souls or something of value to them.

Human Magic (Witchcraft)
Witchcraft is a practice of magic that encompasses many different types of activities including astrology, divination, spell casting, and spirit communication. It includes the practices of many cultures, nations and religions as well as many books and writings from ancient times. Depending upon the individual, some humans practice their power by certain belief systems, such as Voodoo, Wicca, or any number of other magical practices from countries and cultures all around the world. Magic used by extremely talented witches like Rowena is also able to heal even the most powerful beings like Amara.

(Note: Although witchcraft is commonly practiced among humans, other species have been known to practice witchcraft as well. For example, a crossroad demon gave Becky Rosen a love potion that she used to make Sam Winchester fall in love with her.)

Pagan Magic
Pagan magic is a very powerful form of magic that is strictly practiced by Pagan Deities. Human and other kinds of tributes and sacrifices seem to increase its potency. It seems the act of tributes is the factor, rather than worship of a deity or deities. Pagan deities have taken tributes from humans, that don't worship them; as well actions done by humans have attracted deities that aren't a follower of the respected deity's religion and taken them as tributes.
