Orgone is the measure of a person's connection with the cosmos. It is the conduit through which the power of the cosmos flows, focused through a sorcerer's will. Ritual practicioners must draw on this reserve of power to make a magic spell work. Spells require a constant infusion of Orgone through rituals that are performed inside a transmutation circle. These rituals require a number of ingredients and can last anywhere from 30 minutes to several hours depending on the spell. There are five types of magic that spells revolve around.
Enchantment Spells – These are spells designed to capture cosmic power within a crafted item, so that its power can be called upon in times of need.
Scrying Spells – These are spells designed to allow a user to perceive in ways that go beyond his fve senses.
Protection Spells – These are spells designed to ward a user, object, or location against a variety of possible harms
Transmogrifcation Spells – These are spells designed to fundamentally alter or control another being
Transmutation Spells – Changing the makeup of different materials or combining them with others to make new forms of matter.
A mage can create a familiar, creatures made purely from orgone, to assist in their rituals. They are made from a mage's souls and serve as a direct reflection of their inner self. They may have unique abilities, but their main purpose is to serve as magical batteries. They allow a mage the ability to bypass ritual circles and their ingredients to perform spells, reducing time frame from hours to literally minutes. They also make the particular spell more powerful, allowing mages to become masters of their craft. The drawback is that it limits a mage to one of the five types of spells. While these specialist mages are the most powerful individuals in their field, once they choose which form of magic to master, they lose the ability to perform the other types forever.
I need a good reason for why a familiar binds their mage to a particular type of magic. Why would it make you all powerful in one but block your access to others?
