Celestial Spirit Magic is a Holder Magic used by Celestial Spirit Mages.
It is a Magic in which the user summons Celestial Spirits by opening their gates through the use of Keys. These Keys are separated into two classes: the more common Silver Keys and the rarer Gold Keys.
You start with these two spells: Summon Celestial Spirit and Force Gate Closure.
And you can start out with one key; either gold or silver. But be sure to be able to rp out/explain how you got the key. Silver keys are likely to be sold in shops while gold keys have to be given by another Stellar Spirit Mage or by the Stellar Spirit themselves.
Celestial Spirits drain you MP each post you have one summoned(can only have one summoned at a time). They drain your MP by: 50 to summon and 20 to keep summoned (each post). If your magic hits 0, you pass out.
Also, when you start out as Celestial Spirit Mage you are allowed to have one Key to start with(you don't have to though). But, please try not to pick the strongest Keys to start out with, like Leo, Capricorn, Aquarius, ect.
