Vodou

Vodou (ブードゥー Buudouu) is an ancient form of magic that blurs the line between magic and religion, it's practitioners sharing a strong bond with the spiritual realm and the powerful creatures that reside within. To be able and actively use this magic, the mage must form a connection with one of the spirits of the wild, also known as Loa, and they, in turn, must bestow the mage with an idol, an item through which they will channel the powers of the Loa. Should the idol be lost, the mage will be left powerless. To practice this magic is to embrace chaos, to understand that nothing is within one's own control and that everything you do is by the Loa's good graces. All spellwork is of their origin and will only remain by your side for as long as you give more than you receive, as long as you remain a faithful and devoted subject.

Description
As mentioned previously, Vodou is an ancient form of magic as well as a holder type magic which is both a magic and a religion. Vodou is a very fickle magic as the ones responsible for the spellwork isn't even truly the mages, but rather the spirits which they revere, which in turn can sometimes be rather chaotic in their behavior, preferring to never feel bound down to a single user. If two mages who both practice the same magic, the spirits will not treat them as equals if one is of greater standing amongst the Loa's than the other, making it more than possible for the spirits to abandon the lesser standing mage in favor of the other. Granted, there are many kind-hearted and loyal spirits, but more often than not, the Lesser Loas, as well as the mightiest of them, are the most fickle ones, mostly due to either a ferocious nature or due to the arrogance they carry from the immense power they wield.

To practice the magic and form spells with the loa's, the mage requires and idol. This item, whichever form it may take, is an item which has been gifted to them by the very Loa which they worship. This idol is the very means which through they cast their spells and without it, they will be worthless. In order to receive and idol, the mage has to begin by devoting themselves to a Loa. It doesn't matter which one, but they have to pick one and go through rigorous trials in order to come in to their good graces. Once the Loa has witnessed and acknowledged the efforts of the mage, the god will grant the mage the option to accept them as their patron Loa. If they accept, the Loa will bestow upon them with an idol to help them in combat. While a mage can procure more than one idol, they can only have one Loa as their patron, and the idol from said patron will always grant the mage their most potent spellwork and even grant them their most potent ability, something which will be detailed further below. However, just because an Idol has been acquired, does not mean that their work is over. If the mage does not continue to show their devotion and show respect to the Loa(s) which has bestowed their idols upon them can and will result in the Loa's taking their Idol's back, leaving the mages with nothing.

Each Loa's can bestow their mages with unique abilities and/or properties in return for their devotion and sacrifices. While the more basic spells require little else than a mage's own magic power in order to function, the higher states of spellwork will require the mage to perform a worthy sacrifice of sorts in order to receive the Loa's boon to perform such a spell.
