Holy Magic

Holy Magic (神聖魔法): Holy magic is, in essence, magic involving manipulation of spiritrons. It can be used for healing, resurrection, or means for direct attack.

Principles
As spiritrons are particles that could transcend space-time, controlling them requires immense computing power and thus cannot be achieved via normal means. The most efficient way to achieve this, is to establish a pact with a higher entity and borrow its computing power to cast the spells. The user doesn't need to gather up magicules from the atmosphere, and it wasn’t affected by the magic strength within the user. If the user has the right knowledge and enough time for chanting, they could weave powerful magic without exerting a great deal of energy.

What it does require, though, is a pact forged with a "god". A god, for the purposes of this kind of magic, is an existence powerful enough wield the spiritrons. It isn’t dependent on the caster believing in this or that god, or some other divine concept.

In Luminous Faith, Luminous Valentine is a god for this reason. Even Hinata cast holy magic by borrowing Luminous' powers. It could work as long as the god consented in lending his/her power in some way, and the god himself/herself doesn't have to be able to use holy magic. Dragon Faithful are able to use holy magic due to their belief in Milim Nava, despite her not being able to use it at all.

As long as the individual is powerful enough understands the mechanism, s/he can even cast holy magic without having a god as a medium, as proven by Luminous and Rimuru. Moreover, less powerful individuals who has access to sufficient computing power through their skills can also cast holy magic on their own to a certain degree, like Shuna who did it through her Unique Skill "Analyst" (though it is more efficient to borrow Rimuru's power).

Usage
There are two types of holy magic — the one with holy attribute commonly used for healing and purifying magicules (most effective against undeads and demons), and the neutral type which directly weaponizes spiritrons. Examples include:


 * Heal (holy)
 * Resurrection (holy)
 * Holy Cannon (holy)
 * Holy Ray (neutral)
 * Disintegration (neutral)
 * Melt Slash (neutral)
