Holy Magic

Holy Magic (神聖魔法) is, in essence, a type of Spirit Magic where the contracted spirit is divine in nature.

Principles
For a person to use Holy Magic, they need to form a 'pact' with a god or be a god themselves. Once a pact is created between the god and believer, the believer uses their god's "name" as a medium to open a soul-based channel between the two, offering magic power in exchange for the god's assistance. On the god's end, since there's no way to assist many people at once, they link together and borrow the cumulative calculation power of their believers to share the burden of putting the magic together. Since the burden placed on the user is low, the resulting holy magic's strength depends almost entirely on how much "Faith" the user has in their respective god. The stronger the believer's "Faith" is, the stronger the connection between the two is, and as a result, the stronger the magic becomes. This system as a whole is collectively referred to as the Secret of Faith and Grace (信仰と恩寵の秘奥).

Usage
Holy Magic can be split into two distinct categories based on the type of power being borrowed from/used by the respective god.

Basic Level
Basic level Holy Magic makes use of holy-type energy that can purify magicules and heal wounds. While its offensive options are minimal and don't work very well against regular beings, against monsters and especially undead they're almost always a sure-fire kill.




 * Recovery (傷病治癒): Healing Magic that closes wounds and reattaches severed limbs. Cannot restore the target's stamina or blood supply.
 * Healing (体力回復): Healing Magic that restores the targets stamina and lost blood.
 * Holy Cannon (霊子聖砲): A focused beam of holy energy fired outwards that rapidly purifies the magicules of a target on contact. The strongest single target attack spell in basic level holy magic.
 * Holy Bell (聖なる福音): A wave of holy energy surges outwards from the user in all directions, purifying a large amount of magicules and destroying monsters while the sound of a bell sings their requiem. This magic is traditionally used to purify Undead.
 * Prison Field (四方印封魔結界): Barrier Magic that keeps monsters from escaping while filling the area with holy energy. This greatly weakens most magical beings and even upper level Majin will find themselves in a much tougher fight because of it.
 * Holy Field (聖浄化結界): Barrier Magic that works under the same principle as Prison Field but ramped up the the max. Usually maintained by several high level practitioners working in tandem, within the radius of the barrier purification of all magicules commences. This outright kills any weaker monsters and those that manage to survive will find themselves greatly weakened and unable to use Elemental Magic and Magic derived skills.
 * Turn Undead (死者浄化：ターンアンデッド)

Miracle Level
Miracle Level Holy Magic or God's Miracle (神の奇跡) makes use of a god's power to manipulate Spiritrons. The magic belonging to this category is immensely powerful and the offensive spells it offers are lethal regardless of if the target is a monster or not. Even an Ultimate Skill user with their immunity to lesser forms of magic will find themselves in danger against the power of Miracles.


 * Regeneration (部位再生): Healing Magic that can completely heal almost any injury and restore missing limbs and organs.
 * High Heal (上位回復): Healing Magic that restores a persons stamina and restores lost blood but on a much greater level compared to "Healing". It can also be used over a wide area for the healing large amounts of people or large areas of plantlife.
 * Resurrection (死者蘇生): Healing Magic that completely heals the target and can even bring them back from death if their soul is still present.
 * Disintegration (霊子崩壊): In a process similar to nuclear decay, spiritrons bombard the target and destroy them all the way down to the soul level.
 * Overdrive (霊子暴走): A Disintegration spell but let out over a wide area similar to Holy Bell.
 * Holy Blade (聖剣発動): The user or targets sword is coated in a layer of volatile spiritrons capable of slicing through almost any barrier.
 * Holy Ray (霊子閃光波): A spell devised by Rimuru. The user fires rays of volatile spiritrons from their finger tips. The power is adjustable and its lack of holy energy makes it safe to use even for monsters.
 * Holy Ark (聖櫃): Sealing Magic that locks the target away in a coffin made of dense spiritrons. It's filled with so much holy energy that even a True Demon Lord will find themselves severely burned to the touch.

Trivia

 * Since holy magic is usually associated with the Western Holy Church and monster slaying, it is widely believed in-universe that monsters are not capable of using holy magic. Therefore, most characters react in shock when they see a monster casting it.
 * In Luminism being able to use "Miracles" is required to advance to the rank of Bishop.
