Devil Physiology (Black Clover)

==Summary==
Devils are an ancient race of magical and malevolent beings that dwell in the Underworld, a bleak world where the only amusement comes from tormenting each other and toying with the humans of the living world.
Normally, devils cannot appear in the living world on their own. A mage in the living world can use Forbidden Magic and a sacrifice to summon a devil and use some of its power. Devils cannot wield or enter a grimoire until it has a five-leaf clover. Once they have a grimoire and a physical body, they can unleash their true forms and power in the living world.
Because devils come from the Underworld, their mana is known to be malicious and sinister in nature, thus their magic attributes are particularly formidable and frightening. The only ways to counter devils' magic are with negative mana, Arcane Stage magic, Saint Stage magic, and other devils' magic.
Lastly, a devil's heart is its most vital body part; as long as the heart remains intact, the devil could eventually recover, even if the rest of its body is destroyed.

==Weaknesses==
*Arcane Stage and Saint Stage mages can destroy a devil's heart and kill a devil. For cross-verse matchups, this would involve the following:
**Arcane Stage: Arcane Stage encompasses mages who have deeply tapped into Forbidden Magic, and mages with the ability to interfere with the otherworldBlack Clover Volume 23, Chapter 228: Arcane Stage Mages. For the former, characters that are able to borrow the power of what would qualify as a devil in their respective verse (Unholy Manipulation) should be able to destroy the heart of a devil. As for the latter, not much is known as of now.
**Saint Stage: Saint Stage is a stage only Spirit Magic users can achieve. They can destroy the heart of a devil by cleaning/purifying evilBlack Clover Volume 30, Chapter 295: Rematch. As such, characters with the ability Holy Manipulation that works by purifying evil entities or Purification should be able to bypass the invulnerability of a devil's heart.
*A low-ranking devil lacks the invulnerability that devils of mid-rank or higher have, and can thus be defeated by their opponent attacking with power greater than themselvesBlack Clover Volume 29, Chapter 284: Ultimate Magic.
