Mana Skin

Mana Skin (マナスキン) is a basic Reinforcement Magic spell.

Description
The user creates a coating of mana that protects them. It is a basic technique that most Magic Knights have used unconsciously at one point or another. Proper training allows a mage to use it consciously and to greater effect.

Environments with strong and wild concentrations of mana, like Grand Magic Zones and dungeons, make it difficult to maintain the technique as the coating has to adjust constantly to the changing mana.

Elves' overflowing magic naturally forms a similar defensive barrier around them.

There is a special magic tool that applies a special marking to aid in the creation and maintenance of a mage's Mana Skin. This white flame marking relies on the bearer's magic, so if the mage loses control of their magic, the spell will dissipate.

Trivia

 * In the anime, Asta uses an Anti Magic coating to imitate Mana Skin during his second visit to the Ultime-Volcano Mountain Trail.
