Mana Zone

Mana Zone (マナゾーン) is a advanced Reinforcement Magic spell that surpasses Mana Skin.

Description
The user exerts control over the ambient mana within an area. Offensively, this increases the amount of mana that can be used in an attack, as well as the number of attacks. It can also be used to attack from all-around, within, or behind a target.

Defensively, the mana can be used to predict enemies' attacks and to move in mid-air.
