Magoi Manipulation (魔力（マゴイ）操作, Magoi Sōsa) is the ability to manipulate the energy created from Rukh, Magoi, within one's body. Magicians also have this ability, but unlike non-magicians, they were basically born with this talent; they didn't have to learn it making them unfit to teach it. The Yambala Gladiators is a race of people who specialize in this ability and its various methods. There are various ways to do it, such as:
- One such way is the ability to use the Magoi within one's body to counteract an opponent's Magoi, thus negating their ability using the hands.
- Another way is the ability to entrust one's Ki (Magoi) into a weapon (whether it be a sword, spear, shield, etc.,), thus making it strong enough to pierce something even normal physical attacks can't damage.
- Another method is where the user learns how to combine his Magoi Manipulation with their Djinn's powers, to easily learn Djinn Equip.
- It can also be used as a form of medical diagnostic test as it allows the user to look inside someone by touching their veins and feeling the flow inside their body.
If any of these methods are used on an opponent and connects or graze that person, it can cause internal damage to that person.
