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 are a group 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.
- 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. Because the person is using one's very life itself, excess usage of Magoi, or if their bodies lack the ability to hold the Magoi, can lead to a number of problems, even if you are a Magi. Some problems seen are:
- Exhaustion
- Bleeding from the eyes and mouth
- Coma
- Shortens one's lifespan
- Death
