Mystica/Physical

Physical Type Magic is one of the uses of Mystica manipulation. This is considered to be one of a melee fighter’s greatest assets. 
Physical type magic is one of the major forms of magic that are taught to trainees of magic. Users must be very talented in order to perform this magic, additionally, they almost always must be naturally gifted in terms of physical strength and raw power. This is because physical type magic is a double edged sword, on the negative side of the sword, this technique harms the user and can even tear and fatally damage their muscles within the body. Meanwhile, on the positive end of the sword, the user has the powerful ability to manipulate their level of strength. Of course it is limited, from a minimum of 2x to a maximum of 10x the user’s original power. Users can even amplify their muscles even further to increase their durability as well as their strength. 
By increasing and amplifying the user's level of fat and muscle within a certain part of their body, they are able to increase their durability by multiple layers of ten fold. This is a technique used to help the user survive specific attacks aimed at them, they mainly use this technique on the parts of the body that are most fatal if ever to be damaged severely. In addition to the layers of thick armour protecting that specific point, users can also channel Mystica energy into that part of the body to grant the user even more durability. Those who use these forms of magic are trained in terms of endurance and stamina due to the fact it’s a very draining way to manipulate Mystica, in addition to the internal and external physical damages that this form of magic applies to the user no matter how weak they make the technique.
