Beast Summoning Magic

Beast Summoning Magic (野獣召しの魔法, Yajūmeshi no Mahō) allows the user to bring forth objects from another dimension, or point in space, and have them appear in the space where they place a magic circle. However, this particular type of magic require the user to make a contract with a creature with whom they can use in combat. 
== Description ==
In order to make a contract with a beast and have them be summoned into the caster's dimension, a caster must create a rune seal unique to said beast while placing a drop of blood from both the user and the beast. By concentrating Ki into the fingertip, the caster can create a unique runic string that can be "tattooed" or "stamped" onto the body of the beast. This summoning seal connects the user's Ki with that of the beasts; allowing the beast to appear when their particular rune scripture is drawn by the caster on the battlefield and the proper incantation is said. This seal also allows the user and the beast to communicate with one another through the process of sending the user's ki in unique pulses to that of the creature's brain, allowing them to process speech, even if the species themselves is unable to reciprocate.
The beast themselves to not rely on the caster's Ki, and are free to use their own magical power during a fight. However, in order to be summoned, the caster must use the magical energy equal to at least 60% of the creatures magical energy. This means that the more powerful the beast that is being summoned, the more magical energy must be used by the caster to get the beast to their own point in space. This rule is easy to overcome when the beast being summoned is not of the magical nature, and relies on brute force or innate abilities like flying, but when calling upon a creature with whom holds a great deal of spells at their disposal, a mage will have to have an exceptional amount of skill to bring forth the creature to the battlefield. It is possible to summon more than one creature to the battlefield as long as the combined power of the two beasts do not exceed that of the caster, if so, the caster will be drained of energy immediately. 
Due to their nature as living, breathing creatures, when taking damage in battle these beasts will sustain injury just as that of a human would. The beast is capable of reversing the summon if they are of the magical nature and have enough of their own Ki to perform a reverse summon. A reverse summon is simply done through a standard runic strain that must be written with the same Ki that performed the initial summon.
