Blood Rune

A blood rune, also known as a blood seal, is an alchemic technique to bind someones soul to inanimate object.

How to
User of technique must draw a rune with his own blood to inanimate object (usually armour) and then somehow call the wanted soul into it, filling the object with the soul.

Plus
A person, whose soul is bound to an inanimate object feels no pain, hunger or fatigue thus enabling them to perform immense physical feats. Also, as the person has no body, he or she can sustain more damage than normal humans.

Minus
One, whose soul is binded with blood rune is almost invulnerable. He or she has only one weak point, the rune itself. If rune is in some way damaged, the persons soul will start to fade from the object. This makes the protection of blood rune the most important task of the binded. Sometimes, person inside the object will start to question his or her own existence. This can be very dangerous to persons mental health. Yet, there is a bigger danger. If ones soul is binded to inanimate object for long, the soul and object will start to repel eachother. Person will start to experience moments of sleepiness, which causes persons soul to disappear from the object. This can lead to complete destruction of the soul as it slips away to The Gate. This makes the blood rune only a momentarily effective technique.
