Blood Seal Magic

Blood Seal Magic is a rare type of Magic that lets the user tame demons, absorb them, and summon them by drawing a symbol in blood on their body. Because of the dangerous nature of this magic, people often don’t see the risk is worth the power it grants.

The Ritual
Blood Seal Magic has a rather unique method to attaining it, involving several steps. The first is to hunt down a particularly powerful monster and fight it to within an inch of its life. Then a ritual is performed, and the essence and mind of the beast is sealed within the body.

The host then has to battle for dominance against the new host, during which the If host’s body will go on an animalistic rampage, destroying everything in sight. If this lasts for more than an hour, then the host is considered lost and the body will belong to the monster. If this happens, then the monster will rampage until its new body literally falls apart from the strain, or it is killed by another mage.

The Seal
If the host is successful, the monster they absorbed immediately gains all the knowledge the host has, and is able to speak with their host. To access the powers of the magic, the host must draw a symbol in their own blood on their body, where in the beast they absorbed will seemingly erupt out of its host in the form of a weapon. The location of the seal is completely random, but is generally located on the torso or upper arms. This new weapon grants the user great destructive power, but still has to fight for control against the will of there weapon.

The Demon Weapon
The weapons summoned by these means are referred to as Demon Weapons, because of their look. These weapons are very much alive and almost always fight for control of the host’s body.

When in use, the Demon Weapons each poses an ability that can be used in combat, depending on what the monster was originally. This could range from something like doubling the user’s strength or letting them read an enemy’s mind, to simple tricks with the weapon like having the blade segment into a whip, or vibrating like a saw.

When summoned, the Demon weapons appear to still be made out of flesh and bone, instead of metal, but they are always adorned with an eye some were on it. These weapons are very durable and don’t require any form of maintenance. While in use, one of the eyes of the host takes on the same color as the weapons eye, with also glows in low light. This limits the user to only using two weapons at one time.

While durable, if they are ever broken, the monster effectively dies, with the eye going dull in color and the presence fades from the host. The weapon may still be usable, depending on the damage, but any extra power granted by it will be inaccessible. If called on, instead of glowing, the eye that is possessed by the weapon will simply go blind, returning to normal when the weapon is re sealed.
