Blood Deity

Blood Deity was an Immortal Gu of the Blood Path Realm.

Ability
Blood Deity is used to turn a blood relative into a "Blood Deity". As long as the relative has your blood flowing through its veins then its considered that the said person is a blood relative.

A "Blood Deity" is the same as another life form. Once the transformation goes right all of the effects of the previous Gu used on the relative lose would become null. The sacrifice's thoughts are influenced by the "Blood Deity".

Transformation
To use Blood Deity the Gu Master would need to kill a living blood relative to obtain the "Blood Deity".

If the relative has agreed to give up its life, then the resulted "Blood Deity" would be closely connected to the Gu Master, thus being easily controlled. But if the relative bore both hatred and anger the "Blood Deity" will produce negative results for the owner.

To make sure nothing goes wrong the relative has to be convinced to become a sacrifice and there can't be any fury in the relative.

Conquest
The resulted Blood Deity has the same strength as a Gu Immortal. Having another one means a fight of two versus one and will it shall become a group fighting a single enemy.
