This piece summons a Burmese vampire from the tribes of Karen. No, this is not like the Karens that ask for the manager. The Karen tribes are actually a sect of Burmese people that thrive on different types of magic, but mostly the archaic type that comes from ancient times. This is what the Kephu Vampire offers you when you wear this piece. You will need to place a small drop of blood on this piece and wear it from a period of 7-14 days. During that time period, the vampire will appear to you in spiritual form or in a telepathic form. You will be able to ask him for sources of ancient magic to manifest in reality and he will give them to you. Not only will he do this, but he will also allow you to "see" through his "eyes" by acquiring his knowledge. This will show you the journey that he has been on and how he has acquired each magic that he has mastered. He does not have a name, you will simply refer to him as Kephu.
The piece you are getting is a costume ring with a black stone.
