Transcendancy

 
  The process of transcendancy is to focus on a bloodstone in a cup and drink a drink to shift to the chosen target, to do this correctly fill the cup with blood, or other drink. Then as you drink, think on the ruby and mentally join the target to be. This is done to save your life as it kills the body you are normally in or leaves it knowledgeless. You knock out the body conscious of the victim to become the victim. This can be done when your near death or very old in physical form. Then you make it up as to your identity change and hope your whomever your with, albeit spouse, or girlfriend accepts you. Another possibility, is the body won't die off and will form a new personality to remain alive.
