Vita Vescentium ritual oil

This is as nefarious as it sounds. Vita vescentium works on a target's essence.

The focus from this one is quite a bit nefarious, it seeks to draw the life essence from the afflicted and elevate the one casting it. Your essence feeds upon the life essence of the target until the targets demise. Binding, submission,  consumption, corruption, submission,  and feeding off the lifeforce essence of the target. 

 This is without a doubt one of the darker workings of the crooked path.

Use on poppets, effigies, pictures, candles, writs, petitions, direct on the target if acceptable, and any other way you deem appropriate
