By drinking this, you gain the ability to turn into a ghost!
*As a ghost, you are, of course, intangible and thus impervious to physical attacks. This doesn't protect you from anything spiritual or magical.
*In a process somewhat similar to mitosis, you can split yourself into any number of clones, each retaining the abilities of this essence and this essence only.
*These clones retain all your knowledge, skill, and personality up to the point of the split. That said, after the split, these attributes could grow very different from you.
*As is typical, you can possess most living things and any inanimate object. Beings which possess high amounts of willpower will be able to resist and throw off your control at times, however.
*You have the ability to change your host's shape, giving them any features your ghostly form possesses, and enhancing those they already have.
*You can access your host's memories and personality so as to better sell any deception to their family and friends. This won't influence your own personality unless you decide otherwise.
*You can cause objects to levitate in the air and even telekinetically throw them at people. This does have some limits though. For instance, your range is limited to whatever room you're in. Another is speed; You can't toss them much harder than you would throw a baseball.
*You gain the ability to manipulate ectoplasm, one use being to change the shape and gender of your ghost form or that of any other ghosts you encounter.
