Von Hasselhoff's Skin Condition

What's it called? Von Hasselhoff’s Skin Condition (in short, VHSC)

What does it do? This is one of the necromancer spells. When cast on someone, it causes them a horrible skin disease that lowers their stats and gives some damage over time.
The spell doesn't cause much damage, but it can be annoying, as its effects take some time to pass. If the component (a whole human skin) didn't weigh so much, it would probably get a great deal more use than at present, when it is seldom seen except as an expedient for taskmastering some healing while on the way to other spells (like Wungles's).

Where is it? Part of the set of spells that torment the flesh and employ dead corpses as component source, it belongs to the Body Parts for the Advanced Student grimoire, at the Unseen University Library.

What does it require? A human skin, which is consumed in the process.

What skills do I need? Convoking, Healing, Charming, Binding

Has it worked? The proper output should read something like this:

You prepare to cast Von Hasselhoff's Skin Condition on xxx (target)
You roll the skin up and tear several holes into it.
You take the rolled up skin and slowly twist it until it begins to break and bleed.
You utter random magical-sounding gibberish from deep within your throat.
You stroke the skin gently then point at xxx.
A wave of darkness washes over xxx and after it passes you see xxx’s skin seem to twist around her/his body, tearing painfully away from the flesh and fat underneath and leaving horrible wounds in its wake.

Von Hasselhoff's Skin Condition - Give the target a horrible skin condition.

Like so many inventions, Von Hasslehoff's spell was a failed result of another experiment. Attempting to cure acne actually resulted in this horrific skin disease that is painful and debilitating to the target. Von Hasselhoff died famous among necromancers, but still pimply.
