Something i would like to add, since i did not found any mention in the lesser black magic themed topics and is imo something to not underestimate, is the use of fragrances.
I personally prefer oils over perfumes or colognes since, next to the fact that they're more natural, they are also more subtle.
Also you can make your own blends and magical recipes for oils.
Also, the use of semen, extracted during particulair moonphases under the specific ritual workings, with focus on a certain intent, have been of great value in some mixtures for some more specific works of vampiric enchantment.
