How do you even kill a succubus????

Succubi are imaginary. They don't need killing, since they don't exist.

I think it involves fresh chicken blood, and cigar smoke, and certain incantations, but I'm not an expert.

The chicken blood does not have to be fresh; it just can't be dried. Having said that, I would add that the things that you've mentioned have been shown to have only a sixty-five percent success rate. Anyone who tells you different probably makes their living selling fresh chicken blood, cigars, and secret incantations.

If you really want to kill a succubus, contract AIDS (how you do this is your business), and soon enough the succubus will die.

Well theres sightings but yeah they are imaginary, I belive theres some type of demonic succubi things.

But what if I get my chicken blood in organic artisanal powder form from Dean & DeLuca? Would that work?

I don't see why it wouldn't. But is it really worth the risk of being succed? You can't go wrong with the old tried and true method involving chicken blood and cigar smoke.

Ya know, when I think about it, why would we want to avoid an encounter with an experienced succubus anyway? Maybe it's just an old wives tale that something bad will happen to you if you take advantage of the offerings from one. And maybe the old wives' motivation for telling the tale is to keep their husbands from really having a good time. After all, chicken blood and cigar smoke would certainly be a turnoff; it would turn me off.
