As discussed briefly before, most vampire weaknesses (at least for Western vampires) are associated with Christianity. Those that aren’t are largely fatal to, well, just about anything. Fire, for instance, is quite universal in its ability to destroy humans and vampires alike. The same holds true with decapitation. Stakes, interestingly enough, are not destructive to vampires (more on this later), but are quite deadly to human beings.
In addition to the supernatural weaknesses, there are also apotropaics, which cause no harm, but ward vampires away or limit them in some fashion. So the breakdown goes as follows
- Weaknesses (causes harm): sunlight, holy water, cross/crucifix, wooden stake
- Apotropaic (wards away): garlic, threshold, running water, mirrors
Each of these will receive a treatment, exploring the history and why behind them.
