[General] Vampires and religious symbols

I'm worried about defending myself against vampires and need to know if only crosses work, or should I also carry around other symbols, like a star of david, or a star and crescent.

Different rules for different universes. The possibilities run the spectrum from:

* Only crosses
* Only blessed holy symbols
* Any holy symbols
* Only holy symbols that the vampire believes in
* Some other unique-in-universe symbol
* Any of the above but with varying effects (ie. some hold vampires at bay, others can burn them)
* Symbols don't do anything at all (usually when vampirism is classified as a virus or parasite.)

So first, you need to provide some information about which of the above universes you are calling from.
