Are Vampires affected by tattoos in the shape of religious symbols?

This does extend to tattoos, with some limitations and quirks.

A vampire will be repelled/burned by a tattoo in the shape of a religious symbol (regardless of religion) on their victim only if they come into direct contact with the tattoo. That is, the skin of the vampire must come into direct contact with the skin of the victim upon which the tattoo is inked. Sight of the tattoo alone is not enough.

The exception to this rule is for 'enhanced tattoos'. If, when it is inked, the tattoo is enhanced by the religion from which the symbol comes, then the vampire will be repelled by the tattoo on sight and skin to skin contact will not be necessary (though contact will still be required for burning). So, for example, an enhanced tattoo of a cross could be created by using ink blessed by a priest (Christianity) or created via a Voodoo ritual (Voodoo).
