unnecessarily pedantic
So sunlight is supposed to kill vampires, right? Makes them burst into flames or turn to ash or whatever.
Is it specifically sunlight as in *light from The Sun*, or is it any light at a specific intensity? Is it only a single wavelength of light that's the issue, or a particular spectrum? Is there a threshold, or is it cumulative exposure? Can they go outside on a really dark and overcast day, or is that still too much sunlight?
