Make a Martial Arts check against the vampire's Creature Power skill. If it fails, make a mutation check for yourself, adding the amount of difference between success and failure to the difficulty. Instead, an area with the opponent as its center is plunged into sunlight until the end of the sequence. The area has a radius in meters equal to your Outcome. Unless the vamp is somehow immune to sunshine, after the first shot, give them appropriate damage.

Repetition makes everything funnier. Yeah, it's true. Repetition makes everything funnier. Unless it makes it annoying. Yeah, that, too.
