What versions of Werewolves and Vampires?
Are we doing the werewolf where once a month they are ravenous beasts who murder and commit mayhem. Or the ones who are unnaturally strong the entire month, but during their full moon, they can shapeshift and are even stronger. [gets stronger as the days get closer to full moon]
AND are we doing the classic Fright Night style vampire. Can't come inside houses, stakes, crosses [If only the user's faith is stronger than the vampire], beheading, etc. Or the ones from the Night Watch series that more or less follow the same rules but can go outside during daylight. Sunshine weakens them, but doesn't kill them. (To an 'Higher Vampire' he said the sun was an annoyance)
If it was classic vs classic, probably werewolf, just had to chain myself up near full moon.
If it was more 'modern' then vampire obviously. Blood Banks do exist for a reason, so if i need blood theennn... yeah
