Vampires also have improved senses and all a werewolf form is useful for is Killing and they don't get all the abilities a vampire gets they are not immune to poison infact if anything they are weaker due to a sped up metabolism and since when did Vampires eat anything? and whats this about the human brain here, vampires ain't human once they turn into vampires... they are vampires and I am sure werewolves get many many diseases when eating the raw flesh of some random creature.
What is the basis for a vampire brain? Oh right a person...
"They aren't human anymore!" Well they still were human and operate on the same wavelength.
Also depends on how recent they turned but still they obviously eat. I mean look at the bloody bones and eviscerated cattle in Castle Volikar.. That is more than just drinking blood. Justification is probably just trying to keep a semblance of humanity.
Depends on the universe but also the faster metabolism plus a stronger body means more poison immunity as well. Also I like the "I am sure werewolves" That makes no sense because this is a hypothetical.
But if we use the skyrim universe they are immune to disease. So... It usually works out.
I guess I have to ask this. Why do vampires have more weaknesses?
Stakes, sunlight (Common), garlic (Comes from the fact garlic has something in it that helps fight disease, and vampires have a plague victim association), Silver (Just a general supernatural combat thing and some sacred standing), Beheading, Religious symbols of whatever religion they think will harm them (From the concept that a jewish vampire wouldn't be affected by a cross but still hurt by a star of david), Seeds on the ground (The myth is vampires would be compelled to count them all and then usually get sun'ed out), Cant cross running water (forget where this one comes from), etc.
Werewolves: Silver (actually just depends, sometimes it means nothing), and... Yeah you could say normal death markers... But... they are super fast, heal, and depending on the universe they can change as will.
Also... Werewolves don't sparkle. In any media.
