Oh I don’t remember this, it’s been years since I played this game 
From what I remember both the vampires and the werewolves were kinda underwhelming though.
As a werewolf I didn’t even use his beast form at all (using your normal armor and weapons is much stronger) but just got it for the disease resistance. Being a vampire was also more of a disadvantage than an actual benefit so I never became one until I downloaded vampirism mods which made it a lot better.
