i got the chew toy title after 25 or 26 werewolf defeats. tho when i went back to the forest i still got attacked (tho it was on the same night. i'll try it again on the next night and see if i still get attacked)
edit1: i found the secret area in emerald road east. nice. liked it
edit2: i'm still getting attacked by werewolves. guess the perk doesnt do anything other than stop me from losing willpower after i get violated by the werewolves.
