Can werewolves hurt other werewolves/monsters that are immune to normal attacks?
Werewolves and other special creatures like them do not innately possess any special ability to inflict damage on other special creatures. This is the official word from WEG in Infiniverse #11. However, it is possible that the creature may be aware of the other creature’s weaknesses (such as being hurt by silver) and can use that to hurt the other creature (the infamous ‘silver claws’ of the weretiger that Kurst fought in the third Torg novel). There is also a special power that Orrorshan Horrors may possess that will allow them to hurt other Horrors that are resistant to normal forms of attack.
