The Dark Wolf is the Evil cousin of the Dire Wolf. Like the Dire Wolf, the Dark Wolf likes to attack Good or innocent creatures. Oddly enough the Dire Wolf highlights red and the Dark Wolf highlights grey. The Dark Wolf is about as strong and tough as a Dire Wolf.
The Dark Wolf is also a familiar summon for Necromancers. Necromancers of skill (60 Necromancy/60 Spirit Speak) can summon these fierce wolves to do their bidding.The Dark Wolf Familiar will attack the foes that its master attacks, and as an extra bonus it will allow its master to tame any wolf he meets in his travels.
