The basic build is like this...
Lycanthropy 20
Werewolf 20
Fury 20
Oak Sage/Heart Of Wolverine 20
The you can get Carrion Vine and Grizzly if you feel like it. I recommend Oak Sage, because of it's huge boost to life. Strength is just enough to equip your gear, dexterity is best left at base, and then the rest into vitality. Werewolves are mostly better off using 2-handers...They have good life and can take a beating, and the extra damage is sweet. Wolves also have very slow blocking
It's very important that you choose a very fast weapon, because Increased Attack Speed from gear like armor/gloves doesn't help. An upgraded Ribcracker with a Shael rune would be an awesome weapon. IK maul isn't bad either, and of course there's stuff like Breath Of The Dying which is also nice.
