Wolfhowl is a unique Fury Visor. Used mostly as a novelty, Wolfhowl gives a Barbarian the ability to use Druid abilities, most notably Werewolf. While the form is rather pathetic compared to the Werewolf Druid, it does allow Barbarians access to Feral Rage, which lets them add to their life steal. The Life % is always welcome, especially if the Barbarian uses Battle Orders before transformation.
