Fang of the Wolf

The Fang of the Wolf is provided as an objective for Perfecting Your Howl.

You may use this item on foes defeated in the Regrowth or in Sethria's Roost. You need not target the foe, it will automatically select a valid target nearby. Valid targets are ones you (your group) pulled. (Noteworthy because you can get credit for defeating foes for The Protectors of Hyjal if you tagged them, even if you did not pull them.)

Using it increments the howl count for all members in your group on the quest.
