Can only be used by Beast Mastery hunters that have reached level 10.
Location & Notes:

Located in The Necrotic Wake (Dungeon). Bonefang is the mount of Amarth and serves as the second boss in The Necrotic Wake. Taming Bonefang will prevent you continuing with the dungeon and it probably shouldn't be tameable at all. Consider taming a Flayedwing Fleshripper instead.
