Warsong Direfang

Has a will of iron but is a sweetheart if you give it a clefthoof bone to chew on.

Riding Requirements:

This mount is available to all eligible characters on your account.
Level 10
Apprentice Riding

Source:

Dropped by Vengeance in Tanaan Jungle.
Dropped by Deathtalon in Tanaan Jungle.
Dropped by Terrorfist in Tanaan Jungle.
Dropped by Doomroller in Tanaan Jungle.

Notes:

One of three mounts that drop from elites found in Tanaan Jungle. The mount isn't directly looted from the NPC. Instead, there is a low (~15%) chance of each elite dropping a Rattling Iron Cage. The cage is guaranteed to contain one of the three mounts, though it's possible to receive the same mount twice. Each elite yields personal loot once per day.
