This battle pet is a quest reward from the hidden quest, [60] Tale of the Phoenix.

To unlock the quest and obtain the pet, the player will need to obtain the following items:

Follow these steps to obtain the items:

Loot 10x [Sacred Phoenix Ash] from Small Pile of Ash, found in Cooking pots in the Spires of Arak. There are ten known locations (with the map being available on the Small Pile of Ash page).
Loot 20x [Inert Phoenix Ash], which drops from the Scorching Elementals and Living Blazes in the Fire Plume Ridge of Un'Goro Crater.
Obtain the [Glittering Phoenix Ember] from Alysrazor in the Timewalking difficulty of Firelands. This will require the Cataclysm Timewalking event to be active. The entire raid will be given the item upon defeat.
After obtaining the three items, go to Zektar in Spires of Arak^{[52.09, 50.48]} and trade them for the [Phoenix Ash Talisman].
Loot 20x [Ash Feather]. To see these feathers, purchase the [Ash Feather Amulet] from Griftah at the Obsidian Throne in the Waking Shores. Using the amulet will let you periodically see the Ash Feather on the ground that can be looted.
Loot 15x [Smoldering Phoenix Ash] which can be looted from Phoenix mobs throughout the Dragon Isles or Dragonflight dungeons such as Neltharus.
After obtaining the required items needed, go to Tarjin the Blind in the Waking Shores^{[16.16, 62.62]} and he will now offer the quest that rewards the pet.
