Amani War Bear

Source
The Amani War Bear is a very rare mount. The bear is decorated with tribal arms and decorations and was lootable from the reward chest after successfully doing the timed events in Zul'Aman.

Following the implementation of Patch 3.0.2, the Amani War Bear was removed as the reward and is no longer obtainable by players.

Announcement from Tigole, a Blizzard representative:

The Amani War Bear appears as a in Heroes of the Storm, where it was added in the same patch as Zul'jin. Despite the name, the Heroes Amani War Bear's coloration bears more resemblance to the Amani Battle Bear. The mount comes in two alternate colors in the form of "Crimson War Bear" (which bears more resemblance to the WoW version of the mount) and "Drakkari War Bear".

In Hearthstone
