Warlords of Draenor - Garrisons: Barn

Barn

The Barn takes up a Medium plot which can also be used for a Lumber Mill, Gladiator's Sanctum, Trading Post or Inn / Tavern. Once upgraded to Tier 3, your garrison will have two Medium plots available.

Abilities
This building is good for stockpiling leather, meat, fur, and Savage Blood for crafting epic armor and weapons.

Level 1 - Allows you to capture clefthoof, elekk, wolves, and talbuk for leather and fur. Used for leatherworking and tailoring recipes.
Level 2 - Allows you to capture boars and riverbeasts for rare meats used to create the most powerful food.
Level 3 - Allows you to capture elite beasts to harvest for savage blood, used in all epic crafted armor and weapons.

Level 3 Unlock
The Level 3 version of this building is unlocked by completing the Master Trapper achievement. Unlocking Level 3 will give you access to the Pygmy Cow. The Glass of Warm Milk can spawn on the first or second floor of the barn.

Work Orders
The Barn allows you to capture animals in traps, which gives you caged animals. You can then trade 1 of these animals for leather, fur, food, and the chance for Savage Blood.

For an added bonus, you can get a follower with the Skinning ability to work in the Barn. Currently Goldmane the Skinner is the only follower with the ability accessible to everyone. You can find him in Nagrand by killing Bolkar the Cruel. You can use Goldmane's Cage Key from Bolkar to release him and claim him as your follower.

Dark Ranger Velonara / Hulda Shadowblade is the other follower with the Skinning ability, unlocked by completing the Standing United quest in Spires of Arak.
