Above: The barracks building in your Warcraft garrison offers you perks including a bodyguard that will protect you while doing quests. It can be built on a large plot.
Warcraft garrison buildings: a brief summary
This information is from the current beta-server build. Those buildings that have two names are identified differently for Horde and Alliance players. Horde names are listed first.*
Large buildings (five available, you may build two)
Barracks: At level 1, this unlocks patrol missions for your followers, which give better-than-average rewards. At level 2, you to take a follower out into the outdoor game world to act as your bodyguard. (You can do favors for Followers you use in this way, eventually prompting them to offer you perks, such as immediate access to a mailbox.) At level 3, you to have more followers at once, and gives you access to racial guards and banners in your garrison.
Spirit Lodge/Mage Tower: At level 1, this allows you to collect the bajillion ogre mage stones (Stockton estimates it’s 1,500 but isn’t sure) it takes to earn one portal you can use to transport your character to another place in the game world. At level 2, you can open a second portal; at level 3, a third.
Goblin Workshop/Gnomish Gearworks: At level 1, it creates an invention a day. At level 2, it adds five new (better) plans from which the item is selected. At level 3, it creates a siege vehicle once a day that you can use in the game world.
Stables: At level 1, it enables the capture and training of special mounts. At level 2, it allows you to remain on your mount when you click on items in the game world. At level 3, it increases your riding speed while mounted by 20 percent.
War Mill/Dwarven Bunker: At level 1, it increases the chance you’ll get a rare or epic-quality random Bonus Upgrade to a quest reward — a new feature in Warlords of Draenor — by 20 percent. It also enables you to collect armor scraps, which can be used to transform (transmogrify) the armor your character is wearing. Level 2 opens up the ability to make follower weapons and armor, and to unlock more visual transformations for your own armor. Level 3 gives you a bonus roll for gear in large-group raid dungeons at no cost once a week.
Above: The Warcraft Gladiator’s Sanctum is a medium-sized garrison building that offers bonuses that might be appealing to those who enjoy player-versus-player combat.
Medium buildings (five available, and you may build two)
Frostwall Tavern/Lunarfall Inn: At level 1, it offers a daily quest in a dungeon with “generous rewards.” At level 2, it grants you random followers each week. At level 3, it unlocks treasure hunter missions for your followers, which award high amounts of gold.
Gladiator’s Sanctum: At level 1, it increases the speed by which you recover from combat outdoors and allows the collection of broken bones from defeated players in player-versus-player combat for use as currency. At level 2, gives you the ability to fall from heights unharmed and breathe underwater, as well as opening up specific PvP quests. At level 3, it reduces the damage you take outdoors by half when you’re below 35 percent health, and allows access to the Highmaul Coliseum gladiator tournament.
Barn: At level 1, allows you to capture game animals for leather and fur used in leatherworking and tailoring profession recipes. At level 2, allows you to capture animals that give rare meats to create powerful food (which increases character stats). Level 3 allows you to capture elite beasts that provide savage blood, a crafting material for high-level armor and weapons.
Lumber Mill: At level 1, allows you to mark small trees in the game world to be turned into garrison supplies, which are used for crafting, creating buildings and running some follower missions. Level 2 allows you to mark medium trees for more supplies. Level 3 allows you to mark large trees.
Trading Post: At level 1, a merchant shows up daily selling trade goods, and you can trade crafting reagents for garrison resources. At level 2, it allows you to trade with different vendors and put an auctioneer in your garrison. At level 3, it increases the reputation you gain with NPC groups in Draenor by doing quests or killing creatures by 20 percent.
Above: The Enchanter’s Study offers players the ability to disenchant items into the materials it takes to add enchanting enhancements to their gear, even if their character doesn’t know the profession. It’s a small-plot garrison building.
Small buildings (10 available, and you may build three)
Almost all small buildings are profession buildings, and offer the same bonuses. At level 1, you may create items from that profession and place work orders for profession supplies by trading in raw materials. At level 2, you can place a follower that is proficient in that profession in the building, giving a related bonus, and create three work orders instead of one. At level 3, you can create five work orders at once.
These bonuses apply to the following buildings: the Engineering Works (engineering); Gem Boutique (jewelcrafting); Alchemy Lab (alchemy); Scribe’s Quarters (inscription); Tailoring Emporium (tailoring); The Forge (blacksmithing); The Tannery (leatherworking).
The three with different bonuses are:
At level 1, the Enchanter’s Study (enchanting profession building) gives players the ability to disenchant items into materials that can be used to put enchanting enhancements on other gear, even if they don’t have enchanting as a skill. (Other bonuses remain the same.)
The Salvage Yard isn’t a profession building. It offers players the ability to recover salvage from follower missions at level 1; to recover follower items in the salvage at level 2; and greatly increases the chance of getting salvage at level 3, also adding the chance to get player character items.
The Storehouse: Level 1 gives you bank access inside your garrison and increases the work orders your other buildings do by 1 a day. Level 2 gives you access to the bank run by the guild of players you belong to, if any. Level 3 gives you access to large-scale Void Storage (Warcraft’s “deep freeze” for items you don’t need for a long time) and transmogrification from within your garrison, and increases work orders in all your buildings by 2.
