The Barracks is the only advanced building currently available in the game. To first build it you must have your Stronghold at level 10, and another building at at least level 5. When you select the building you are then given the opportunity to convert it into this advanced building. After doing so, you may then convert the building between the original, and the barracks, at will, for no cost, though you do need an available worker to accomplish this simple, 5 second task. It is recommended that you use one of your forges for this purpose.
The barracks is used to level up troops.
Troop Upgrades & Building Upgrade Costs
The level of the barracks building dictactes the level to which you are permitted to raise your troops. Leveling troops is done in the same manner that leveling heroes is done: you sacrifice some troops to level up others.
