This page shall help to decide which levels to aim for and which Great Building to level next. It is reasonable to compare them among each other and by attack boost per their cost in Forge Points. However, each level of a Great Building costs a specific amount of Forge Points and each Great Building can be built only once. There are two main categories of buildings to be considered for their attack boosts: Great Buildings and Special Buildings.Īs for space efficiency, Great Buildings are the most efficient attack boost buildings in the game since the player can increase their boost arbitrarily by leveling them up. This page shall help the player to decide which buildings to focus on (possibly in combination with the Forge Point Building Efficiency page). Especially the introduction of the Antiques Dealer allows the player to set their focus on getting buildings or upgrade kits of older event buildings. There are no upgrade kits for those buildings instead players had to trade in the previous version of the building to receive the next version, as part of the event questline they were part of.Forge of Empires gives the player the option to choose from a variety of buildings that provide the attacking army with both Attack Boost and Defense Boost. Although they can be upgraded, the mechanics are different. Some buildings can be upgraded without the upgrade kit, for example the Confectionary and the Tree of Love. Shrink Kits are in essence like upgrade kits however they only reduce the size of the buildings and do not increase the production properties. Note that the upgraded building will be from your current era, even if the old one was from one of the earlier ages.

Buildings that become larger in size will be stored, while buildings that keep the same size or become smaller will stay in your city.

After the upgrade kit has been used, some buildings will be stored in the inventory and must be placed in the city again manually others will be placed directly on the same spot in your city, and the production timer will not be reset.

To upgrade a building, the upgrade kit must be used on the corresponding building that is already situated in the city. Upgraded buildings gain better properties with each level. The Upgrade Kit is an item that can be used to upgrade an eligible special building to a higher level.
