Attack Boost for Attacker
Defense Boost for Attacker

Forge of Empires gives the player the option to choose from a variety of buildings that provide the attacking army with both Attack Boost for Attacking Army Attack Boost and Defense boost for attacking army Defense Boost. Especially the introduction of the Antiques Dealer allows the player to set their focus on getting buildings or upgrade kits of older event buildings. This page shall help the player to decide which buildings to focus on (possibly in combination with the Forge Point Building Efficiency page). There are two main categories of buildings to be considered for their attack boosts: Great Buildings and Special Buildings.

As 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. However, each level of a Great Building costs a specific amount of Forge Forge Points and each Great Building can be built only once. It is reasonable to compare them among each other and by attack boost per their cost in Forge Points. This page shall help to decide which levels to aim for and which Great Building to level next.

Special Buildings, on the other hand, can be built in any amount that fits into the space of the player's city. They do not have building costs but their attack boost cannot be increased arbitrarily. They are best compared in attack boost per the space they use up. As for some of the buildings their boost increases with the age they are in it can be profitable to age them up with a One Up KitOne Up Kit or a Renovation KitRenovation Kit. This page shall help to decide when to most efficiently age up Special Buildings for their attack boost.



Cost efficiency for Great Buildings[]

Work in progress.


Space efficiency for Special Buildings[]

The following table considers for the efficiency only the space the building itself needs. Please keep in mind though that the streets needed to connect the building are also to be considered for the efficiency. If you consider the needed street connection, this would increase the efficiency of big buildings as these generally are connected to relatively fewer streets than smaller event buildings, and also the efficiency of decorations.

Increased space efficiency for Building Sets[]

From the time they are released Building Sets usually come with a standard layout proposed by InnoGames. In that standard layout all buildings of the set appear exactly once and each of them has the full production bonus for the number of different adjacent buildings of the set. [1]

However, by composing a different layout with possible duplicates or non-occurrences of specific buildings from the set, it is possible to achieve significantly higher attack bonuses. For reference, the raw attack values of the relevant parts are listed here. A tool for composing new layouts can be found here.

  1. ↑ As an exception the Winter Village Set Icon Winter Village Set and Winter Bakery Set Icon Winter Bakery Set standard layouts do not have full bonuses for all buildings.
