Boosts are special items that temporarily improve certain characteristics. You can find all the necessary information about them in the Boosts window. For example, there you can find out which bonuses are currently active and how long they will remain in effect.

There are five tabs in the Boosts window: Military, Resources, Development, Hero/Shaman, and Favorites. To get quick access to boosts and Aesir, add them to Favorites by hitting the star.
