Aesir belong to various Elements, each of which has its own advantages. There are three Elements in total: Earth, Fire, and Ice.

Earth Aesir give a bonus to troop offense against Fire Aesir. Fire Aesir give a bonus to offense against Ice Aesir, and Ice Aesir give a bonus to offense against Earth Aesir.

Pay attention to the Element of your enemy's Aes and summon an Aes of the opposing Element. This will grant you a substantial advantage over your enemy. To find out which Aes your opponent has summoned, go to the Jarl information window.

Please note: the Disguise item hides information about the summoned Aes, Shaman, and equipment on the Hero.
