The result of the battle is affected by numerous factors, including the type of troops, active boosts, the Hero's and Shaman's bonuses, Skills, Reputes, Town Skins, learned Knowledge, and so on.

Please note: at the time of the battle, some of the bonuses may have expired, for example, the bonuses from a boost or a Repute. Alternatively, the wrong piece of equipment may have been equipped on your Hero or a Shaman accidentally.
