Surrender is act of a hero during combat, where he pays the enemy hero an amount of gold in order to let him keep his artifacts and let his troops a safe passage. Surrendering cannot be prevented, if the hero has enough gold. A hero may surrender at any point during battle if it is the hero's turn to act. He may also surrender before combat during his Tactics Phase if such a phase occurs. However, a hero can only surrender to another hero, which means that he cannot surrender to a group of wandering creatures. A hero cannot surrender when defending a siege, or when the enemy hero wields Shackles of War.
The surrendered hero will appear in tavern immediately or at beginning of the next day. This happens also in the case where a hero surrenders after the player's seventh day of the week has passed, meaning that instead of having two new hero recruits, the other one is the hero surrendered in the past day.
The amount of gold needed for surrendering is (by default) half the hiring price of the (remaining) creatures; resource cost are not included. If the hero does not have enough gold to pay for his (remaining) army, he cannot surrender. The amount of gold needed to surrender can be decreased with Diplomacy secondary skill and with artifacts. Diplomacy reduces the cost by 20%, 40% or 60%, and artifacts Ambassador's Sash, Diplomat's Ring and Statesman's Medal each reduces the cost by 10%.
