Stamina is an optional feature in Viking Conquest. You may switch stamina on or off when you begin a new game.
Stamina determines how far you can run and how many times you can swing your weapon before you are exhausted. When you get exhausted, you can no longer run and all your weapons will inflict only half of their normal damage.
The amount of stamina available is based on the agility attribute and athletics skill.
Unlike health, there isn't a visible bar, but underneath the health bar, the amount of available to you is displayed as high, normal, tired, very tired, or exhausted. When you become exhausted, a message appears on the screen with the other combat information. You start every battle with a high amount of stamina, and if you are slowly moving around or standing still, you will regain stamina.
The presence of a stamina indicator can sometimes also serve as a warning in cases where there will be a potential fight without the game explicitly telling you so.
