Endurance is a primary attribute and a significant factor in determining one's Health. With every increase in level ten percent of the Nerevarine's Endurance is added to total Health, including any Endurance being added during the level-up, but excluding magical bonuses from all sources. This attribute is also one of the four factors that determine total Fatigue, and reduces Fatigue loss during strenuous physical activities such as combat and running. For each 2 points of endurance one starts off with, they also get one health the same goes with strength.
