vitality 'vit stat'
Vitality is a measure of a character's energy, aerobic fitness, and vim. A vital character will become exhausted less quickly, and thus will regenerate hit points and move points faster. It will also help characters to snap out of it when they have been dazed by a spell or a blow. Vitality is the prime stat of such skills as Berserk and Fast Healing, and of the class Gladiator.
