Vitality is the measure of life in Nexus. It is similar to "hit points" in most games.
Vitality is increased with each increase in insight. After the 99th insight, players do not gain levels in a normal fashion. However, they can choose to increase their vitality by selling experience at the Shadow Dragon NPC in south Buya or south Kugnae or north Nagnang
