In group play found in many role-playing games, the role of the tank is to protect players that are low-armor or low-health classes (such as archers or mages). The role of a tank is typically to survive an oncoming attack, and then ensure that they are the target of the incoming attack. It then falls upon a healer unit (in large-scale play, often specifically assigned to the role, with spells specializing in high healing output over one or two targets) to restore the tank unit's health so they do not die and allow them to take the next attack.
