Mana regeneration refers to the mana that a class restores after losing a given amount of mana. Mana can be gained via two ways: passively, and through regeneration models. Passive mana regeneration is global for all classes, and is characterized by a fixed amount of mana gained every couple of seconds. Its effects are also more pronounced outside of combat than within. Regeneration models are unique to each individual class and are independant of class model. Before we get into each of the respected mana models, let's first look at how mana regen behaves in combat:
