Mana regeneration

Mana Regeneration (also known as Mp5 or mana per 5 seconds) is a statistic that determines the amount of mana that a champion regenerates over a five second period. Each champion starts with a certain rate of base mana regeneration. This statistic scales additively; meaning that each bonus point acquired directly affects the statistic.
