Health regeneration

Health Regeneration (also known as Hp5 or health per 5 seconds) is a statistic that determines the amount of health that a champion regenerates over a five second period. Each champion starts with a different rate of base health regeneration. This statistic scales additively; meaning that each bonus point acquired directly affects the statistic and is not affected by diminishing returns.
