Health regeneration

Health Regeneration (also known as HP5) is a stat similar to mana regeneration which determines the amount of health a champion regenerates over a five-second period. This happens in half-second intervals. Health regeneration is considered to be a form of healing for the purposes of healing increases or decreases, and for the sake of the "Healing Done" stat at the end of game screen. Each champion starts with a certain base rate of health regeneration, which increases by a small amount at each level-up. It can be further increased by a variety of items, abilities, masteries, runes and neutral buffs, as detailed below. Health regeneration stacks additively, meaning that each bonus point acquired directly affects its statistic. This is true whether the bonus is a flat value or percentage-based.
