Health Regeneration
From Paragon Wiki Archive
Health Regeneration is the rate at which Health is replenished over time for players and critters. A higher Regeneration rate increases the amount of Health regained at each tick, while a lowered Regeneration has the opposite effect.
Regeneration is based on percentages, not fixed amounts of health points (HP). Thus, raising your maximum health through accolades, set bonuses, and Dull Pain type powers will also improve the amount of health gained each tick.
Many players confuse Regeneration with Recovery, which refers either to the speed players regain their Endurance; or with the Regeneration powerset for Scrappers and Stalkers, which has several powers which improve health regeneration.
