Health Regeneration determines the amount of health a unit regains each second. It is shown as a small number with a + sign at the right side of the unit's health bar.

Heroes also gain health regeneration amplification based on their Strength attribute symbol.png strength. Each point of strength amplifies the hero's health regeneration by 0.55%.

Health regeneration heals the unit in 0.1 second intervals. This rate cannot be changed by anything. Health regeneration has no cap, although the HUD does not show regeneration over 1000 health per second.

Health regen amplification[edit]

Each point of Strength attribute symbol.png strength amplifies the hero's health regeneration by 0.55%, stacking additively with each point of strength. The hero's current health regeneration gets multiplied by the total amplification the hero has.

For agility and intelligence heroes:

Health Regeneration = (Base + Sum of Flat Bonuses) × (1 + strength × 0.0055)

For strength heroes:

Health Regeneration = (Base + Sum of Flat Bonuses) × (1 + strength × 0.0055 * 1.25)

Besides strength, the following abilities also amplify health regeneration.

Modifying health regeneration[edit]

Just like for health, there are many abilities and items which can change how fast a unit regenerates health. Most of them increase health regeneration rate by adding a flat bonus, but some also increase it based on certain things, like health or attributes. They can be passive bonuses which grant a permanent bonus or be conditionally activated, or be short, but grant a strong bonus.
