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 bonus health regeneration based on their Strength attribute symbol.png strength. Each point of strength increases the hero's health regeneration by 0.1.

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 regeneration is affected by heal manipulation. When increased or reduced, the HUD shows the increased/reduced values.

Base health regeneration[edit]

Most units have a set base health regeneration, differing from unit to unit. Most heroes have no base regeneration, while some non-hero units may not have any base regen, but most of them do.

Modifying health regeneration[edit]

Just like for mana, 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.

Health regen manipulation[edit]

Health regen manipulation refers to any form of amplification and reduction applied to health regeneration.

The following abilities provide health regen manipulation

Similar to heal amplification, when a unit is affected by less than -100% regen amplification, its regeneration becomes degeneration with negative value on the HP bar corresponding to the percentage over -100%. This degeneration is not lethal.
