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. Each point of strength increases the hero's health regeneration by 0.1HP.
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 +1000HP per second.
Health regeneration is affected by heal manipulation. When increased or reduced, the HUD shows the increased/reduced values.
| Attribute | Bonus Health Regeneration |
|---|---|
| Strength | +0.1HP |

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 regeneration, but most of them do.
Heroes[edit]
Creeps[edit]
Summons[edit]
None of the summoned wards have base health regeneration. All other summoned units have the following base regen:
| Summons | Health regen |

Modifying Health Regeneration[edit]
Just like for mana regeneration, 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.
