Bonus Mana Regen required to regenerate max Mana in a given time (0.9 base)

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

Heroes also gain mana regeneration amplification based on their Intelligence attribute symbol.png intelligence. Each point of intelligence amplifies the hero's mana regeneration by 2%.

Mana regeneration restores the unit in 0.1 second intervals. This rate cannot be changed by anything. Mana regeneration has no cap, although the HUD does not show regeneration over 500 mana per second.

Mana regen amplification[edit]

Each point of Intelligence attribute symbol.png intelligence amplifies the hero's mana regeneration by 2%, stacking additively with each point of intelligence. The hero's current mana regeneration gets multiplied by the total amplification the hero has.

Mana Regeneration = (Base + Sum of Flat Bonuses) × (1 + intelligence × 0.02)

Besides intelligence, the following abilities also amplify mana regeneration.

Modifying mana regeneration[edit]

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