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 gain mana regeneration based on their Intelligence attribute symbol.png intelligence. Each point of intelligence increases the hero's mana regeneration by 0.05.

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

Base mana regeneration[edit]

Most units with a mana pool have a set base mana regeneration, differing from unit to unit. Most heroes and some non-hero units have no base mana regeneration.

Mana regen amplification[edit]

Mana regeneration is affected by mana restore manipulation. However, mana regeneration also has its own amplifier, increasing it the same way as mana restore amplification does.

Mana regen amplification stacks additively with the amplification provided by mana restore amplifications, meaning if both are present, they do not amplify each other.

Modifying mana regeneration[edit]

Just like for health, 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.
