Mana

Mana is used to cast most active abilities. All units that use Mana in some way have a maximum amount of Mana they can have at one (Max Mana) and cannot use an ability if they do not meet the Mana Cost. Mana can be restored via Mana Regeneration (measured in Mana gained/second) or certain Mana restorers. Heroes gain 13 Max Mana per each point of Intelligence.

Mana Regeneration

How mana regeneration works.

All heroes have a base Mana Regeneration of +0.01 Mana/sec
Each point of Intelligence increases a Hero's base Mana Regeneration by 0.05
Some non-hero units that have Mana may or may not have a base Mana Regeneration
Mana Regeneration can be increased by items and abilities that grant either percentage Mana Regeneration or flat Mana Regeneration
Percentage Mana Regeneration increases your base Mana Regen by that percentage
Flat Mana Regeneration granted is not multiplied by percentage Mana Regeneration
