Mana (also known as MP, which is short for mana points) represents the magic power of a unit. It is used as a cost for the majority of active and even some passive abilities. Every hero has a base mana pool of 75_MP, while most non-hero units only have a set mana pool if they have abilities which require mana, with a few exceptions. These values cannot be altered. This means that a hero's maximum mana cannot drop below 75_MP.

Because each point of intelligence increases a hero's mana by 12_MP, a hero's mana pool scales upwards with their intelligence points. Similarly, because every hero has some measure of intelligence growth per level, all heroes gain more and more mana as they continue to level up. A hero's base intelligence cannot drop below 1; however, it is possible to achieve 0 intelligence with the help of negative bonus intelligence.

• Total hero mana can be defined as
  • Base Mana
    • + (12 ×  Intelligence)
    • ± Flat Bonus Mana Values
  • × % Bonus Current/Max Mana Values

Display

Blue bar shows mana. Right number is mana regeneration.

The mana of a unit is displayed in the HUD. For some units, it also may be displayed in the game world.

HUD Mana bar

The mana bars of enemy heroes and creep-heroes are not visible above their head.

Mana of the selected unit is displayed in the HUD as a blue bar at the bottom of the screen. The left number at the center of the bar is the unit's current mana points and the right number is its maximum mana points. Though not displayed in the HUD, a unit's total mana does use decimal numbers. The visible numbers in the HUD are always rounded up.

The mana regeneration value is visible on mana bars in the HUD of every unit. Though the HUD shows only one decimal for mana regeneration, it uses more decimals. The value in the HUD is rounded up.

Over-head Mana bar

The mana bar of heroes and creep-heroes are displayed right above their heads, below their health bar. Even when a creep-hero has no mana pool, a mana bar is still drawn below their health bar above them. Other units do not have an overhead mana bar.

There are no different types of mana bars. They do not have lines like the health bars and do not differ from each other in any way.

Modifying Mana

Some heroes, units (neutral creeps and summoned units) and items have abilities that can affect the current and maximum mana pool of units.

Restoring Mana

Just like healing health, a unit's current mana can be increased by many abilities, mostly referred to as restoring mana.

Restoring mana cannot increase the unit's mana beyond its maximum mana pool. Certain abilities may restore mana in a burst on a target, restoring an amount of mana in an instance, or restore mana over time, where the amount is split up in multiple instances. The difference between restoring mana and regenerating mana is that restoring is independent from the regeneration ticks. Unlike regeneration, the restore intervals can vary. Restoring mana is not reflected in the regeneration number on the mana bar.

Removing Mana

Most active and some passive abilities need mana in order to be used. This includes item abilities. The mana cost of such are displayed at the bottom left corner of the ability icon in the HUD, and once more inside the ability description in the bottom left corner. Most abilities have a fixed amount of mana cost, but some are dynamic (e.g. based on mana pool, or costing mana over time).

Besides using mana, there are also ways to offensively make units lose mana unvoluntarily. This act may be referred to as burning if it causes damage based on mana removed, draining if the mana is stolen and transferred to another unit, or removed if the mana is simply removed without other effects.

Setting Mana

Besides restoring and removing mana, a unit's mana may also be directly altered by setting it to certain values. Mana altered this way is neither registered as a mana restorement, nor as mana removal, and therefore is ignored by anything that reacts on restored or removed mana. It can never set the mana beyond the unit's maximum mana.

  Fully refills the targeted creep's mana pool upon persuading.

Maximum Mana Affecting Abilities

Besides intelligence and raw bonuses from items, there are only very few abilities which can alter a unit's maximum mana.

This list does not include intelligence affecting sources.

Items

Many items grant their owners a mana bonus, increasing their maximum mana when equipped, either by increasing their intelligence, or by just giving them a flat bonus. In either case, the current mana percentage stays the same.

The following items increase a unit's maximum mana pool. The effects are limited to the item's owner, which must have the item equipped.

Mana Restore Manipulation

Main Article: Restoration Manipulation

Mana restore manipulation refers to any form of amplification and reduction applied to mana restoration. Mana restore manipulations affect every ability listed under mana restoring.

Mana Restore Manipulation Sources

^2a Requires Aghanim's Scepter.

Mana Loss Manipulation

Several abilities are able to reduce the amount of mana a unit loses. This includes the mana cost of abilities, and mana removed, burned or drained by abilities. Mana Loss Manipulation stacks multiplicatively.

Mana loss manipulation has no effect on mana regeneration, so if the regeneration should have a negative value, mana loss reduction does not affect it.

It does not affect mana changes caused by losing or gaining intelligence. Current mana percentages are kept equal upon gaining or losing intelligence, regardless of mana loss reductions. It also has no effect on mana setting effects.

When an ability has extra effects based on the mana loss, these extra effects are not affected by mana loss reduction. For example, Mana Break abilities deal full damage, despite burning less mana and mana draining effects still restore the same amount, despite their targets losing less mana. However, mana loss reduction is applied before the ability is actually cast, causing for example, Nether Ward to deal reduced damage.

On-restore Effects

Similar to how some abilities react on a unit getting damaged, some abilities react on a unit getting mana restored, or on a unit regenerating mana. Only mana gain that is classified as a mana restoring, and mana regeneration trigger on-restore effects. Mana gained in other means (e.g. getting mana set) does not trigger it.

Besides mana restore amplifications, the following abilities react on restoring and regeneration.

• Io - Tether
  
  Restores the tethered ally's mana by a percentage of restorement and regeneration the caster receives, whenever the caster gets restored or regenerates mana.

These abilities have effects that are based on maximum mana.
