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 80MP, 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 80MP.
Because each point of intelligence increases a hero's mana by 12MP, 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
- Base Mana
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.

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.

Talents[]
- Increases the max mana capacity, but keeps the current mana percentage.
- The following values exist:
- 100/125/150/175/200/225/250/275/300/350/400/500/600/700/800/1000
No hero has this talent.
Mana Restore 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.
- 1 Requires talent.
- 2a Requires Aghanim's Scepter.
- 2b Requires Aghanim's Shard.
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.
-
Mana Loss Reduction: 30%
Duration: 50 -
Mana Loss Reduction: 5%
Affects the item owner.

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.
Abilities Modified by Mana[]
These abilities have effects that are based on maximum mana.
Besides illusions, whose current health and mana depend on the current health and mana of the unit they are based on, the following abilities have effects that are based on current mana.
These abilities have other mana-based effects as well.
-
Damage per Missing Mana: 0.8/0.95/1.1
Deals damage to the target and in an area around it based on how much mana the target is missing. -
Mana Difference Damage Multiplier: 0.4 ( 0.55)
Deals damage to everyone within the area based on the mana difference between the caster and the hit enemy heroes. -
Damage per Used Mana: 1/1.2/1.4/1.6 (
Bonus Mana: 0/50/100/150/2002.75/2.95/3.15/3.35)
Deals damage to any nearby enemy that dares to spend mana in any way.
Mana Regeneration[]
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.
Recent Changes[]
- Mana cost reduction now stacks multiplicatively.
- Fixed mana restore manipulation and mana regen manipulation, to not allow negative mana restore and mana regeneration.
- Heroes can now have non-standard base mana regeneration values.
