Health (also known as HP, which is short for health points) represents the life force of a unit. When a unit's current health reaches 0, it dies. Every hero has a base health pool of 20HP. This value exists for all heroes and cannot be altered. This means that a hero's maximum health cannot drop below 20HP.

Because each point of strength increases a hero's health by 22HP, a hero's health pool scales upwards with their Strength attribute symbol strength points. Similarly, because every hero has some measure of strength growth per level, all heroes gain more health as they continue to level up. A hero's base strength cannot drop below 1; however, it is possible to achieve 0 strength with the help of negative bonus strength.

  • Total hero health can be defined as
    • Unmanipulated Health
      • Base Health = 20HP
      • + 22 × Strength attribute symbol (Base Strength + (Level - 1) × Strength Gain ± Bonus Strength)
      • ± Flat Bonus Health Values
    • × % Bonus Current/Max Health Values


Health and mana

Green bar shows Health. Right number is health regeneration.

The health of a unit is displayed in the game world. It also is displayed again in the HUD upon selecting a unit.

HUD Health Bar[]

Hud health bar comparison

Default health bar compared to colorblind mode
In colorblind mode, all HUD health bars are turned blue.

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

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

Over-head Health Bar[]

HP Comparison

Pudge with six different amounts of health.

The health bar in the game world are displayed right above every unit's head. Unlike the health bar in the HUD, the bar's color change based on alliances. It is green when it is an allied unit and red when it is an enemy unit (including neutral creeps). For spectators, neutral creeps' health bar take an ocher color. In colorblind mode, allied and the own overhead healthbars are blue, and in Differentiate Ally Healthbars mode (in settings), allied overhead health bars are ocher, while the own health bar stays green.

There are 4 different types of health bars: Hero, creep-hero, building and creep health bars. Their differences lie in their color shade, size and other small differences. Heroes and creep-heroes have vertical lines in them which divide their health pool to make it easier to determine their exact amount of health. By default, their health bars display a thin line for every 250HP and a thick line for every 1000HP. Most of these health display options can be configured to personal preference by using the dota_health_per_vertical_marker console command.

Health Bars
Heroes health bar
Hero health bars are bright green or red and segmented by lines to make it easier to guess their health values. By default, their health bars display a thin line for every 250HP and a thick line for every 1000HP. Heroes also have a level plate to the right of the bar and have a thick border around them.
Creep-heroes health bar
Creep-heroes have an identical health bar as heroes, with the only difference being a darker green and red tone and no level plate.
Creeps health bar
Creeps have a smaller health bar with a darker green and red tone, like creep-heroes. Creep health bars have no lines.
Neutrals health bar
Neutral creeps have the same health bars as other creeps. However, in spectator mode, they are ocher, instead of red.
Roshan health bar
Roshan icon Roshan has the same health bars as other creeps, but it is much bigger, and uses a brighter red, similar to that of heroes. Like neutral creeps, Roshan's health bar appears ocher for spectators.
Couriers health bar Animal Courier Radiant minimap icon Couriers health bars are brighter than those of creeps, but darker than heroes. They also have the default courier icon on the left side of the bar.
Ancients health bar
Both ancients have a very large health bar with bright colors. The bar and their borders are thicker. The shield icon appears when Backdoor Protection icon Backdoor Protection is enabled.
Towers health bar
Towers and barracks have shorter health bars with bright colors. Towers have shorter bars than barracks. The shield icon appears when Backdoor Protection icon Backdoor Protection is enabled.
Misc buildings health bar
Effigy buildings have very short health bars with dark colors. These buildings do not have the backdoor protection icon, even when it is enabled.

Modifying Health[]

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


Increasing a unit's current health is most commonly known as Healing. Healing cannot increase the unit's health beyond its maximum health pool. Spells may apply a burst of heal on a target, which restore an amount of health in an instance, or heal the target over time, where the amount is split up in multiple instances. The difference between a heal and regeneration is that a heal is independent from the regeneration ticks. Unlike regeneration, their heal intervals can vary. A heal is not reflected in the regeneration number on the health bar.

Besides lifesteal and spell lifesteal, the following abilities heal units:

1 Requires Talent talent.
2a Requires Aghanim's Scepter icon Aghanim's Scepter.
2b Requires Aghanim's Shard icon Aghanim's Shard.

The following healing sources heal based on damage dealt, amplifying or reducing the damage affects the healing value. The healing value itself can still be subjected to heal manipulation.

1 Requires Talent talent.
2a Requires Aghanim's Scepter icon Aghanim's Scepter.
2b Requires Aghanim's Shard icon Aghanim's Shard.

There are several other abilities that are able to increase a unit's current health, but these effects do not count as healing. This means, similar to how damage flagged as HP Removal does not react on on-damage effects, these abilities fully ignore abilities that react on healing, like Ice Blast icon Ice Blast, False Promise icon False Promise and Tether icon Tether.


  • Bloodrage icon
    Enemy Max Health as Damage/Lifesteal: Upgradable by Aghanim's Shard. 30
    Heals based on the attacked unit's maximum health, it does not depend on damage dealt to the target. It is affected by lifesteal manipulation. The damage cannot crit, cleave, or lifesteal with other sources of lifesteal than its own.
  • Feast icon
    Lifesteal: 1.6%/2.2%/2.8%/3.4% (Talent 2.8%/3.4%/4%/4.6%)
    Heals based on the attacked unit's maximum health, it does not depend on damage dealt to the target.
  • Ransack icon
    Hero Health Steal: 9/12/15/18 (Talent 17/20/23/26)
    Creep Health Steal: 3/5/7/9 (Talent 11/13/15/17)
    Heals all Meepos by a set amount. The actual damage dealt to the target does not matter.

Min Health[]

Min health demo

Lina minimap icon Lina casting Laguna Blade icon Laguna Blade on a low health Dazzle minimap icon Dazzle affected by Shallow Grave icon Shallow Grave and Blade Mail icon Blade Mail.
Lina takes the full Laguna Blade damage.

Minimum Health, also prevents a unit from dying like damage negation. However, instead of directly reducing or negating damage, this mechanic manipulates the health of the unit. The MODIFIER_PROPERTY_MIN_HEALTH property prevents a unit's health from dropping below the value it is set to. It does not affect the damage itself, meaning on-damage effects still reacts on the full damage, and not how much damage was dealt with effectively, so they can be triggered normally.

Does not prevent instant kill sources (e.g. Culling Blade icon Culling Blade) in any way.

Min health sources have the following priority:

Upgradable by Aghanim's Scepter. Reincarnation icon Wraith DelayShallow Grave icon Shallow Grave / Battle Trance icon Battle Trance

1 Requires Talent talent.
2a Requires Aghanim's Scepter icon Aghanim's Scepter.
2b Requires Aghanim's Shard icon Aghanim's Shard.


Main Article: Damage Types

Just like how there are ways to increase a unit's current health, there also are ways to do the opposite, reduce a unit's current health, with the use of damage. Unlike heals, there are multiple types of damage, which act differently based on the defenses of the unit, mainly armor and magic resistance.

Setting Health[]

Besides healing and damaging, a unit's health may also be directly altered by setting it to certain values. Health altered this way is neither registered as a heal, nor as damage, and therefore is ignored by anything that reacts to healing and damage. It can also never be lethal, and can never set the health beyond the unit's max health. When casting the following abilities with lesser health than the health cost, the caster's goes down to 1HP.

HP Removal is not the same as Setting Health. HP Removal is still damage, but flagged to bypasses several but not all on-damage effects, and can still be lethal.

Maximum Health Affecting Abilities[]

Besides Strength attribute symbol strength there are a few other ways to increase or alter a unit's maximum health. Usually, when increasing or reducing a unit's maximum health via other ways than strength, its current health percentage stays the same, so that no healing effect occurs.

The following abilities are able to alter a unit's maximum health pool (sources of strength are not listed):

1 Requires Talent talent.
2a Requires Aghanim's Scepter icon Aghanim's Scepter.
2b Requires Aghanim's Shard icon Aghanim's Shard.


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

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

Health Freeze Sources

On-heal Effects[]

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

  • Tether icon
    Heals the tethered ally by a percentage of heals and regeneration the caster receives, whenever the caster gets healed or regenerates health.
  • False Promise icon
    Only registers actual heal and regeneration. Ignores other ways of gaining health.

Health Regeneration[]

Main Article: Health regeneration

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

Heroes also gain bonus health regeneration based on their Strength attribute symbol strength. Each point of strength increases the hero's health regeneration by 0.1HP.
