▶️ Life becomes death becomes new life. As it should be. — Treant Protector

”

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 120_HP. This value exists for all heroes and cannot be altered. This means that a hero's maximum health cannot drop below 120_HP.

Because each point of strength increases a hero's health by 22_HP, a hero's health pool scales upwards with their strength points. Similarly, because every hero has some measure of strength growth per level, all heroes gain more and 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.

Display

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

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

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 ocre 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 ocre, 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 250_HP and a thick line for every 1000_HP. Most of these health display options can be configured to personal preference by using the dota_health_per_vertical_marker console command.

Health Bars
	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 have an identical health bar as heroes, with the only difference being a darker green and red tone and no level plate.
	Creeps have a smaller health bar with a darker green and red tone, like creep-heroes. Creep health bars have no lines.
	Neutral creeps have the same health bars as other creeps. However, in spectator mode, they are ocre, instead of red.
	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 ocre for spectators.
	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.
	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 is enabled.
	Towers and barracks have shorter health bars with bright colors. Towers have shorter bars than barracks. The shield icon appears when Backdoor Protection is enabled.
	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.

Healing

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:

There are several other abilities which 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 which react on healing, like Ice Blast, False Promise and Tether.

Damaging

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 on healing and damage. It can also never be lethal, and can never set the health beyond the unit's maximum health.

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 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.

Health Granting Items

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.

Talents

The following heroes have a talent that grants them a flat health bonus.

Bonus	Level 10		Level 15		Level 20		Level 25
	Left	Right	Left	Right	Left	Right	Left	Right

Heal Manipulation

Heal manipulation refers to any form of amplification and reduction applied to health restoration. Heal manipulations affect every ability listed under healing.

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.

Besides heal amplifications, the following abilities react on healing and regeneration

• Io - Tether
  
  Heals the tethered ally by a percentage of heals and regeneration the caster receives, whenever the caster gets healed or regenerates 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. Each point of strength increases the hero's health regeneration by 0.1_HP.
