Health

Health measures the amount of damage that can be taken before dying, and is fundamental to all heroes and units. Units and players with health are allowed to interact with the game, and consequently when your health drops to zero you are disabled from playing until respawning.

Maximum Health

Kelvin's starting base health at  0

The formula for maximum health $H{P}_{Max}$ is:

$H{P}_{Max}=(H{P}_0+N_{PI}\times P{I}_{HP})\times (1+\sum H{P}_{Shop})+\sum H{P}_{Bonus}$

where $H{P}_0$ is hero-specific starting base health, $N_{PI}$ is the number of Power Increases earned, $P{I}_{HP}$ is hero-specific added base health from each power increase, $H{P}_{Shop}$ are implicit base health percent increases from Vitality items, and $H{P}_{Bonus}$ are bonus health flat increases from various sources. Note that the max health presented in-game is rounded up to the nearest integer.

Base Health

Kelvin's base health at  20.0k

Base health is the sum of starting base health and added base health from power increases. It is scaled by the inherent increased base health stats of Vitality items. Different heroes have different amounts of starting base health and added base health from power increases.

Increased Base Health

Each Vitality item purchased grants a percentage increase to base health based on its tier. Higher tier items grant larger percentage increases. These increases are summed together before being multiplied with base health.

Vitality Item Tier	% Increased Base Health
1	11%
2	14%
3	17%
4	20%

Bonus Health

Survival power-up located in the training map

Bonus health comes from a variety of sources:

• Items are the most common source of added bonus health. Bonus health can be found on all three item types, but Vitality items tend to provide the largest amounts.
• Golden statues occasionally drop small but permanent added bonus health buffs: +20 before 10 minutes, +30 between 10 and 30 minutes, or +40 after 30 minutes.
• The Survival Powerup immediately grants +400 bonus health, but only for 160 seconds or until death.
• The Rejuvenator immediately grants +200 bonus health, but only for 3 minutes or until death.

Bonus Health is not scaled by increased base health. Bonus health is added after the increased base health multiplier has been applied to base health.

Miscellaneous Health Modifiers

With the purchase of Glass Cannon, the hero's max health is reduced by 15% after the above calculations.

Example

Kelvin begins the game with 600 Base HP. If Kelvin purchases the tier 1 vitality items Extra Health and Extra Stamina, the first of which also grants 160 bonus health, his max health becomes:

$H{P}_{Max}=600\times (1+(0.11+0.11))+160=892$

If Kelvin then earns a power increase, his base health increases by 50, and his max health becomes:

$H{P}_{Max}=(600+50)\times (1+(0.11+0.11))+160=953$

Regaining Health

Main articles: Healing, Health Regen

From the start of the match, heroes will regenerate health slowly over time, typically 2 HP per second. This rate can be increased by purchasing items such as Extra Regen and Fortitude. Health can be regained quickly by returning to the spawn room of the team's base. Various hero abilities can heal, such as Dynamo's Rejuvenating Aurora. Sources of spirit and bullet lifesteal grant heroes the opportunity to regain health by dealing the respective damage type.

Health Bars

Examples of how health and shields are displayed in the alternate health bar

Health Bars are visual indicators of a hero's current health, located just above each hero. Health bars consist of filled rectangles, arranged in rows of up to ten. Enemy heroes are displayed with orange rectangles, while allied heroes use an off-white color. As the hero loses health, the rectangles deplete horizontally. Each full rectangle represents 100 health, and each full row represents 1000 health.

The small yellow and blue bars above the health bar represent bullet shields and spirit shields, respectively.

Alternate health bar

The alternate health bar is an experimental bar that can be tested by players. This bar always has the same size, and the health count is displayed as markings instead of rectangles. One marking represents 100 health, and a line represents 500 health (from left to right).

This health bar also indicates when other players have ultimates ready, represented by an eye icon that fills up when the ultimate is recharged. Bullet shields are indicated by the color yellow and spirit shields are indicated by the color purple.

The alternate health bar can be enabled with the console command citadel_unit_status_use_new true. The command can be added with a + to the game launch options on Steam to be enabled on startup.

Sources

All vitality items implicitly provide base health based on tier, represented as "Shop Bonuses" in the ingame stats calculation. Tier 1 items provide +11%, Tier 2 items provide +14%, Tier 3 items provide +17%, and Tier 4 items provide +20%. The following items explicitly grant increased bonus health:
