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.

Starting Health

Kelvin's Starting Health, at 600 HP and 0

Starting Health is an amount of health that a specific hero is spawned with at the beginning of the match. It is a predefined amount that remains constant within a match, and differs between heroes. It must not be confused with Base Health, which can change throughout the match.

Base Health

Kelvin's Base Health at 20.0k

Base Health includes your starting health plus health gained through power increases. Once Base Health is increased, it cannot be given away, it is a permanent stat increase that will affect and modify multiplicative bonus health buffs and debuffs.

Base HP can be calculated using this formula:

$BaseHP=StartingHP+\overbrace {Level*PowerIncrease} ^{Power-Increase-HP}$

Bonus Health

Bonus health can be obtained through Items, Gold Urns, and Survival power-ups.

There are two types of bonus health: additive, and multiplicative

Additive Bonus Health

Additive Bonus Health refers to any bonus health that is stacked over the hero's Base Health. It does not alter any other health status that requires multiplication such as vitality items' bonus health.

An example of this would be:

$TotalHP=BaseHP+\overbrace {20HP} ^{Gold-urn-buff}+\overbrace {400HP} ^{Survival-Power-Buff}$

Gold Urn Health

Gold urns Additive Bonus Health. Notice how after the 15 minute mark the healing goes from +15 HP to +20 HP

Gold Urns will begin to spawn after 3 minutes has elapsed in the match. When destroyed, they have a 50% chance to drop a small stat buff. All buffs obtained are permanent when picked up. The urn will respawn 3 minutes after being broken.


Time Elapsed	Bonus	Chance of getting health bonus
0-3 minutes	non existant	0%
3-15 minutes	+15 HP	8,4%
15+ minutes	+20 HP	8,4%

Because of their additive nature, Golden Urn buffs don't alter a hero's base health, but instead stack over it.

Survival Power-Up Health

Survival power-up timer

Power-ups spawn after the 10 minute mark and subsequently after 5 minutes intervals. There's a 1/4 chance of the Survival power-up spawning in one of the two off-lane bridges.

The Survival power-up will grant you an additive +400 HP Bonus Health on pickup, and a multiplicative 1% health regeneration

The effect will last a total of 160 seconds. Picking more than one Survival power-up will reset the timer, meaning that you cannot stack multiple instances of it.

Because of their additive nature, Survival power-ups don't alter a hero's base health, but instead stack over it.

Multiplicative Bonus Health

Multiplicative Bonus Health refers to any bonus health that works by multiplying a hero's base health, meaning that it takes into consideration both the hero's Starting Health plus their Power Increase's Health

An example of this would be:

$TotalHealth=\underbrace {StartingHP+\overbrace {(1level*50hp/level)} ^{Powe-Increase-HP}} _{BaseHP}+\overbrace {(BaseHP*0.11)+160HP} ^{extra-health}+\overbrace {(BaseHP*0.11)} ^{extra-stamina}$

Multiplicative Bonus Health is calculated based on your current Base Health. This kind of bonus health will increase until you get to your 14th power increase, where you will no longer be able to increase your base health.

Vitality Items Bonus Health

Vitality Items have an intrinsic multiplicative bonus health buff that increases according to item's tier. It can be seen in the top-right quadrant of each item's description. The Vitality Item Intrinsic bonus health is independent from the additive bonus health of the item itself, and only applies to the hero's base health:

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

Math

The formula for max health $HP_{Max}$ is:

$HP_{Max}=\left(HP_{0}+N_{PI}\times PI_{HP}\right)\times (1+\textstyle \sum HP_{Shop})+\textstyle \sum HP_{Bonus}$

where $HP_{0}$ is hero-specific starting health, $N_{PI}$ is the number of Power Increases earned, $PI_{HP}$ is hero-specific added base health from each power increase, $HP_{Shop}$ are the implicit base health percent increases from Vitality items, and $HP_{Bonus}$ are the miscellaneous bonus health flat increases from items, Golden Statues, Survival Powerups, the Rejuvenator, etc.

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

Note that the max health presented in-game is rounded to the nearest integer.

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:

$HP_{Max}=600\times (1+(0.11+0.11))+160=892$

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

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

Health Bars

Health Bars are visual indicators of a hero's current health, located just above each hero. Health bars consist of filled orange squares of equal width, arranged in rows of up to ten squares. Each square represents 100 health, and each full row represents 1000 health.
