Health

Health, shortened to HP, is a statistic that determines the amount of hit-points a unit has before When a unit hits zero health, the unit dies. Health can be restored by health regeneration, healing, physical vamp, and magical vamp.

Health is represented in-game above the champion. Each small bar represents 100 health. Due to size constraints, current health can only be seen at the third tab of the scoreboard. Damage directly reduces a unit's current health. Maximum health is reduced by debuffs and increased by abilities, items, and runes.

Every unit and structure has their health displayed as a bar above their models.
 * Wards and similar champion summoned units have segmented health bars that each represent one life, but require another attack to remove.
 * Minions have a small non-descriptive bar.
 * Champions show a gauge on the health bar that illustrates the amount of health.
 * Large monsters and Epic monsters, as well as structures display an exact health count along with a non-descriptive bar.
 * On Wild Rift, outer turrets have a gauge that represent plating.

Every champion starts with a certain amount of health, called base health. This increases by a small amount each time the champion levels up.

Health also stacks additively, with each bonus point directly affecting it.

Effective health
Effective burst health, shortened to effective health describes the amount of raw burst damage a champion can receive before dying in such a short time span that they remain unaffected by any form of health restoration.

Assuming that health is, armor is  , and magic resistance is  , the following shows effective health formulae:


 * $$\text{Physical effective health} = h(1+0.01a)$$
 * $$\text{Magical effective health} = h(1+0.01m)$$

Physical effective health and magical effective health are effective against physical damage and magic damage, respectively. They correspond to the amount of damage that an enemy champion must output to bring your health to zero.

An example is the following: If you have 1000 health, then purchasing 90 armor will raise your physical effective health to 1900. Enemies will have to output 90% more physical damage than usual to kill you.

Gray health
Gray health indicates the portion of damage that was recently taken, stored on the health bar. It is designated for certain champions' abilities. Effects based on health do not account for grey health.

Champions with grey health:

Gray health appears dark gray on the health bar and between current health and any active shields.
