Health Percent Damage, or just Percent Damage, is a special category of Spell Damage that resembles other MOBAs' 'True' or 'Pure' damage type. Abilities and Talents that deal damage based on a percentage of the target's maximum, current or missing Health do Percent Damage.

Percent Damage is flagged to ignore damage modifiers entirely. This means that percentage-based effects will deal the raw amount of damage regardless of the amount of damage Buffs or Debuffs on the attacker or the Armor state of the target. Effects that completly prevent or absorb damage, such as Protected status or Shields, however, are still able to mitigate Percent Damage.

Being classified as Spell Damage, it still interacts with associated effects, such as Arthas's "Anti-Magic Shell", Blaze's "Juggernaut Plating" or Spell Lifesteal. Percent damage instances do not, however, consume charges of Spell Block.

Percent Damage is capped to 36.51 damage per percent of Health for an instance of damage, Scaling by 4% per attacker's level. The cap is set to limit Percent Damage's effectiveness against high-HP Battleground Objectives such as Vehicles or the Immortals on Battlefield of Eternity. There are Heroes who can hit this limit in some cases, but in a normal game situation it is usually high enough to not affect Heroes of roughly the same level.
