Explanation of the term

  • Effective hit points also known as EHP is a slang term used to describe how much damage your character can survive. The term hit points is a word for life and energy shield.

Math

  • Calculating your EHP
  • Add up all additive stats on your defensive layers first so that they are ready to be multiplied. Most additive stats come from increased and reduced, but there are exceptions to this rule.[1].
  • All of these defensive layers can be calculated with the same formula - Dodge, Block, Evade, Blind, resists, Less/reduced Damage from hits, Lower monster action speed (when facetanking), avoid, lower enemy accuracy, lower enemy damage, physical damage reduction and resistances.
  • Formula - Minus the % from the defensive layer from 100. Then divide 100 by the answer.

Example

  • 75% attack Block ( 100 - 75 = 25) (100 / 25 = 4)
    • 75% attack Block gives you 4 times EHP against attacks that hit.
    • All layers are multiplied separately as if they were "more" stats. This means a character with 4 times EHP would go to 8 times EHP by adding blind which is a 50% enemy chance to miss.

Advanced Math

This formula is not advanced on purpose to make it easy to understand. It does not cover all possible mechanics of defense.

See Receiving damage for more advanced formulas.
