How to use it
Take the base damage from the skill or weapon tooltip (for attacks, the weapon's damage range of the type you are scaling; for spells, the gem's damage at its level). Put flat damage from gear, tree and auras into the "added" fields; it is added before any multiplier. Add up every "increased" and "reduced" modifier that applies to the hit into one number. Each "more" or "less" goes into the multipliers field separately, for example support gems, "more damage with hits" on the tree, or a 40% less multiplier from a skill.
Critical hit chance is the weapon's or spell's base chance plus flat bonuses, scaled by increased crit chance and capped at 100%. The critical damage bonus starts at 100% in Path of Exile 2 and each "+% to Critical Damage Bonus" adds to it. The average hit weighs normal and critical hits by their chance.
For elemental and chaos hits the enemy's resistance, lowered by exposure and curses and then by penetration (which stops at 0%), scales the damage taken; for physical hits armour reduces each hit depending on how large it is, so crits lose a smaller share. Formula details and version notes are on the how it's calculated page.
FAQ
What is the difference between "increased" and "more"?
All "increased" and "reduced" modifiers are added together first and applied once. Each "more" or "less" modifier is a separate multiplier. 100% increased + 50% more = ×2 × ×1.5 = ×3, not ×2.5. Enter the sum of increased in one field and every "more" separately in the second.
How big is a critical hit in Path of Exile 2?
A critical hit deals the hit multiplied by (1 + critical damage bonus). The base critical damage bonus is +100%, so a crit with no bonus deals double damage; "+40% to Critical Damage Bonus" makes it ×2.4. This is different from the first game, where the base was 150%.
How do penetration and exposure interact with resistance?
Exposure and curses lower the enemy's resistance first and can push it below zero, which makes the enemy take more than full damage. Penetration is applied after that and cannot take resistance below 0%: any excess is wasted. Exposure applies only to the element it names (−20% by default, weaker on magic, rare and unique monsters).
Does this calculator include accuracy, ailments or damage over time?
No. It computes the damage of a single hit that lands. Chance to hit, bleeding, ignite, poison and other damage over time are not part of a hit's damage.
