Damage Calculator

Model your effective damage per hit: weapon attack scaled by your damage increase, the PvP/PvE multiplier and expected crit, then cut by the target's damage reduction. Autofill from any weapon and any monster.

Monster autofill sets Health and Defence. Damage Reduction is the target's physical resistance — sum it from a player's armor or leave at 0 for an unarmored target.

About this model

This is an illustrative model, not the game's exact engine. It composes the documented combat stats: Attack × (1 + Increase) × (1 + Mode increase) × (1 + crit EV) × (1 − Reduction). The game keeps the flat-Defence-to-mitigation curve and its weapon / monster coefficients private, so we don't fold flat Defence into the number — we show it after penetration instead (more penetration is always better). Item attack values also exclude your character's base stats, talents and affix rolls, so treat the per-hit figure and hits-to-down as a relative comparison between setups, not a literal in-game number. See the Combat & Attributes guide for the full damage model.
