Pick one base stat and see how much of each other stat gives the same damage.
How is it calculated?
Damage is three parts multiplied. Within each part, values add up.
- ATK efficiency = added % ÷ (100 + total ATK%)
- Amp efficiency = added % ÷ (100 + total amp)
- Crit efficiency = (crit rate × crit dmg gain) ÷ expected crit multiplier
The higher your total, the less each +1% is worth.
Damage Efficiency Calculator Guide
Damage is attack, crit, and amp multiplied together. Within each category, values add up.
The same +3% is less efficient when your total is higher — that is why current values matter.

Frequently Asked Questions
QDoes gear enhancement affect efficiency?
Not the ATK% damage efficiency. It only makes the real attack gain larger.
QWhy enter current attack?
It is used for the real attack gain and flat-ATK efficiency.
QWhy is ATK% efficiency low?
A high total makes each +1% a smaller share. That is expected.
QWhy no HP?
This tool is damage-only. It does not cover survivability.
