③ Attack Efficacy
L様※This corresponds to the red underlined section and is the "multiplicative calculation" applied to overall physical attack.
※Since it follows the same calculation as Elder Dragon-type effects applied to elemental values, it is considered a very powerful modifier.
Do not round down intermediate physical attack values. Add ② Attack Up and Drift Parameters, apply ③ Attack Efficacy, and round down only once at the end.

| Attack Efficacy | 10% | 15% | 25% | - | - |
Worked example: Attack Efficacy and final rounding
The following assumed values illustrate the MHNowCalc formula. They are not measurements or the performance of a specific equipment build.
Assume Weapon Attack 1,003, Style Boost Value 0, Attack Multiplier 30%, Attack Up 100, Drift Parameters 10, and Attack Efficacy 25%.
1,003 × 1.30 = 1,303.9. Keep the decimals and add 100 + 10 to obtain 1,413.9.
1,413.9 × 1.25 = 1,767.375 → round down once to physical attack 1,767.
Rounding 1,303.9 down prematurely would instead produce 1,766. Attack Efficacy multiplies the whole physical value, including Attack Up and Drift Parameters.
