Critical Range Boost increase less damage than the description. I have it at level 2 which should increase the damage output by 15% but it was only around 6%. Please see the attached images.

Hi @SANDHOOF, are you familiar with the damage formula?

If you are, the CRB damage buff goes into the same bucket as the rest of the “Increase damage by x%” types of buff, such as Reckless, Normal Ammo Boost, and Fighting Spirit.

Based on the build you’ve shown and the damage numbers,

10.5 Diablos HBG at level 5 customisation = 2422
Attack Boost 2 = +100 flat to Attack Power
Reckless 3 = +20% damage
Normal Ammo Boost 2 = +120% damage to your normal ammo
Fighting Spirit = +10% damage

Training dummy HZV is 130%.
Normal Ammo MV is 26%.

Ommitting the missing variables from your build and simplifying some parts of the formula:
Wpn_AtkPwr * HZV * MV * (1 + sum_dmg%_buff)
(2422 + 100) * 1.3 * 0.26 * (1 + 0.2 + 1.2 + 0.1) = 2522 * 0.338 * 2.5 = 2131.09, rounded up to 2132
This is your damage on the left side of the screenshot

Critical Range Boost 2 = +15% damage
↓
(2422 + 100) * 1.3 * 0.26 * (1 + 0.2 + 1.2 + 0.1 + 0.15) = 2522 * 0.338 * 2.65 = 2258.9554, rounded up to 2259

Since your actual damage is 2262, I guess that your CRB driftsmelts had up to a total of +3 Attack Power in their sub-stats, which results in
(2422 + 100 + 3) * 1.3 * 0.26 * (1 + 0.2 + 1.2 + 0.1 + 0.15) = 2525 * 0.338 * 2.65 = 2261.6425, rounded up to 2262

Thank you! Now it’s clear to me.
