with these buffs my dmg should be 86 ~ 87 but i did only 51 ~ 52 dmg… what the fck is going on here ?
It seems only concentrate is applying. Either way, this creature seems to have plate-type defense, so slashing it reduces your final damage by a fair amount. Concentrate usually applies after reductions, so it ignores those changes.
Everything is ok.
Gung-ho increase your basic atack - let’s name it status from 24-23 to 52-51 (28 ponits difference BUT this take Stone Whale Defence in calculation)
Concentration is additional unavoidable dmg on hit - that gold information
so You hit that boss for: 52(basic atack) + 33 (Concentrate additional DMG) = 85 dmg per hit.
I think concentrate does increment the number though.
Slash vs plate
both bonuses get diminished due to your weapon type, strike weapons will make gung ho/conc both add 50% more damage on plate armor
so everything is working as intended.
