Critical damage [formula]

Hey guys, i’m trying to understand the crit dmg formula, the crit chance i got it already.

for exemple, ignoring all defenses and stuff, if i hit 3k with normal skill with 0 crit dmg, i’ll crit 4.5 cuz the crit itz 1,5xad right?

but if i add crit attack into it? if i do the same formula, but with 100 crit attack, i’ll hit 4.6?

if this is it, crit dmg sux hard.

and btw, critical ignores defense?

thanks.

it doesnt

My understanding is that you’ll hit (3000+100)*1.5=4650

i see, if is this the case, crit dmg really sux before late game lol.

Nope it just depends on how much you care about upgrading your weapon.

can elaborate it better please?

well most of the formula is flat so the more upgrades you put in and the better the weapon the more base value you have before the multiplayer. so after the multiplier you would obviously have even more. Alot of players don’t upgrade their weapons which is a big mistake especially for archers with the missile damage modifiers.

The critical damage part ignores defense. The rest does not, so you get your damage, and multiply it and such, reduced by whatever it needs to be reduced by, then add the critical damage as “true damage”.

Have you ever actually tested if critical attack ignores defense?

I’ve never personally been so weak that 1.5x damage doesn’t put my attack over the target’s defense.

It doesnt ignore defense.

anyone knows the current formula for the crit damage output? how can i calculate it?

The newest formula made a drastic improvement to how Crit Attack interacts with modifiers.

The new formula is (PhysAtk + CritAtk) * SkillMod (* 1.5 still?) I believe. Whereas Crit Attack used to be a flat addition at the end of the damage calculations, it is now calculated into skill modifiers. Even if the 1.5 multiplier was removed, which I haven’t yet tested, this still makes for a rather nice boost in damage as someone with 1000 Crit Attack (obtainable endgame and with a DEX build) being multiplied by, say, a 1500% skill is another 15k damage on top of your physical attack’s contributions.

As far as i know, and the idea i get from the Grand Multiplier thread. Crit attack is added to the skill mod, but not timed with 1.5 on crit. Also crit attack gets screwed by the log algorithm because catk isnt added to the defense calculation.

The full formula on crit is something like this: Damage = ((skillFactor%) * ((Patk * 150%) + Critical Attack)) * min {1, log10 ((Patk / (Pdef + 1))^0.9 + 1)} + Additional Damage

Therefore since critattack doesnt get added into the log scale, and doesnt get timed by 150% on crit, if you have equal patk and catk, patk is superior. However catk is easier to stack
