Are Crit Chance Mods Additive Or Multiplicative?

[krisp]

I remember they were multiplicative before update 7 but back then you had passives that made crit mods worthwhile.

So now that they changed everyhing, is that 45% (on a maxed rifle mod) of the maximum crit chance, or 45% of the base percentage?

Because if it's the latter then crit mods are the most useless things in the entire universe and I should avoid them like the plague except if I'm meleeing as Loki or Ash.

Right now it seems like the latter is true, I don't exactly crit 1 out of 2 times. Can anyone confirm with a good source?

Multiplicative, of course. Based on using 45% crit mod on my Braton, and getting 2-3 crits per mag.

The way crit mods work right now makes them absolutely useless. There are many other threads about it but until now the Devs did not respond to it.

45% on maximum or on base is the same thing without tree you know.... this is why every1 wants back the freaking skill tree, whatever % the mods add now dont include any of the nodes we used to have that are multiplicative so , the amount 45% is actually lesser than how much it is in pre-update 7

By maximum I meant 100%.

well, that can be tested easily if u run around attacking 2 times and 1 of them is crit most of the times, i havent tested this after patch 7 so i cant tell for sure, but anyhow i can guarantee the chance is a whole lot lesser, and i believe its not 45% of 100% now. because they are trying to nerf us, do u think u can get 45% crit really? lol look at the other mods and you know it really isnt going to happen. and btw that weapon should have a base crit itself, so with a 45% mod, if it works on a 100% basis, than u should have above 50% crit rate giving u at least 1 crit every 2 hits.

[krisp]

Yeah it really seems like a bug atm. Crit mods are absolutely worthless.

do u think u can get 45% crit really? lol look at the other mods and you know it really isnt going to happen.

They wouldn't be all that powerful even if it was additive. 45% chance on average means 22.5% dps increase which doesn't hold a candle to Serration's 100% (or 60% at the same rank as crit chance). You need to use crit damage in tandem in which case you've just wasted another mod slot to make the 45% be worthwhile.

It really is a laughable situation.

So if it's based on % , isnt it essentially the same as a multishot?

Absolutely not.

Multishot increases all your damage output by a %. Crit chance only increases the amount of extra damage you get from crits by a %. Extra damage from crits is usually around 2.4% of your total damage output.

Average damage output is

Base Damage x Damage Multiplier x Multishot Multiplier x (all elemental damages added together multiplier) x (1 + Base Crit Chance x Crit Chance Multiplier x (Base Crit Damage x Crit Damage Multiplier - 1))

A pretty common base crit chance right now is only 5%. I don't know about now, but before update 7 the base crit damage for most weapons was 1.5x. So, with just a crit chance mod, your crit damage is looking like 0.05 x 0.5 x crit chance or 0.025 x crit chance. So, your total damage output is (damage modifiers) x (1 + 0.025 x crit chance). A 45% crit chance mod puts it at 1 + 0.03625, so your damage increases by slightly above 1%.

Throw a 60% crit damage mod on there, too, and your damage is 1 + 0.05 x 1.45 x (1.5 x 1.6 - 1) = 1 + 0.1015, which is a total increase for two mod slots and 18 drain of ~7.5%.

Wow ur kidding me....a 45% crit chance only increases damage by one percent??! So it's not 45% chance to do double damage or it's nothing like a multishot? Why is it so low?

You have the math. A weapon has 5% crit chance, increasing that by 45% means 7.5% total. The 2.5% crit means 1.25% damage increase because crits are 1.5x damage.

all these just say 1 thing, the crit and crit damage mods are right now summarised in 1 word "joke", uncomparable, totally off-scale of what we had in the past, not to mention it over consumes the mod capacity which is already extremely limited.
