Critical Hit Chance - Am I reading this wrong?

I was experimenting with a critical hit build with the Mercenary, and some support gems are a bit confusing.

There are two different wordings when it comes to support gems that affect critical hit chance:

- "Gain #% increased critical hit chance" (ex: Inevitable Critical)
- "Have #% more/less critical hit chance" (ex: Excise)

My understanding was that the first wording is a multiplier applied to the base crit chance, whereas the second means a flat percentage added to the total. For instance, considering a 5% base crit chance with a crossbow, a "gain 10% increased critical hit chance" would bring the total crit chance to 5,5%, but a "have 10% more critical hit chance" would make it so the final crit chance was 15%.

However, in-game it seems both effects work the same, simply as multipliers to the base crit chance.

Is this intentional, or am I simply misunderstanding the way critical hit chance works? If so, maybe an adjustment in wording for these critical hit support gems could help clarifying the issue.

I could also be misunderstanding, but if you look at the node "Struck Through" on the ranger tree it says "Attacks have a +1% chance to critical hit chance" and this indeed increases the flat base of crit chance.

I believe that the "more" keyword basically is a secondary multiplier applied after the additive multiplier.

base_chance * additive_multiplier * more_chance_1 * more_chance_2... etc for each "more" you have.

so in the case of 5% chance, 10% increased, and 10% more I expect it to be

5% * 1.10 * 1.10 = 6.05% chance

I might be wrong!!

You are correct, a flat increase will have something like "+X% Chance to Crit", with the + sign being key. % increase is a multiplier of your total base crit, and is additive with other sources of % increase.

% More mods are each their own multiplier. They are only additive within their own source. (IE. If skill says it gets 100% More damage for each power charge spent, the power charge's 100% are additive with each other, but multiplicative with all other mods)

Ah, I see. The word "more" threw me for a loop there.

Thanks for the explanations!

the explanations are correct, and this wording is universal in the game, the words "increased/reduced" and "more/less" are used very deliberately and always tell you how a stat interacts with your character.


all sources of "increased/reduced" are added together and then applied. sources of "more/less" are applied separately from each other and sources of increased/reduced.


30% more of something will always take the value you currently have and give you 30% more of it.



this wording will be consistent for everything, armour, crit, damage, life, any stat youll see this wording.
