Critical Chance Strike ?

[grakky2]

I know the explanation in-game says it is for hits with skills that do not have specific modifiers but what's an example of this like which skill with what weapon or spell? What skill has no modifier?

Let me explain how it works for you.
Everything but DOTs (all skills with DOT tag and the DOT status effects) can hit and therefore can Crit.
You have a base crit chance of 5%. Then theres added crit strike chance that added to this base crit chance and then is multiplied by increased crit strike chance.
Then there's crit strike multipliers that increase damage of critical strikes.

Note some crit strike mod are spell or melee only while others are global.
