So crit chance is that flat number, like 250 and all the percentage boosts are based off that and are not a flat amount? So if I use Ako's ex skill its not adding a flat 39.5% crit chance, its increasing their base crit by that amount? if that's the case, I have Himari and Ako but since I'm new and all my gear is T4 at best would it be more useful to invest in Himari since I don't have any with good crit chance yet?
