Work out critical hit chance instantly with clear inputs, formula shown and shareable results.
Critical chances from different sources add before being capped at 100%, and across independent attacks the chance of at least one crit is one minus the miss rate to the power of attacks. A 35% crit chance almost certainly produces a crit over ten attacks, which is why crit-dependent builds get more reliable the longer the fight lasts.
Total chance
total = base chance + bonus chance, capped at 100%
At least one crit
P = 1 - (1 - total chance) ^ attacks
total = base chance + bonus chance, capped at 100%. Critical chances from different sources add before being capped at 100%, and across independent attacks the chance of at least one crit is one minus the miss rate to the power of attacks.
A 35% crit chance almost certainly produces a crit over ten attacks, which is why crit-dependent builds get more reliable the longer the fight lasts.
Enter base critical chance, bonus critical chance from gear, attacks in the rotation. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
