Because Crit Chance rolls appear on so many slots (Gloves, Rings, Amulets, class off-stat, skills/passives), it is very easy to end up well past 100% without noticing, at which point every one of those points is contributing literally zero damage.
See brk_crit_chance_100_and_balance_formula for the full mechanic and the balance formula; this entry exists specifically to flag it as a trap because it happens by ACCIDENT (gear accumulation) far more often than by deliberate min-maxing choice.
Any Crit Chance total above 100% contributes 0 additional damage.
Periodically audit your character sheet's total Crit Chance; if it's meaningfully above 100%, reroll/retemper the excess into Critical Strike Damage for a guaranteed upgrade.
