Prefix  ☣ 
Crit Chance is one of the Combat Stats. It indicates the odds of landing a critical hit, which will add Crit Damage into the Damage Equation increasing the final damage dealt by the player significantly.
Calculation
For example, if the player has +100% Crit Damage and usually deals ✧10,000 damage to a mob on a noncritical hit, then when a critical hit lands the Crit Damage multiplier will be added to the Damage Equation:

and the damage will be multiplied by x2 times! This will make the final damage to show up in white, yellow, orange and red (✧20000)
Main Article: Damage Calculation
There is no actual reason to have more than +100% Crit Chance, unless the player wants to receive bigger bonus effects from enchantments like Overload.
