Critical Strike Damage

The Critical Strike Damage affects the amount of bonus damage that a champion's critical strike deals. All champions begin with +100% bonus damage on a critical strike. This statistic scales additively. Each bonus point acquired directly affects the statistic.

Critical hits are based on the champion's damage. Champion level and items affecting base damage therefore also raises overall critical strike damage.
