Doublestrike

Doublestrike grants a character a chance to make an additional attack with their main hand weapon any time they make a main hand melee attack. The additional roll is made on the target of the initial attack. Doublestrike only applies to melee attacks. (Similar effect for ranged attacks is called Doubleshot.)

Doublestrike was introduced as part of the Update 5 combat changes. Many attack speed bonuses were converted to Doublestrike effects at that time.


 * Doublestrike affects your main-hand weapons. See below for information about off-hand doublestrike.
 * Increasing Doublestrike above 100% does not provide any additional benefit.

Since Update 45, many Cleave attacks can now doublestrike.
