Doublestrike

Doublestrike
Doublestrike grants a character a chance to make an additional attack roll 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.

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