Doubleshot

Doubleshot grants a character a chance to make an additional attack roll with their ranged weapon any time they make a ranged attack. The additional roll is made on the target of the initial attack. Doubleshot only applies to ranged attacks.

Doubleshot was introduced as part of the Update 19 combat changes. Many attack speed bonuses were converted to Doubleshot effects at that time.

Update 28 Patch 1 changes:
 * Manyshot and Ten Thousand Stars no longer reduce your doubleshot chance.
 * Repeating crossbows now have 1/3rd the chance for Doubleshot.
 * Doubleshot can now "wrap" and cause a third or fourth shot if it goes above 100%.
