Doubleshot

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.

Using Manyshot and Ten Thousand Stars feats reduces your doubleshot chances by 100% for a time, effectively negating its effect.

''Some descriptions say that repeating crossbows receive a reduced benefit from Doubleshot but testing seems to refute the claim of reduced effectiveness with repeaters as of March 7, 2014. (See the talk page.)''
