Predecessor Builds > Sparrow > Gatling

This build leans into Sparrow's already amped speed of attack capabilities. Just make her shoot fast constantly. When you're staring down multiple foes, pop her Ult and her speed boost and lay waste. These items all have on basic attack or every fourth basic attack or next physical damage instance so that all feeds into the faster you shoot the faster they die motif. You choose the Pacifier crest for two reasons. To get a big hit when diving into a fight or finishing one if a target turns to run. Don't be afraid to pop it and then long shot them in the back for the kill.
