User blog comment:Demagonz/How do you know when to attack for the highest spark?/@comment-26407503-20160515174259

You need to go through trial and error because thats how your going to find out if your dual Rize/ Eze, Avant can perfect spark for example. It also depends on your device because some lag while others dont. If your interested in the perfect spark, just look around r/bravefrontier or ask in the help thread concerining about advanced auto battle and perfect sparking (because it is physically impossible for a human's hand to swipe faster than a machine)
