Hello. I'm a challenger ADC/Mid main on the NA Server (http://na.op.gg/summoner/userName=XxCorexX) and I found an abuse bug that you can perform on Graves. Read the guide for more insight.
Alright, now let's dive into the core gameplay that this build revolves around. For some reason, on patch 5.15, Graves's smokescreen is doing an extra 10 (5+5) base damage per level. For this reason, you need to focus on maxing it out as soon as possible. With this ninja buff/extreme bug, smokescreen does 5.2x more damage than a fully hit buckshot (all 3 pellets), meaning we simply don't need Buckshot during lane phase. Since Smokescreen scales with AP (Ability Powder) we will focus on that, along with cooldown reduction for 100% uptime.
