Percentage gets applied first then flat armor pen. Youmuu's Ghostblade & Duskblade of Draktharr are flat armor penetration while Last Whisper ( Lord Dominik's Regards ) is % percentage armor penetration. I will explain how to use it, what to build, and when you should use it. This build still works well, but is not as powerful or reliable as it used to be. It was the first Jhin build to be popular and it made Jhin broken for the first season he was released. The Lethality build is by far my favorite build. Next items will be situational items from this point on. You can also replace Statikk Shiv with Phantom Dancer if you want more protection and less aggression/damage. So, in a grouped up teamfight it can be devastating for the enemy team. It will also apply the Stormrazor slow and the total magic damage up to 7 targets.

The FOURth and finally part of the Crit build will be Statikk Shiv, it will add another 120 magic damage to the energized combo as well as bouncing up to 7 targets. So, the build is coming together well and amplifying each other's strengths.

The energized magic damage from Rapid Firecannon (120) and Stormrazor (120) also stack for a total of 240. The third item in this build will be Stormrazor, it's energized attacks provide a slow by 75% for. However, a Jhin with 600 AD + 4th shot Whisper ready to be used is a huge amount of pressure for a Rapid Firecannon and can be used to exterminate any target that dares get in your range. Think about a Twitch with 200 AD and Rapid Firecannon, it's not that important that he gets his 200 AD auto. It will give you 150 range which is big for Jhin. After you get Infinity Edge you'll be taking Rapid Fire Cannon. He will do 168.75% Critical damage with the I.E Passive. Since Jhin's penalty allows his Crits to do 150% Critical damage instead of 200% compared to normal ADCs. It provides 80 AD + 25% Crit chance which are both a massive boost to your AD stats. Instead, you will be buying Infinity Edge as your first item. A lot of people are still rushing Stormrazor however, it has been nerfed and it is no longer the first item. Crit has gone through multiple changes at the start of season 10 and pre-season.
