Hey Prestonia again, this is my favorite build for twitch, I've had good stats as well KDR with this build. 75% Crit chance, good attack speed and on occasion 1005 crit attacks. But with this build it'll get you a foot in the door with Twitch. Near end game with your ult your able to 4 shot or 5 shot other champs with your auto attacks.

With Twitch you get to use his pokey style to your advantage, don't waste your E until they are running or they have full stacks of Deadly Poison. E will help you get that killsteal or make sure your enemies don't get away. You can also use W first to slow them so you can get that full stack first. And Q is one of my favorites because it helps you get away from enemies if you use it with W's slow or you can use it to power play an opponent by using surprise attacks and when leaving stealth you are given a hefty attack speed buff that lasts for a few seconds. So once you get a hang of his abilities you'll be raking in the kills.

When first starting out getting the Brawlers Gloves help's you get your creep score and also helps in early game fights. Than when fully building it into the Stattik Shiv you get to use the passive to farm your lane faster/easier and gives you a good attack speed and Critical Strike Chance. Than starting out into buying the Bloodthirster helps you keep your sustain while in fights/laning. Than going on to build your critical strike chance and your attack speed helps you get a steady damage output. I suggest the first two items are built in order and the following can go in whatever order you please.
