Reminder when playing Twitch
When you leash your jungler, as people now tend to smite first for the jungle smite bonus, remember that there is always a possibility to steal the jungle monster with your passive. 3 damage per tick. It happened to me three times and I got early kills due to faster leveling but it caused the jungler to fall behind. (NOTE: This is a bad thing and jungler will hate you if that happens)
Max your E first. Get your E first. Your stealth don't do anything at level 1 unless they decide to counterjungle. If you get some autos in, you can hit the E to harass.
Know that Twitch has a rather bad laning phase. Save your Q and go into a bush, enter stealth and engage when support pretends they are simply aggroing. Unless you are facing high burst or tanky supports with hard lockdowns.
Reminder that YOU WILL draw turret aggro with your passive so don't turret dive as Twitch.Your ult outranges turret. Use that instead if you are confident you can kill them with one or two more auto.
If enemy doesn't have a pink ward and you have at least 3 ranks on Q, as soon as you hit stealth, walk to the enemy team and loop around them. Everyone expects you to go forward. No one suspects you to change direction all of the sudden.
Your ult doesn't work on Nexus. Don't use that when xpeke
