Hey guys, this is my guide for Twitch, I hope it helps and sry for my bad english.^^

Pros:
-great splash damage [+ aoe slow then]
-great pusher
-good for ambushing
-can watch out for oppenents in stealth

Cons:
-squishy
-often focused in clash
-can be seen with wards or oracle *

* Pro: oppenents need to spend money for you!


Summoner Spells:
With FLASH you can:
-get away from cc s
-getting an running oppenent
-flash over walls
With CLEANSE:
-you can cleanse cc in clashes to survive or spray some more



Spells you can also take:

With GHOST you can:
-get away from ganks
-getting an running enemy

With IGNITE you can:
-deal even more damage while ambushing a single target oppenent
-reduce heal

With EXHAUST you can:
-slow an enemy to kill him
-reduce the dmg of any single target to ensure your kill

I like ghost+flash and cleanse+flash most, but ignite and exhaust are also spells you should think about, especially if you try to get firstblood on my way.

Items:
You always start withdorans, then buyavarice blade 1-2 (I prefer 1 and berserker greaves.
Now you buy YOUR item, the item which totally let you rape, INFINITY EDGE!After Infinity Edge you normally buy phantom dancers,bloodthirster, youmus,sell dorans and get frozen mallet OR banshees veil.

If you need to (you often will) buy banshees veil earlier, you just need infinity edge and phantom dancers before that.

But there are additional items you can get, for example if your oppenents have much life (vladimir, garen...)or much cc.
In that case you can buy
Madreds Bloodrazor
Black Cleaver
Occults
starks (aura...but it do not matters in lategame)
last whisper (puh...after patch it is a bit difficult, but you can try it;) )

Before I start off with the guide... This is not a high elo guide, but it is not meant for the low elo hell, so you should have a jungling oppenent nearly every game.

Early:

YOU are the one getting firstblood.
Early.
At around 1:40 1:50 you are sneaking with stealth in the grass behind the golem.
[In this case you skill first stealth and then expunge]
You instantly attack the jungler after he finishes Golem, so he is low when you attack him.
With flash+ghost you should get him in 90% of all cases.
After that you go on your lane with your lanemate.
[You should not sololane or mid]
Maybe you need to train a bit, but then you need to do one thing all the time. LASTHITTING!!!
You should never play aggressive and you are not allowed to die in early game!

Midgame:

Watch out for oracle and wards.
If you already have much of infinity edge, you can gank, if not push lonely lanes and get away with stealth if someone is coming to defend.
Farm very well this way.
When you bought Infinity Edge, you can start picking up squishies at junglebuffs.
Plant wards if possible.

Now you need to win many clashes, soooo you need to get the feeling for the right positioning and attacking in the right moment, with spray and pray and a good team coordination+ tank [amumu+galio+shen are nice :)] you should easily win the clash ;)
You first use spray and pray, instantly w and then expunge to finish off the carry/supporter.

Lategame:

You got the equipment your oppenents got the money you want :D Get them!
You are raping, you got the power! ^^
For sure kills you get red buff as much as you can, steal it from enemy too!
Just keep on carrying your team to victory like in midgame.


First Blood at Jungler
You can Firstblood nearly everybody there.
I say nearly cause I did not met every jungler there, but actually I never failed it.
You can kill there every tank.
Amumu, Malphite, Rammus... Food.
You just need to flash after them.
Melees are easiest.
WW is soooo easy, you will laugh if you see him on the loading screen :D
(even with smite hes low enough to die against you)
Without Exhaust he do not have any chance to survive.
You do not even need to flash.
Tell me if you met someone, you could not kill there.
I would like to add Casters, but I never saw a Fiddle jungling while playing Twitch :(


I hope this guide is helping you to control twitch and have a lots of fun with him :) Give me tips what i could make better!
