Twitch was one of the worst junglers in s10, imo it really changed in s11 mainly because of smite changes.

Your clear is really hard early, red now has 20 armor on start and all jungle monsters are faster so it's harder to kite.

In most of low elo games you want to do RED into any lane gank. If you get first blood you will have big advantage that you don't want to waste. After gank you want to get your blue into Gromp Gromp now gives a lot of hp and mana. After that you want to gank another lane or do crabYour crab clear is way easier thanks to s11 change: His armor shield drops after destroying his shield.

When you are ganking you want to make sure that you use your Q Ambush before any ward can see you,lane ganks are also very powerfull just use your Q Ambush behind your turret.

PTA

Press the Attack - Use in most situations, very high kill potential on ganks, also strong late

Conq

Conqueror - Much more viabla in s11 thanks to dmg on stacks buff, amazing in teamfights with twitch R Spray and Pray, way worse kill potential than pta.

Hob

Hail of Blades - Really strong early and in late vs squishy targets mainly viable cause of ap twitch being turbo strong right now.

Lethal Tempo

Lethal Tempo - Low kill potential, very bad early game, much better late but conq is still better. Only way it can be better than other runes is when you have lulu.

Immortal Shieldbow

Immortal Shieldbow - Best item you can build, his stats gives everything that twich needs early + his passive makes u pretty much invincible

Kraken Slayer

Kraken Slayer - Really good vs tanks, works well with attack speed overall DPS is better than Immortal shieldbow but you need to live to do dmg

Duskblade

Duskblade of Draktharr - Not playable anymore due to 10.25 nerfs eclipse should be better now.

Eclipse

Eclipse - Much better than duskblade, but also got nerfed in 10.25 it's way worse on ranged now.

Nashor's Tooth

Nashor's Tooth - Best item to buy on AP twitch amazing stats and passive, works well with rabadon 2nd item.

Runaan's Hurricane

Runaan's Hurricane - Still item that has the best synergy with twitch. Thank's to new season changes it's even better, now it gives you more attackspeed and attack damage. Additional attacks are stacking twitch passive on enemies, also in teamfights you will notice that it deals huge damage to squishy targets.

Infinity Edge

Infinity Edge - It's not as good as before, it scales really long but in the late game it becomes really strong. If you don't know how it works now I will explain:(After 10.25 changes it scales faster but is a little bit worse) You start with 175% After 60% crit chance Infinity Edge passive gives you 35% crit damage, so maximum crit damage is 210%, we are aiming for that.
