one does not simply build IE last as an ADC. rageblade is kinda useless, if you want AS get a phantom dancer

The runes.... two of those sets are F-tier runes. Please go here

You're sacrificing so much potential durability for so little extra damage. Sheen or no sheen high sustain supports and kill lanes will both wreck this so hard.

Im sorry but your build and runes are way off you should really use Greater Seal of Armor and Greater Glyph of Magic Resist BECAUSE most of the time your support will suck and twitch is really squishy and could die to one burst also he can trade off,
next is your build im sorry but twitch does not need a Trinity Force he has a built in slow and he kind of has a escape, he does not need a Guinsoo's Rageblade. lastly i would rather take a Phantom Dancer then Trinity Force overall movement speed + crit is great.



edit i looked at your runes i see that you get 16 flat ad at lv 1 if you got flat and marks and quints you can get 15 flat ad also you could get Greater Seal of Armor and Greater Glyph of Magic Resist for living longer

This guide is so bad!

1. Never go for flat AD everything, Greater Seal of Attack Damage is just bullsh*t.

2. Like Oscardogg100 said, use BBCoding such as the examples below.
3. Work on your information more, it lacks too much information, I hardly got to know Twitch at all.

I'm sorry but DOWNVOTED!

Needs Pictures and Videos. Plus needs BBcoding like Infinity Edge!! Check out jhoijhoi's Guide on how to make a Guide!! :D (In the Builds & Guides Section)
