And i dont have any expectations to end it. U can search here (on mobafire or other sites) for much better guides, containing many more information.
Also, english isnt my native language and im not fluent in it, so i really dont give a f*ck to the grammar errors.
Read the other guides xD

Give you AD, some armor (helps u to be less squishy) and a sweet amount of life steal, which makes your laning, pushing or whatever u are doing easier in early-mid game.
The point here is: dragon and baron dominating. Wriggles will make it a breeze with his passive and life steal, and his active is very useful if u do it right.



For 1425 gold, you have:
30 AD.
240 HP.
9% life steal.
Want something more useful in early game? Nop



I thought it was a f*cking dumbness have 2 phantons in ad carries, but then i tried it one time and now... I just cant stop doing it, wtf

110% ASPD
60% crit
30% movspeed

Why dont take a IE? Or a BT?
Taking a IE, u would have 55% critical chance. Its very good, but not guaranteed to be a critical. It give u 80 AD, whats very good.
But IE is more expensive and dont give u movespeed; 2 phantom dancers + your passive makes u the LoL Usain Bolt.
IE dont give u attack speed, what is very very good in MF (W passive too gud).
And yeah, PD have even more crit chance than IE.
BT is nicely viable, but not now.
However, guides arent made to make u follow strictly the build given. Change whatever u like or dislike in the order, the game and chars (not forgeting the fun, of course) is yours.



QSS isnt a must. Survivability depends on the enemy team's composition and the situation, of course. Among so many items, I can mention:
Guardian Angel, if u end the game quickly and be more aggresive.
QSS, if u need the awesome active to counter a heavy cc team.
Last whisper if the enemies are building heavy armor.

And thats all. Have a nice game xD
