His max movement speed is faster then what it says here 9.5% from runes and masters will make you faster aka more damage

Pros-
1: Awsome late game
2: Can kill great late game using his passive and PD's
3: repeating 1 and 2...
4: Good Soloer on top(example: Master Yi attacks you at the turret you use exhaust to slow him while being attacked by you and the turret)

Cons-
1: Squishy early game
2: Has trouble doing damage until level 3

I suggest Ghost to make his passive do more damage which is my whole point of my build which It works with the critical chance and extra damage.

Exhaust Just slows them for other people to kill them while your just doing ur damage healing using "W"

Always let your team go in first then just attack them they most likely will target you so charge in and have your "W" and "E" on

I've been repeating myself but most of his builds that people give dont use his passive...So get speed...

P.D gives 15% which is some extra damage plus critical chance plus attackspeed... which makes this build OP

Trinity gives extra damage after using a spell so you want to have it to do more damage.

Speed is my runes
plus the armor pen'
And some armor because he needs it to make him survive battles longer
Magic reist incase feeders apear late game

I spam myself... Just get Movement speed most people dont use his passive and you need to go in second - last because you dont want to die because you most likely do the most damage
