This build will get the enemy really pissed at how quickly you kill them and heal so fast

these runes are must haves so you can obtain your passives at the start of the game

is picked for catching you enemies, running from ganks or getting to ganks of your own

] is picked to keep enemies where they are so they cant run away whilst you kill them

[Q] is great for harassment and surprise burst, this will be your bread and butter

[W] is your escaping or surprise attack ability, use this if you are ganked and just pick off the enemy without taking damage, remember, you have to right click on the enemy to attack them, it isn't auto, and when you attack you become visible

[E] is your AoE, you will use this in team fights and inside your shroud, it is also great for farming minion kills

[R] is probably the best ganking ability in the game, other then [Nocturne]'s ult, use this for diving in, then [W], [Q], AA, [E], [Q] and if there still alive and getting away, use [R] to finish them or chase them

I usually start with so i can get to the lane faster than the other champs and get the drop on the enemies, i also grab 3 for laning for longer for precious experience and gold. I then get a starting with the for the AP, and the passive is just amazing. i then get a for all the spell vamp and lifesteal, starting with the for the extra spell vamp earlier. i then get a for the ability power and spell vamp it gives to your allies and yourself. After that a is a MUST have simply for the amount of damage you will be doing with both your passives in effect. And to finish my build i grab a for the slow and the AP, but you can swap it for a for the extra health and slow if you are too squishy or they get way too much

Pros: epic ganking and laning abilty
super heals
YOUR A FLIPPIN' NINJA

Cons: squishy as ****
horrible 1v3-5 unless you can time your attacks and shroud
