4. take the skuttle closest to you and look to lanes for an early lvl 3 gank.
5. Wolfs

Buy pinks and pots (Do not be bronze) :)
Sweeping lenze is also helpful if teemo shrooms are really getting annoying! :)

PROS:

-Lots of early game damage and sustain.
-Easy To gank with and lots of snowballing potential
-Destroys Minion waves, Turrets and inhibs late game (amazing split pusher)

CONS

-Easily ShutDown with heavy CC
-Squishier then other Vi builds (However makes up for in damage and focus capability)

COMBO WITHOUT BELT:

1v1: Q,Auto,E,Auto,Auto,E,Ult
Ganking: Q,E,Auto,Ult,E (a lot of damage in a shorter amount of time)
Focusing: Ult,Q,E,auto,E ps: then zhonyas if you have it. pps: witch you should not as you should have protobelt before zhonyas.

COMBO WITH BELT:

GOD VI BUSH COMBO: Q,E,PROTOBELT,ULT,E
Focusing: Ult,Q,PROTOBELT,E,auto,E (zhonyas)
1v1: Q,auto,E,auto,auto,E,Protobelt,auto,Ult (they should be dead by half this combo. however if there super tanky your Q will be reset by the time you use your ult, so you can do the combo again)
