Take one pot and one pink ward, place your pink on your red and go for your gromp and blue, when you go lvl 2, go to enemies red, ward it, if he started from blue buff you have enough time to steal it, then you are level 3 so you can make an early gank, if enemy jungler started from red buff, go and take your red, if he tries to take your red, your vision will help your team to kill him. Spend half time in jungle and half time on ganking, you should always avoid been visible to enemies, cause they can easily cancel your ulty and kill you. If enemies have lots of cc and u die easily rush zhonyas, or else, rush rylai's cause with the slow effect you have more damage thanks to the masteries.

Pros: cleans really fast jungle camps, early gank potential, can burst any fed carry
Cons: can be easily countered by wards, almost any champ can cancel his ulty, needs good communication with team for engaging

Try to let your team engage first, so they wont focus you and you can fear and silence the carries without getting the enemy cc in the face :) press q and win

DONT USE ULTY WITH SMARTCAST!!!
