Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
For the non-believers
I decided to try JG brand by using my normal brand Runes but changed up his masteries a bit.
It has worked as well as many JG main champs I have played and to be honest better than most.
Starting the jungle - in depth guide
Brand jungle is easy if you can kite. (Ability Order: Q - W - E) (LEVEL W first)
1st CAMP: Begin at gromp - if you can have someone tank it then leave shortly - Kill it with smite (you should not need to use a potion yet)
2nd Camp: Blue buff - auto Golem, drop W on whole camp, auto when golem walks out from the other 2 throw q to stun, kite as you do this.
Should have 2 or 3 pots available for camp 3 if you are doing this correctly
Camp 3: Wolves or Birds doesnt matter - utilize your stun
Camp 4: Red buff - start with E+Auto on red, then W, then Q to stun. Kite the whole time.
If you have done these camps correctly you should have most of your HP 70-80% and you should have RED and BLUE buff and be lvl 3
After JG Start
You can either gank or keep killing camps after taking red and blue
GANKING: its brand..... just do it.... but for those that want specifics - If you are close to your opponents in lane when you come in for a gank E Q W - If you are a little far away throw a W to ignite then land a Q to stun, Try to give the kills to the lane if you can.
1st Back: Hopefully you have secured a kill at this point or continued to farm hard after jg start - if so you should have enough to buy an AmpTome + Boots.
JG camps are easy at this point and so are ganks - No luck needed have fun!
