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.
I have been working on this build for a few weeks now, always get good scores, but like anything else it really has to do with timing. I will try to upload a photo of my route for you.
Smite? Well I have never tried to jungle sion without it. so thats your call I say always get it. Ghost is to catch your enemy. flash really wouldnt be the best with this champion.
I use these runes most of the time, but you can also use Crit Dmg Marks and Quints, by then end you should be criting around 1300 a hit. the Dodge i use to help stay alive in combat areas, the dodge works well with your shield. that little attack speed will help you out in the early jungle.
I believe its pretty much easy said. you can do 21/9/0 its a little slower but i have done it, I have also played with 14/9/7. all of them work but i seem to like 21/0/9 the most.
I myself max out (e) Enrage first and never shut it off. When i have you place a point someplace else it goes into the (w) shield, but always place a point it (Q) at level 4 so that you can gank easier.
Most of the items arnt really able to be traded out. you can take the merc treads and get B greaves but i find the ult is best with the Mercs. and you get enough attack speed by the end of the round.
Creeping / Jungling
I have a few photos to upload but im working on that later atm i gotta go, start at 2 golems, move to wrathes, wolves, blue, then you can do the 2 golems, wrath, and wolves again heal then do blue, when you hit level six make sure you have blue do dragon. you dont need to blue to do dragon but it helps.
