This Sion build is for a Jungle sion, your start with "cloth armor" 5 heath potion. you start at Blue buff at Jungle(Get a good pull), after wolfs. After that you go kill Wraths, and take red(Sometimes very hard!). Then you go get Golems. You should now to back and get Vampiric Scepter and go gank in a lane.

I think this Sion build as a fast leveling sion there got hp for Tanking and damage for kills, try to hold low profile to level 11 where you got "Trinity Force" then you can kill (maybe good idea get "Trinity Force" before boots, then it goes better Jungle)

Good idea to wait to go vs 2 until you get Phantom Dancer.

When you have full build you should have no problem catching your enemies because of Boots, Trinity Force and Phantom Dancer

PsYcHoS ZapToX ;)

Hope your will enjoy my build, this is the first build i have made so please say if your need something to know about my sion build :)

It is importen that you'll get a lot of creep kills. Other wise atmas wont works as good. When i play Sion jungle i try to farm alot.

Sometimes your enemy team find a way to cc you, but dont worry, you'll get them when you have got phantom dancer. and in the end the infinity edge :)

Pros / Cons

Pros:
-Pretty fast clear times
-Very reliable ganks with his stun + Red buff slow
-Very strong late game
-High damage output
-Very safe jungle route with runes
-Good team sustain with ult late game

Cons:
-Ignites can shut you down pretty hard
-Pretty reliant on red buff to gank, but can gank without it
-Very dependent on his ult
-Can be counter jungled early if not careful

I choose smite because we are jungling, and flash because those clutch "flash out of nowhere and stun" ganks are great. Exhaust is also a viable choice, but I wouldn't take anything else.

He doesn't need ignite as he does enough damage. Ghost is useless because you have 450+ movement speed late game. Heal isn't needed, you have tons of lifesteal. Clarity is worthless since you have so much mana from blue buff and new Sion buff. Rally and revive are self explanatory.

Ganking on jungle Sion is pretty easy, and works well. Let your lane mates know you want to gank, put your shield on, and either walk/flash in and stun. Once they are stunned, beat them down with your lumberjack axe (optional) and pop your shield for tons of burst damage.

Don't be sad if you don't always get the kill, making someone waste a summoner spell or recall still gives your team an advantage.

For the best results, make sure you have red buff before you gank, it will give you a ton more kills.
