Skarner is a grait jungle hero with a high output of dmg during the game.In the late game with this build he is practicly unstoppible in team fights.Grait farmer,catcher,killer,ganker,jungler.

Pros

Great Jungler
Great Farmer
Great Ganker (if u time right)
Great Chaser and Runner


Cons

low mana on start

I use Theese Runes

Red:Greater Mark Of Desolation x9.. in jungle very helpful,and when kill tanks
Yellow:Greater Seal Of Fortidude helps in jungle and in ganks
Blue:CDR ofc so you have lower coodlown on W and E
Quint:Desolation Also for junlge and killing tanks

I use my masteries 21 9 0

21 in offence because i play him as tanky/hp/dps
and 9 in Defence because of bonus armor and mr in the jungle

so 1st you buy cloth Armor and 5 bottles

than you go : 1 Blue golem(ask for pull its very usefull)
2nd Wolf camp
3rd Wraith Camp
4th Double Golems
Than Base And buy LongSword and madreds razer if possible
Than Go Back And Pick UP RED and you are rdy for ganks

So about this 1st to be a good team player and a jungler always time when u kill the dragon and baron time when you killed em and when will they spawn usualy BARON SPAWNS EVRY 7 MINUTES
AND DRAGON SPAWNS EVRY 6 MINUTES try killing em as soon as you can because they bring great amounts of money for you and your teammates and baron gives you a nice wining buff...

and also try taking enemys jungle as much as u can if they dont have a jungler and even if they do whatch out your and they buffs

Well skarner is a Great champion to play and highly amusing...WHEN YOU READ THIS BUILD U WONT BE A GOOD PLAYER WITH IT INMIDIATLY JUST PLAY HIM FOR A LITTLE BIT YOURSELF 1ST AND DONT ALLWAYS FOLLOW THE BUILD I WHATCH WHAT OTHER PEOPLE BUY I COMBINE STUFF AND TRY MAKING THE BETTER BUILD I CAN... So lets Start Out with skarner At begean he is relativly good,but make sure that u get o warmongs armon and trinity force as soon as you can because after those items game starts being easy..
