Hi all!! here is my build for Skarner jungle this build will make you near unkillable, while still dealing moderate damage, soaking tons of damage, getting life back and CCing and being a great utility.

for runes it may seem a little messy but skarner has great base stats for defense, attack speed will help you get more attacks of reducing the cooldowns of your Q getting more of due to resets which will in turn regen more health as a result of the mastery.

the scaling health is great as it scales throughout the game, if you follow this guides guild you will end up with over 5k hp.

CDR speaks for itself more Qs more W (shield) more Es (slow and stun on hit)

then you have scaling mag resist to make up for what you missed on the rest of the runes and also armour for quints because surviving is important.

The Masteries speak for themselves if you read them, the only one i will explain is is Courage of the Colossus, more or less you want to be spamming your abilities like mad, including your E and getting the auto hit, meaning your going to be CCing alot, so you get a good shield out of it for 7 seconds.

items are rather basic tank, good balance between Armor and MR and end build plus a Elixer of Iron you will have over 5k health it also allows for great movement speed to be able to get in and out, and catch people with your ult quick smart and get back to your team.

Skarners Jungle and CSing early is rather slow, but when you get your iceborn gauntlet CSing and jungle is a breeze

I usually start on the right side of the jungle and play it by ear, very standard jungle, and the new jungle in the pre-season is rather easy to farm and navigate.

Pros:
Extremely tanky
Hard to Shut down
Strong Mid/Late game
Good CC
Great team play
Good isolating Priority enemy targets

Cons
Weak Early Game
Slow jungle/farming early
Moderate Damage mid/late game
Can be Counter Jungled early due to slow jungle.

In summary Skarner is a great tanky jungle, with great team dynamic and good CC and amazing survivability and can bring a game back from the brink of loosing, if you can get over the slow early game and jungle, he becomes a great mid/late game and can carry a game simply through being a immovable wall with an ult that can CC and drag out an opponent of your choice and bring them into allied fire, a spam able shield a spam able Q that deals decent damage with the item build that also gives life back on hit due to the masteries, and an E that is a slow and on auto attack a stun.
