Hey,
I wanna present you My Skarner Build What i made whith one of my Friends, Skarner Is his Main champ. We Tryed builds of skarner especially for 3on3 but its also realy good at Top lane 5on5 and this one was definitely the Best one. Its a lil Tanky you can spam your Skills whith your passive especially your "Q" for that we made the atk speed items and manamune in this build. Your Q Scales on AP AND AD The Trinity is Realy usefull when u spam your "Q" you can get the Procc of shine every time when its ready! Your "W" give you some absorb what scales on AP it also gives you atk speed (CD reduce whith your Passive) and Movement Speed. That skill is a need to engage!
Your E is the last you will max couse it isnt that strong like the others, speceally whithout Hextech Gunblade.
Your Ulti is Realy Nice in Teamfights even for CC and the griped one can be focused as well.
I hope you enjoy this Guide,
Neeshka.

The runes i showed off to you can be a Little different:
You can use one AP quintessence instead of the AD!

For Ranked Play:
Your Mage resist runes can be changed to Armour if you know u need to play against an ad Champ on your lane!
Same if whith your Armour Runes if you play against ap champ!

The masterys are on full DMG i rly like this even for far game! You can change some skills into Defense tree if you like to get a lil more tanky at start, but the three penetration skills and the 5% ap and the 1.5% dmg is a need especially for Endgame.

First you Realy need FLash becouse this champ has no skill to jump over walls! BUT its also able to use gohst but then u cant go over walls even if it is to run away or hunting Someone.
The second Slot Should be used Exhaust if you got this Noone can Run aways From you! Ignite is also abel but not as good as Exhaust is. I would only use Ignite if i get a champ like Yorik or WW against me to reduce they´re heal!
In Jungle you even need the Smite!

If you need to fight in your base or at your tower You Can Use Your Ulti "R" to grip the opponent Into the laser Or into a tower! BUT you need to grip the enemy that is allready focused by the tower!
E->Q in a creep group heals u as well.
