So I had a friend of mine tell me he didn't like having to play skarner a little tanky to ensure his survival. This is my solution. I maximized skarners chase ability with a solid movement speed not to mention the proc on trinity force and the active on youmuu's ghostblade to add to his chasing arsenal. The high attack speed serves a few purposes. The first is of course to abuse his passive as much as I want, the second being that with 40% spell vamp I'm gaining health at a high rate, and the last point of the high attack speed is of course the most basic to make the most of 1.5 seconds of suppression. Also the item build certianly ensures your criting to make the most of each strike. I choose flash as a summoner spell because its always useful for closing ground or escaping not to mention its even more fun with his ulti. I picked ignite over exhaust because skarner already chases so well i figured the extra damage would be more useful. The final note I have is that I choose the defensive runes to ensure skarners survival. If however you find them to be unnecessary then feel free to replace them. I'd suggest armor pen marks and quints and then its pretty much up to you from their though crit. damage runes would probably be best.
