Skarner is a support/dps. He can deal some damage and take some hits. The only flaw to him is he takes a bit to get tanky. You use your ultimate for ganks and team fights. You can take someone out in team fights so your team will have the advantage. He is good for both 3v3's and 5v5's. He is good against squishy and off-tanks. Skarner is moderate to play, don't expect to do fantastic when you play him for the 1st time. When your laning your should be spamming crystal slash in order to keep there minions down and good farming skill. You can also jungle with this build without having to much trouble. You want to you crystal slash and fracture together. Impale is good for leading and grabbing someone to kill and also finishing so they won't get away. I use crystalline exoskeleton mainly for speeding me up to land my ultimate and to get to turrets faster. It is also good if you are 1v1 someone. This is my first build so tips will help me out to make this an even better build.
