This is my first time making a build so i do not know how to make it all fancy so ill just explain everything in this one go. I don't expect much from this page i just wanna hear peoples thought. get the boots first, your choice in boots, i just choose mobility for faster arrivals with ghost as well.

Ok this is my favorite skarner build, its a lot different from others since it revolves around tears of goddess. Skarner is meant for spamming your abilities so with tears of goddess it will regenerate the mp while giving him more mp. next item u should build is manamune, which is a special item that gives him atk power based on mp. i choose warmogs first before sheen because he needs the health to survive. next i build sheen which based on how many times skarner builds q well that bonus will come in handy. You can go 2 ways with sheen.
1. sheen can be trinity force: yes it takes a lot of money but its somewhat worth it since u get the massive stats boost then again it depends entirely on situation. if you want u can prioritize trinity as it seems to be a great early game.
2. build it into lich bane, which i don't really use, unless its for chase.

next item is banshee: well if you face carrying ap opponents then build this after warmogs just in case. it helps block those stupid abilities: blitzcrank's arms, karthus' ulti...and so on.

next is atmas, judging by the health you got, atma wil give u armor and atk bonus which means you will have both mana and health giving you atk and wit the atk speed bonuses, towers will go down fast which phantom dancers comes in last if you want...
