for the most part i took this build from another top rated and made it my own like everyone else does. for my runes as one can see changes must be done to make it better and i think crit runes or cool down runes would work better then ability power. i have a mix but for simplicity sake i put it as all ability runes.

The main thing that i have seen that works and so i kept it is always get sheen first. even before boots. after that the sequence is explanatory. trinity as most have found with poppy, is a must to start it out. extra damage/slow/atk/crit......its all good. After that i followed the build pretty closely to the one i assimilated, and its work out pretty well. i will say the order can always change as one see's fit depending on how the fight is going. if AP is a problem i'd consider getting banshees.

feel free to change anything to meet your needs.
