This build is for the Mummy DoublestunGG playstyle, if you rename yourself to DoublestunGG there Should gain a bounce +5.99% total AP. So with all the calculations this build gives us 1860.554982 AP.

Gameplay:
How this build works depends on your BandageToss, practice with it because with the 80+60 per lvl put in magic dmg on your Btoss. So 15 lvls into it gives you about 920dmg! Btoss also has an awesome 1:1 AP ratio, so that gives you about a good 2k Btoss. And if they have MR then just AA using lichbane proc. Gives you a tremendus 920+1860+15%- enemy magic resistane, ontop of his -MR passive, a good 3000ish Btoss.

P.s. don't forget to ignite/place rally for additional ad/ap.

Use this build, and you will always win ever single game of LoL no matter what!
