This is my first build that worked for me so i hope it works for you. I have tried a lot of the other guides to playing Sivir or any other characters you may play. So i get it that not all of them are great so please do not get mad if this guide does not work for you. good luck and good hunting.

first lets start by making boomerang blade full along with ricochet and getting on the hunt. Once boomerang blade is done you can start to finish ricochet and start spell shield, after this finishing your skill levels is up to you.

buying your items is difficult so one you have bought the first three (buy in the order i have) buy B.F. sword then Tiamant then go back and then finnish in the order i have specified.

your choice whatever you like best only because i do not use anything else other then maybe flash

you must have a good teammate that likes to play a tankish role and scare away you enemies for this character to work so get a friend and have him help take of some of the pressure.
