this guide has been tested over and over again in my ranked games and my friends use the exact same build so i know that this build works!! i usually becomes a huge part of my team's victory due to my good damage and amazing ability to tank damage. early on your basically a jungling support champion but later you become a bushwacking monster with the proper use of your ultimate because nunu scales so amazingly well with AP you dont need much so if you so tanky the cant kill you how would you ever lose?!
