This build was made to optimize early game level 1-6 AP damage. End game with a lot of survivability. Items are not meant for every type of matchup. This particular build is meant for survivability with an emphasis on HP. It incorporates some movement speed to get out of situations, and armor for when you get jumped on, including a clickable invincibility. For instance if you find yourself up against a lot of AD/AD jungle go with Zhonya’s Hourglass after Rod of Ages. If they are more AP go for Abyssal Scepter after Rod of Ages. Buy items according to situational matchup. I almost always buy Rod of Ages first, that being said if you can’t get the Rod of Ages in a timely fashion buy a few Doran’s rings, never more than 3.
