In the new season we gotten new tank items. And I wanted to make a fun build since Sett is also a tank. In this build you'll only need 2 AD items which are Titanic Hydra and Black Cleaver to shred enemy armor. Titanic goes really well with this build since the mythic Heartsteel gives a lot of health. And Titanic gives you more AD based off your bonus HP. And having Grasp gives you permanent HP each time you proc it.
