Elder Titan is a melee strength initiator and teamfighter/utility hero. He is typically laned in the offlane, where his Astral Spirit ability allows him to secure last hits, bully lane supports, and scout out potential gank attempts.
His powerful ultimate and auras scale superbly into the late game, making him a fearsome teamfighter.
