Apollo is a charismatic support in Deadlock who buffs allies and debuffs enemies with musical ability combos. Sol's Blessing and Serenade allow him to amplify team damage output and peel for vulnerable carries simultaneously. Best builds favor Spirit Power for ability effectiveness with Vitality to keep him alive in the backline. Apollo excels in coordinated team compositions where his buffs and debuffs multiply the impact of skilled teammates. He is less effective in solo or disorganized contexts where his supportive abilities are wasted. A top-tier meta support for players who thrive in a facilitating role and enjoy enabling teammate success.
