How Dark Willow and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Dark Willow and Io win 49.76% of ranked matches when playing on the same team, over 2,287 matches.
Struggling to find the right partner can leave this pair feeling a bit directionless. Io’s kit, especially Overcharge, is designed to turn a physical damage dealer into a raid boss by boosting their attack speed and survivability. Dark Willow, on the other hand, is a spellcaster who plays around control and magic burst. While Io can certainly use Tether to save a fragile Dark Willow or help her reposition for Bedlam, his most powerful buffs are simply not being used to their full potential. The result is a partnership that can function and get kills with Relocate, but it often lacks the focused power needed to consistently take over a game.
