Head-to-head Dota 2 7.41f win rate from ranked matches.
In Dota 2 7.41f, Io wins the Naga Siren vs Io matchup: Io beats Naga Siren in 51.53% of 4,446 ranked matches.
Playing around Song of the Siren becomes a positioning puzzle against Io. Relocate can be used to pull a core to safety before the song ends, completely negating Naga's setup. Conversely, a well-timed Song can catch the heroes Io brings in, turning their aggressive play into a liability. Outside of that major cooldown trade, Io’s Spirits offer a consistent way to thin out illusion pushes, preventing Naga Siren from easily taking objectives. Still, Naga can dominate the map with her farming speed, and a timely Ensnare can lock down Io's tethered partner. The outcome often depends on which hero's team better executes around these key timings and cooldowns.
