Head-to-head Dota 2 7.41e win rate from ranked matches.
In Dota 2 7.41e, Crystal Maiden wins the Crystal Maiden vs Io matchup: Crystal Maiden beats Io in 55.09% of 1,129 ranked matches.
Getting caught by a Frostbite is especially dangerous for Io. While the root doesn't stop Io from casting its spells, it does prevent the forced movement from Tether, meaning it can't pull itself to a fleeing ally to escape. This isolation often leads to a quick death. In teamfights, Crystal Maiden's whole plan punishes Io's positioning. Io needs to stay close to a partner to be effective, which clumps them together perfectly for a Crystal Nova slow followed by a full Freezing Field. This forces Io into an awkward spot, unable to fully commit to its partner without putting both of them at risk from Crystal Maiden's area damage.
