Head-to-head Dota 2 7.41f win rate from ranked matches.
In Dota 2 7.41f, Chaos Knight wins the Chaos Knight vs Io matchup: Chaos Knight beats Io in 52.88% of 9,256 ranked matches.
Saving a core from a Chaos Knight gank is where Io can disrupt his entire game. The speed boost from Tether can pull an ally to safety right after a Reality Rift, and Overcharge makes them tough enough to survive the initial illusion burst. This can completely stall out Chaos Knight’s attempts to snowball off solo pickoffs. However, Io itself is extremely fragile. A smart CK player can simply switch focus and delete the Wisp in a single stun, turning the attempted save into a liability. The matchup often hinges on who gets the jump first and whether Io is positioned safely enough to help without becoming the primary target, leading to very volatile fights.
