How Chaos Knight and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Chaos Knight and Io win 51.85% of ranked matches when playing on the same team, over 2,615 matches.
Getting jumped by a Tethered Chaos Knight is a classic Dota gank. Io offers a lot of what CK wants: the extra movement speed to stay on a target after Reality Rift, and the durability from Overcharge to help him and his Phantasm illusions fight longer. Relocate lets them hunt for kills across the map, punishing anyone out of position. This combination is a huge commitment, though. If the gank target survives or has help, both Io and Chaos Knight are often stranded and easily killed. Their success relies on snowballing from those early kills, and if they can't secure them, the pairing doesn't offer as much to a teamfight as other combinations might.
