How Keeper of the Light and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Keeper of the Light and Io win 54.12% of ranked matches when playing on the same team, over 691 matches.
Pushing out waves from anywhere on the map creates a huge strategic advantage. Io's Relocate allows Keeper of the Light to channel Illuminate on a distant lane, clearing creeps and applying pressure without showing himself. This forces enemy reactions, opening up other parts of the map for your team to farm or take towers. The synergy extends to teamfights, where Keeper of the Light can supply Io with mana via Chakra Magic. This lets Io maintain Tether and Overcharge on a core for longer, often deciding a close engagement. This combination of global pressure and fight sustain is hard for most lineups to handle.
