How Shadow Demon and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Shadow Demon and Io win 42.96% of ranked matches when playing on the same team, over 135 matches.
Struggling to secure objectives or control the map is common with this pairing. Both supports need a lot of resources to come online, and there usually isn't enough farm to go around for both Shadow Demon and Io, leaving one or both under-leveled and ineffective. This creates a tempo disadvantage from the start. In teamfights, their abilities don't combine well for kills. Io wants to amplify a high-damage core with Tether, while Shadow Demon's Disruption sets up for burst that Io himself cannot provide. You end up with two defensive supports who can save allies but lack the tools to initiate or apply pressure.
