How this matchup plays

Using Disruption on a hero tethered to Io is often a complete disaster. The resulting illusions are also connected by Tether, gaining its shared movement speed and the damage reduction from Overcharge. Instead of creating fragile targets that melt, Shadow Demon creates durable, fast-moving illusions that are hard to kill and can't be kited. This completely undermines his primary setup spell, turning it into a liability that can sabotage his own team. Even Demonic Purge on Io’s partner isn’t enough to fix this. The fundamental interaction makes it incredibly difficult for Shadow Demon to isolate and burst the target that Io is enabling.
