Io Synergies (7.41f)
Best heroes to pair with Io in Dota 2 7.41f, and the worst pairings, ranked by team win rate over ranked matches.
Io is the ultimate carry-amplifier — Tether's regen and speed plus Relocate ganks let an aggressive core dominate, then teleport home. It pairs best with mobile, dive-happy carries: Spectre global-Haunts off Relocate ganks, while Slark snowballs stat-steal with Tether sustain, and Tidehunter gets Relocated into the perfect Ravage. Give Io a snowball carry and the Tether duo bullies the map from minute one.
