How Venomancer and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Venomancer and Io win 48.22% of ranked matches when playing on the same team, over 2,675 matches.
Failing to build an early advantage is common with this pairing. Io wants to amplify a partner's ability to get kills with Relocate and Overcharge, but Venomancer lacks the lockdown or burst damage to make those ganks stick. The attack speed from Overcharge does little for a hero who relies on damage-over-time spells to be effective. This fundamental mismatch leaves the lane without kill threat, making it difficult to create space or pressure the map. Ultimately, Io is simply looking for a core who can better translate his buffs into immediate, decisive action, and Venomancer isn't that hero.
