How Medusa and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Medusa and Io win 45.35% of ranked matches when playing on the same team, over 1,848 matches.
Pairing Io with Medusa looks good on paper, but the lane itself can have trouble. Medusa needs a safe start to get her levels for Mana Shield and farm her first few items. Io offers healing and movement speed with Tether, but very little in the way of harass or kill threat to create space. This allows an aggressive enemy duo to pressure Medusa, zone her from creeps, and delay her timings. While a farmed Medusa with Io's support is a strong threat, getting to that point is the problem. The weak laning phase often sets them too far behind for the late-game potential to matter.
How this pairing performs across skill brackets — the duo's team win rate in recent ranked matches, split by average match rank. Ranks with too few recent matches are omitted. These rows use the last 30 days of quality-filtered ranked matches, all patches in that span combined — a wider window than the patch-scoped count above, so the per-rank match totals can exceed it.
