How Night Stalker and Io perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Night Stalker and Io win 53.90% of ranked matches when playing on the same team, over 859 matches.
Tethering to an already-fast Night Stalker at night creates an impossible situation for most heroes to deal with. Io easily keeps pace, layering in slows and stuns from Spirits while Night Stalker applies his silence and slows to lock down a target. The constant healing and damage reduction from Io also allows Night Stalker to be far more aggressive than usual, diving towers and fighting multiple enemies without needing to back off. When you add Relocate to the mix, this pair can apply pressure anywhere on the map. They find a target, secure the kill, and get out, controlling the tempo from the very first night cycle.
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.
