How Night Stalker and Viper perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Night Stalker and Viper win 50.91% of ranked matches when playing on the same team, over 493 matches.
Stacking all of Viper’s slows on top of a Void from Night Stalker makes escaping nearly impossible for a single target. This pairing excels at hunting key heroes once the first night hits. Night Stalker can use Dark Ascension to create a ganking opportunity, find a target, and apply a silence with Crippling Fear. This gives Viper a perfect window to get in range and apply Poison Attack and Nethertoxin without any return threat. The plan is straightforward: find a victim, pin them down with an overwhelming amount of slows, and remove them from the map before a teamfight even begins.
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.
