Head-to-head Dota 2 7.41e win rate from ranked matches.
In Dota 2 7.41e, Viper wins the Riki vs Viper matchup: Viper beats Riki in 50.23% of 647 ranked matches.
Dropping a Smoke Screen on top of Viper completely shuts him down. He can't cast Nethertoxin to break your invisibility, and he can't use Viper Strike to slow you down. He's stuck in the cloud with a high miss chance while Riki gets free backstabs. This dynamic plays out across the entire game. Viper is a slow hero who wants to farm a lane by himself, making him a predictable and juicy target for a roaming Riki. Without a reliable way to see Riki coming or lock him down once he's on top of him, Viper gets picked off repeatedly before his team can respond.
