How Chaos Knight and Viper perform as teammates in Dota 2 7.41e, from ranked matches.
In Dota 2 7.41e, Chaos Knight and Viper win 52.29% of ranked matches when playing on the same team, over 4,632 matches.
Ganking a single target is the main plan for this pair. Viper's slows from Poison Attack and Viper Strike can make it much easier for Chaos Knight to land his Reality Rift and follow up with Chaos Bolt. With the target stuck in place, they have to eat a lot of single-target damage from both heroes. For a brief window, this combination of lockdown and damage can be enough to secure a kill, especially against slippery heroes who might otherwise get away from one of them alone.
In practice, though, both heroes mostly do their own thing. They both excel at killing one enemy at a time, but they don't solve each other's core problems, like a lack of wave clear or teamfight presence. Chaos Knight needs farm for his big timings with Phantasm, while Viper is often pressuring a lane early. They might find a pickoff together, but in larger fights they can feel disconnected. Ultimately, they offer a lot of the same thing without covering each other's weaknesses.
