Earthshaker + Viper

Why this works

Getting caught by this pair feels awful. A long-range Fissure stun creates a perfect window for Viper to place Nethertoxin and start applying his corrosive damage. For a hero trying to escape, the chain of stuns from Earthshaker layered with the constant slows from Viper’s attacks can make it impossible to get away. This lockdown potential is the main idea behind the duo, aiming to secure kills on anyone caught slightly out of position by preventing any chance of retreat. The follow-up damage from Viper is almost guaranteed, and there's not much you can do once that first stun lands.

The problem is their game plans often diverge. Earthshaker is always looking for that perfect multi-hero Echo Slam, while Viper is much more focused on suffocating a single, high-value target with Viper Strike and controlling a specific zone. In many teamfights, Earthshaker will find a great Blink initiation, but the slow-moving Viper isn't in position to contribute his damage right away. They can feel like two powerful heroes playing separate games on the same team, where one's ideal setup doesn't always match the other's effective range or target priority.
