Weaver + Witch Doctor

Why this works

Landing a full Maledict or Death Ward channel depends on the target being held in place, and Weaver doesn't offer that kind of lockdown. His entire kit is built around mobility and kiting with Shukuchi, not pinning someone down for a teammate's big spell. This forces Witch Doctor to rely entirely on Paralyzing Cask for setup, which is too unreliable to guarantee a kill on its own. The duo simply lacks a surefire way to start a fight and keep an enemy from escaping their damage.

Throughout the game, this lack of synergy means missed opportunities. In lane, a target can often survive by walking away after the initial burst wears off. While The Swarm's armor reduction does increase Death Ward's physical damage, the combo is inconsistent without another hero providing a hard stun. In larger fights, Weaver wants to hit from the edges and use Time Lapse to reposition, while Witch Doctor needs the fight to stay in one spot. They aren't actively working against each other, but their game plans don't overlap enough to create a strong lane or ganking pair.
