Underlord + Weaver

Why this works

Choosing a partner for Underlord often means finding someone who can capitalize on his team-wide teleport and area control. Weaver's own kit makes him a self-sufficient hero, which can create some friction. His high mobility from Shukuchi means he rarely needs a ride from Fiend's Gate, and he prefers to skirmish on the edges of a fight rather than stand and deliver damage inside a Pit of Malice. While Underlord wants to group up and create a fortified position for his team to fight from, Weaver is naturally inclined to split the map and find solo pickoffs.

This dynamic can make teamfights feel a little disjointed. Underlord might be trying to herd enemies into his Firestorm, while Weaver is already deep in the backlines on his own mission. Atrophy Aura certainly helps Weaver survive a bit longer in these chaotic engagements, and the root from Pit of Malice can lock down a kill for him if the timing is right. Still, the team often has to consciously decide whether to play around Underlord's slow, deliberate pace or to follow Weaver's more aggressive, hit-and-run style, as the two don't always point in the same direction.
