Grimstroke + Magnus

Why this works

Setting up the big wombo-combo seems obvious here. Magnus lands a multi-hero Reverse Polarity, pulling enemies into a perfect clump for Grimstroke to unload on. The most reliable follow-up is Ink Swell, which gets a guaranteed stun and damage burst on everyone caught. The dream of a multi-hero Soulbind, however, is less consistent than it appears. The spell requires a primary target and then latches to a nearby secondary one; in the chaos of an RP, it can be tough to target correctly, and sometimes the heroes are stacked so tightly that the spell's effect is redundant with the initial stun.

Across a real game, this duo’s success is almost entirely dependent on Magnus. Before he has his Blink Dagger, Grimstroke and Magnus don't interact much. Once the initiations start, their impact is explosive but conditional. If Magnus fails to land a big Reverse Polarity, Grimstroke can’t create a fight-winning moment on his own. Enemies who play spread out to avoid the RP will also naturally neuter the Soulbind follow-up. The combo only amplifies an already perfect setup; it doesn't create new opportunities on its own, leaving their shared performance feeling fairly standard.
