Grimstroke + Venomancer

Why this works

Facing down a wall of slows and constant damage can feel oppressive, and that's the main idea here. Grimstroke's Soulbind sets up a double-hit for Venomancer's spells. A duplicated Venomous Gale can slow two key heroes, making them easy targets. The combo seems appealing on paper, doubling up on some of the most annoying abilities in the game. However, the synergy with their ultimates is often redundant. Poison Nova already covers a massive area, so hitting a Soulbound pair with it doesn't really change a teamfight dynamic. Grimstroke works best with high-impact single-target spells, and Venomancer’s kit is built almost entirely around area damage.

The laning phase can be a source of constant pressure, but both heroes are quite fragile and lack escape mechanisms. If caught out, they fall over quickly. Later in the game, their entire plan relies on Grimstroke landing a good ultimate to kick things off. If the enemy team initiates first, or has ways to dispel the slows and sustain through the poison, the whole strategy fizzles out. This pairing provides a lot of sustained, non-lethal damage, but struggles to find the burst needed to secure kills on its own, making its success heavily dependent on the rest of the team's draft.
