Shadow Fiend + Warlock

Why this works

Stacking Chaotic Offering with Requiem of Souls feels like it should be a powerful combination, but the two ultimates can often be redundant. Warlock's Golem is frequently a fight-winner on its own, making a follow-up Requiem feel like overkill rather than a necessary part of the plan. While Fatal Bonds certainly helps amplify the damage from Shadow Fiend's Shadowrazes, the core issue is one of setup. The Golem's stun is brief and Warlock's other spells don't provide the kind of reliable, long-duration lockdown that a Shadow Fiend needs to guarantee his most impactful spells connect perfectly.

This pairing often feels disjointed as the game progresses. Warlock typically plays a passive lane, which doesn't create the pressure a Shadow Fiend needs to snowball from the mid lane. In teamfights, their positioning goals conflict. Warlock wants to stay on the far back lines to channel his spells safely, while a magical Shadow Fiend needs to find a risky forward position for his ultimate. This means they often fight in different zones, succeeding because one of their big spells was enough on its own, not because they enabled each other in a special way.
