Tidehunter + Warlock

Why this works

Setting up a multi-hero Ravage gives Warlock a clear window to cast his spells. With enemies stunned and grouped together, landing Fatal Bonds across the group becomes simple. This allows the damage from Tidehunter, the Chaotic Offering golem, and any other allies to be shared among all linked targets. It's a straightforward sequence that makes it difficult for enemies to scatter or retaliate once they're caught, amplifying the impact of Warlock's abilities.

The game plan revolves around these two long-cooldown ultimates. Your team will look to force fights or take objectives when both are available, and play more defensively when they're not. Opponents will track these timers closely, trying to punish you during downtime or spread out to minimize the combo's effectiveness. Because this strategy is so dependent on specific timings and landing that initial Ravage, the overall advantage can be inconsistent against teams that know how to play around it.
