Io + Zeus

Why this works

Getting chased by a Zeus who suddenly has a major speed boost can feel impossible to escape. Io gives Zeus exactly what he lacks: mobility from Tether and durability from Overcharge's damage reduction. This lets the normally fragile mage play much more aggressively, finding better positions for his spells without being an easy target. The global threat of Relocate is the main highlight, allowing the pair to appear anywhere on the map for a sudden burst of magical damage on an isolated hero. Zeus gets nothing from the attack speed bonus, however, which tempers the duo's overall offensive pressure.

The game plan for Io and Zeus is to use that Relocate potential to secure early kills and build a lead. The combo is strongest before enemies have key defensive items. The moment opponents complete a Pipe of Insight or cores get their Black King Bars, Zeus's impact is significantly reduced. A simple silence on either hero during a Relocate gank can also completely shut down the attempt. Because the strategy has such common and effective counters, the game often hinges on whether the pair can snowball before the other team has a chance to itemize against them.
