Beastmaster vs Io

How this matchup plays

Picking Beastmaster into an Io is a difficult decision because Io’s kit is perfectly designed to foil Beastmaster’s game plan. The core problem is Primal Roar. Beastmaster relies on that long stun to isolate and burst down a key hero, creating an opening to push with his army. But if Io is tethered to that target, he can use Overcharge to provide a massive amount of damage reduction, making the hero surprisingly tough to kill. Even better, Io can cast Relocate on the stunned ally, teleporting them to the fountain before the roar's duration even ends.

This interaction forces the Beastmaster player to completely change their approach. Instead of using Primal Roar for a guaranteed kill, they have to use it to initiate a less favorable fight, hoping to bait out Io’s defensive abilities. It often means having to target Io himself or a less critical hero. Meanwhile, the Io player’s job is simple: stay connected to the most likely target. As long as Io is in position to react, he denies Beastmaster the ability to get clean pick-offs, which stalls out his entire objective-focused strategy.
