Necrophos + Io

Why this works

Facing a Necrophos tethered to Io is a frustrating experience. You commit spells and attacks, but his health bar barely seems to drop thanks to the constant healing he gets from his own kit and the Tether. This durability allows Necrophos to stay in the fight longer, constantly applying pressure with Heartstopper Aura. Io also provides a crucial speed boost, solving one of this hero's main weaknesses and making him much harder to kite. He can now chase down targets that would normally escape, turning their retreat into a losing battle against his sustained damage.

The duo typically looks to group up and force fights in the mid-game, turning Necrophos into a walking fortress that can be Relocated onto key objectives or heroes. The main counterplay involves breaking the Tether or focusing Io down quickly, as the combo is much less effective when they are separated. If the enemy team lacks the specific tools for this, they might find themselves slowly ground down until a Reaper's Scythe secures a kill and a teamfight win. The advantage isn't overwhelming because a coordinated team can often find the angle to split them up before they take over.
