Why this duo works
When Aphelios has Gravitum, its slow and root give Pyke a coordinated catch window, and Pyke's execute can grant extra gold to an assisting Aphelios. A Pyke player specifically describes the Gravitum–Bone Skewer setup as useful when the pair coordinate, while Aphelios players warn that Pyke's roaming can leave the lane exposed if they do not account for his weapons.
Measured in High Elo: this duo wins 1.9pp more often than expected over 2,140 games.
Playing the duo
Gravitum attacks slow targets and its Weapon Ability(Q) roots enemies already slowed by that weapon; Pyke's Bone Skewer(Q) can pull a target and Phantom Undertow(E) stuns enemies along its path.
Death From Below(R) executes low-health enemies and grants additional gold to an ally who assists, which can help Aphelios reach his item spikes after a successful catch.
How to play as Aphelios
Tell Pyke when Gravitum is available and coordinate before committing to a catch; follow his Q or E only when the target is within your reach and your current weapon can contribute.
How to play as Pyke
Check Aphelios's weapon order and wave before roaming; Gravitum gives him a root setup, while leaving him alone without a safe wave can expose him to a dive.
