Why this duo works
Veigar players recommend Xin Zhao as an AD/tank jungler who can cover Veigar's early game through counterganks and early skirmishes. During ganks, Veigar's cage constrains escape routes and can stun a target that crosses its edge, giving Xin time to approach and combo without spending Audacious Charge(E) just to reach them.
Playing the duo
Set up ganks with Event Horizon(E) first; if the target is caught at the cage edge, Xin can walk into range and keep Audacious Charge(E) for a target who needs the dash.
Event Horizon(E) stuns enemies that cross its edge; Veigar players note that a jungler can approach a caged target and combo without using a gap closer to get into range.
