Viego Jungle and Viktor ADC win 51.0% of 1,491 Low Elo games together, -0.4 points vs expected, 2-patch window 26.19-26.20.
Researched on LoL patch 26.20. Tips are written to hold at any rank; stats come from Low Elo ranked games up to patch 26.20.
Playing the duo
Viktor's W can hold a target in its field long enough for Viego to land Spectral Maw(W); Viego mains specifically value hard CC that guarantees his own stun and follow-up.
How to play as Viego
Let Viktor's W slow or stun first instead of starting the fight alone; follow with your own W and reserve R for the low-health target that can start your cleanup.
How to play as Viktor
Place Gravity Field(W) on the target after Viego commits or after allied CC lands, then keep Arcane Storm(R) on the trapped area to help secure the first takedown.
