Targeted pick with immediate burst
Vi gives this type of composition exactly what it needs: a target that cannot simply walk away. Ahri can prepare or follow the lockdown with charm, while Kai’Sa benefits from forced contact to enter faster onto a target already marked by the play. The key point is conversion speed. If Vi ults a target and burst arrives immediately, the enemy has no time to organize peel. The combo then becomes a map decision, not just a flashy all-in.
How to play it. The target must be called before the objective, and key spells should be held for the moment Vi locks someone down. Ahri or Kai’Sa should not waste their threat on the frontline if Vi is looking for the carry. After the kill, the call must be immediate: dragon, Herald, Baron, or tower depending on position.
Chain engage and zone control
Vi forces a path and landing point, which makes zone follow-ups much easier to place. Galio can turn her entry into a real defensive or offensive impact point, while Orianna can punish enemies stacking around the locked target. This synergy works because it covers Vi’s main weakness: the moment where she is advanced after her R. Instead of being alone in the middle of the enemy team, she becomes the trigger for a second wave of control or damage.
How to play it. The duo must avoid launching two separate engages. Vi should identify the target, then Galio or Orianna should hold the key spell for the moment enemies group around the impact. The goal is not only killing the target: it is also punishing those who come to save them.
Protection and repositioning after engage
Even though Vi is an engager, she greatly appreciates allies who can stabilize the fight after her entry. Janna does not necessarily make the first impact more explosive, but she can prevent Vi from being instantly punished after R, protect the carries following the play, and break the enemy counter-engage. This synergy is especially valuable when Vi does not need more burst, but a safety net to turn a correct engage into a sustainable fight.
How to play it. Vi should communicate her entry angle so Janna knows whether to protect the backline or support the melee. The goal is not for Janna to engage with Vi, but to stop the enemy from turning the fight immediately after the lockdown.
