Best Team for Venti in Genshin Impact
Team #1: Ayato International
Venti is a very odd character. He is either must play or useless based on the type of enemies you have to deal with. If there are many enemies scattered around, then Venti is OP. If there is a boss or few heavy enemies, then Venti is useless. Consider using him with this rule in mind, he also works just fine in any team with a flexible slot.
Team #2: Morgana (Ganyu Freeze)
Ganyu takes advantage from the Freeze reaction, Cryo resonance and 4pc Blizzard Strayer to gain 55% Crit Rate (+20% from A1 passive = 75% Crit Rate on her charged attacks). She is the main damage dealer and her numbers get furtherly increased by Cryo swirl and her own passive talents. This team mostly uses Ganyu's burst as a main source of DPS together with Venti's, as both have quadratic scaling (more enemies hit = more damage). Note: Bosses can't be frozen, so this team is not effective against them.
