Here is a Genshin Impact team guide article on how to build a Venti team comp including details of the team members and free-to-play team.
In this team build, Venti is one of the best supports in the game that provides AoE Anemo DMG to interrupt enemies and group them which makes it easier for the team to apply elemental DMG.
Here is some team build that is suitable for him:
Venti Best F2P Vaporize Team Comp
This free-to-play team is a great option for a player who doesn't want to spend Primogem or a newbie who doesn't have any 5-star characters. Even though, this is a F2P team you still can maximize his potential as well. You can use Xiangling for Main-DPS that can output Pyro DMG with her burst to react with Xingqiu which can attach hydro element on enemies to create a Vaporize reaction and use Venti burst to group them up and continue dealing Vaporize DMG.
- Both of her skills can apply AoE Pyro off-field.

- Can buff allies' ATK as well as heal teammates.

This team comp focuses on maximizing the Permafrost reaction DMG by using Ganyu and Diona continuously applying Cryo DMG to react with Hydro from Mona to trigger Frost reaction and with Venti skill to extend frost duration.
- Apply AoE Cryo DMG and Using Charge ATK deal massive Cryo DMG which is great if you apply it on Venti burst combo.
- Deal Cryo DMG and create a Shield that can absorb DMG and her burst can regenerate HP of characters within the AoE.
- Her skill really shines in this team comp which can apply AoE Hydro DMG continuously to react to another element.
Venti Best Overload Team Comp
