If you guys don't know already, venti is getting a rerun with ayato next patch. (2.6 update) Then Ayaka is right after. Venti is a character definitely worth considering to get. He is my favourite anemo character in the game, he's also super fun to play, does a lot of dmg and his burst is so satisfying to use. His element skill is useful for exploration as it provides a wind current when you hold it. However, his weakness is that he isn't very useful with single target enemies compared to the other 5 star anemo character, Kazuha. If you're planning to pull Venti or have him already, this is a build guide to utilize venti best, and so you know what to pre-farm if needed (:
Materials
These are his levelling up materials (for ascension and talents.) You need to fight the anemo cube, and defeat a lot of slimes. He also needs the ballad books to level up his talents, these are open Wednesdays, Saturdays and Sundays. You also need to fight the wolf boss to get those talent levels up!
You also need to collect Cecilia flowers which are here on the map. (Yes they are very annoying to collect as they're quite high up, but suits venti right 🙃)
Weapons
Venti's best weapon is the 4 star weapon, the stringless. This is because it provides more EM, as well as skill and burst damage (perfect for Venti!) I sadly only have Refinement Rank 2, Definitely get this to Refinement Rank 5 if you can! If you do not have this weapon, other options are any weapons with Elemental Mastery Substat or Energy Recharge Substat. (Or crit- depending on your build)
Teams
Venti is quite a flexible support, he can go with almost any elemental team. I use my venti with my Ayaka as he groups enemies quite nicely for her to use her burst. It's also quite nice using him with DPS bow characters (e.g. Yoimiya, Ganyu), or catalyst users (Mona, Yae) as they can reach the enemies which get trapped in his burst high above. Or you may use him with another anemo character for anemo battery recharge so their bust comes up faster, which is useful for Xiao. (As he provides lots of anemo particles) However, as I stated previously, a great thing about Venti is that he's very flexible. So just use him with characters that you enjoy playing with, as this game is all about having fun (:
Artifacts
The best artifact set for Venti without a doubt is the Viridescent Venerer 4 piece set (Like it is with most anemo characters.) This set is very strong and decreases resistance for enemies, increases swirl dmg, and provides anemo dmg as well. Making Venti a strong and useful support for your team!
Keep in mind, triple EM build would best for Venti, however my luck in that domain is terrible and I barely got any Elemental Mastery pieces 🥴 so I had to go for the latter option which is crit build Venti
Main Artifact Stats:
For the Sands, I went for Atk% (you may also use Energy Recharge or Elemental Mastery)
For the Goblet, I went for Anemo DMG Bonus, however Elemental Mastery is also beneficial.
For the Circlet, I went for Crit. But again, Elemental Mastery is also good. I heard Atk% also works well.
Artifact Substats:
For substats, you're looking for Atk%, Elemental Mastery, Energy Recharge OR Crit dmg and Crit rate
These are my full stats on my Venti. However yours may look completely different, depending on whether you go for a crit build, or EM build. My Energy Recharge is quite low, this can easily be fixed if I pair Venti with Baal or another anemo character to provide more anemo particles for him. Nonetheless, goodluck on your farming! 😊 If you need more guidance or have any questions about venti or anything genshin related, dont be afraid to leave a comment! I'll try my best to answer. Also if you have any suggestions on who I should make a build guide on next, Let me know as well.
