The world of Genshin Impact is filled with history and lore that can sometimes be difficult to keep track of. There's also an ever-growing roster of playable characters, each with their own unique ties to Teyvat and the game's central plot. In terms of lore, many characters could be used in battle, but some are definitely better than others. Here is the best team build for players who want to focus on Genshin Impact's lore.
Of course, a lot of this depends on which characters players actually manage to pull. Beyond starter characters and the occasional freebie, most characters have to be pulled through the RNG-based Wish system, which takes a lot of luck (and Primogems). The arrival of Version 1.3 may also alter which team builds are best for lore, since Xiao is pretty important to the overall story of Genshin Impact.
Due to the fact that new playable characters are added into Genshin Impact all the time, team builds are always changing. However, some characters are definitely more important to the history and lore of the game. From a storytelling standpoint, characters like Jean, Amber, and Kaeya make a lot of sense because they're constantly assisting the Traveler. However, these characters aren't nearly as good as some of the 5-star Banners players have acquired since launch.
Building A Genshin Impact Team With A Lore Focus
It's important to remember that the best team builds in Genshin Impact are ones that can cause Elemental Reactions, so choosing users of different Elements is really important. Ideally, this means keeping a Pyro user and a Cryo or Hydro user in the party for Melt or Vaporize. Keeping the Traveler in the party is necessary for players concerned with realism and the story, and keeping the Traveler attuned to the Geo element works best. This way, Venti can be used, since he's an Anemo user just like the Traveler at the beginning of the game.
Venti is the embodiment of the god Barbatos, so it makes sense within lore to keep him in the party, and he's also a great fighter already. Ganyu is a half-adeptus, half-human - and that makes her important to Genshin Impact's lore as well. Ganyu is a Cryo user, which means a good Pyro user will need to be added to this team build in order to take full advantage of the Melt Reaction. Diluc makes the most sense, because he's incredibly powerful and a famous warrior from Mondstadt. So, he's a great addition to this team, and it makes sense from a lore standpoint.
This means the best team build for Genshin Impact's lore is probably Venti, Diluc, Ganyu, and the Traveler. However, most of these characters are extremely rare, and starter characters like Kaeya, Amber, and Lisa make sense too (they just aren't especially powerful). For anyone looking to stick closely to the lore in Genshin Impact, this team build is one of the best.
