Posting this here because I'm hoping for dire help (,^-^,) Hello all! I am a returning player, and I have NO idea where to begin. There are so many new things I'm learning over time I am SO LOST. I stopped playing daily after Inazuma, and stopped entirely after Sumeru just to pull Nahida. I'm returning now that I have proper equipment to play Genshin on.

Anyway, I need help with teams! I have no idea which characters to focus on building! I plan on getting Columbina, regardless of if she's good with my characters or not. I just really like her! BUT I obviously need to build characters for late game content considering I have no new characters (other than Chevreuse I pulled on a whim.) Who aged the best, and who should I make into teams? Thanks ahead of time and happy new year!!!

Reddit won't let me add more than one photo?? So here's a list!
