I used to play genshin before having no idea what to do next 😭
For Mari I’d say either cryo or anemo, though cryo is more of her personality while anemo leans more to her goal of not giving a fuck of what anyone thinks of her
Kel would likely be anemo, this time they’re trying to free themself from the need for validation and popularity ;-; pyro could also work though!
Elias would definitely be hydro, he’s a genuinely good guy who looks out for others, even if it means hurting himself, idk what else would fit so ye ;-;
