What does c1 change for chasca?

I accidentally got her c1 at 11 pity and I was wondering if this would make her teams less restrictive or anything like that. I've been using chasca/bennet/furina/ororon and sometimes Charlotte with ttds and 4pc tenacity instead of ororon, but I'm thinking of swapping out furina for mona and I was wondering if I could start using characters like xilonen now?
