Chaldea's Master uniforms are Mystic Codes that have some spells built in, so I can use those, but otherwise no.

But oh, look, a question she actually has a good answer for, thanks to Waver's own counterpart!

The version of you that I met said mine were similar to his, I think?

In other words, pretty low tier. And unlike Waver, Ritsuka does not have the cleverness and single-minded focus to make up for that with sheer study.
