That's not them being on different tiers, that's just their Semblances being slightly different and Weiss having different profficiency as opposed to her sister. But yes, I'd say just say that it increases a person's skill with their Semblance, maybe lift certain restrictions in certain scenarios so longas it doesn't result in the affected Semblance becoming overpowered. Just little helpful things.

I think it's a bit simple and straightforward, but no one ever said that every Semblance has to be an artistic masterpiece with a whole book's worth of inspiration and explanations. It's good.
