One witch was complaining that the way her magic worked, her magical rings were embedded in her arm's flesh, so changing rings was very painful and time-consuming. If one ring didn't work, she couldn't just rip another out of her arm and try that instead, one after another, so she wanted to learn better how to determine what kind of opponent she was fighting, so she could pick the right ring for non-magical human, wizard, changeling, fairy, etc.

One wizard was complaining that finding rings was just a bother, but my mentor said that these days there's Taobao. The wizard knew some Chinese, but his Chinese wasn't great, so my mentor helped him: "No no, now you're saying you're a 'witch'; This character needs to be this, then it's 'wizard' ...".
