Hi, thank you for the input :)

I'm not gonna lie, my character is heavily inspired by the Chimera in [url=https://manganelo.com/chapter/fatestrange_fake/chapter_7]Fate Strange/Fake[/url]

What I have in mind, while knowledgeable and quite competent, her master has a very limited pool of prana, so he took her under his wing for the sole purpose of using her power to supplement his. That's why the first thing he taught Li is how to pour magic into paper talismans, for him to use. So the complex working of the talismans are set by the master, and Li will only have to pour her magic in so that the talisman would be complete. Over the course of several years, Li had a very limited understanding on how to make them herself, but she can only make very limited variety of 'em (specifically, binding spell).

So for the war basically her master wanted to use her as a mana battery so that he can power a stronger servant. If this cannot fly, I will adjust the background story by a bit, and made her self taught magi who accidentally awakens to her power when something traumatic happened in her childhood.

As for reinforcement, it is an honest mistake. I did not realize that it is a Western Thaumaturgy. I will remove it from her skillset, it's not really that important to her character anyway :)
