If she was not practicing her acting during her free time and watching movies to use as reference and learning materials, then she was busy practicing something else.
Practicing her usage of spells was a regular thing for her that she made time for every day, while other things were done whenever there was enough time to do so.
If she was not doing either of those things, then she would either be resting, practicing drawing inscriptions or learning how to use the various forms shown in other videos, which were related to the use of certain types of weapons.
While she did learn how to use a wider variety of weapons, there were still some that she had more experience with using and that she thought suited her preferences more.
Perhaps it was the influence from her past pursuing acrobatics and gymnastics that had helped toward such a familiarity and preference, but she tended to prefer things that she was more comfortable with, like staffs or something similar.
