I agree, like if that were me, I would've excitedly shown my stronger abilities to the mentor which would've made him be like "ohh no no no". Because bruh she already showed off her potions to help others and did the whole viewing crystal thing which now people know about, I imagine she would've been excited or uncertain at least about the limits of her spirit powers to reveal it to her mentor who would know a thing or two about it
Wasn’t there an issue with spirit users where the more they use that power, the shorter their life span gets?
Or since the art chanted, the plot does too?
