Great observation young anakin
i dont think the priests did something (cuz the nice one, her teach, got the same reaction) so probs is cuz dark is opposite of light magic
Yes, I agree... but why did the priest make such a sinister face while watching her suffer?
The priest did something to Leslie.
Remember that leslie didn't had the problem with divine power when priests (early in the story) and Konrad healed her (chap34). it only occured in the trial.
I think the reason she got shocked is cause she has black magic in her or the priests did something to her
