With the minigame off you only need invisibility (which you learn for free from the main story) and drain mana. It was more of a simple errand than anything else, to not make it ridiculously simple. I suppose stripping Anisa made it more complicated for you.
I believe she forgives you after the foursome with her, Asara and Magda. Not sure - I haven't touched her in years. You'll have to go to China first and do Magda's request.
Thanks for the overall feedback.
