I took Adelia's quiz in one reset, and failed it on the 5th question (I believe). A reset or two later, I was able to do this quest again. Based on her dialogue, I would think this quest is one-shot per character.

Puzzling. Does this problem occur when failing at other questions?

The quest is intended to be one-shot per character, for reference.

Also on the quiz, she says the final question is the fifth, but its the sixth.

Fixed.

This should be fixed.
