Aha, Tig clarifies me better than I am capable of clarifying myself.
I almost never go out of order when critiquing quests so this is not a full critique. But I will go more in-depth about the powers and why your eternal attack should be changed on a more general level. I know you struggled with understanding my reasoning based on the PMs we exchanged previously. I want to post it here for the benefit of other questors -- and I hope you don't mind.
Your sphere sets the focus of your powers, but then there is also a theme. For example, Ares is the senshi of smoke, and the general theme of her attacks is widespread smoke casting. I could have made her eternal attack creating a super thick bullet of smoke that she fires into the throat of an enemy to suffocate them. It would be smoke... but it would be weirdly out of sync with the theme of the rest of her powers. Does that make sense?
To me, Halley's powers go from a nursery-rhyme style superstition to a random very serious magical concept of the protective effects of salt rings. This, to me, is a disconnect. I am trying to help strengthen your concept, and because you have an odd sphere, yes, there may be some additional bending to make it fit. I would recommend you doing a theme, perhaps, of "broken" superstitions -- perhaps broken mirrors at eternal?
In the hopes of keeping Halley's powers from needlessly stretching into what could be the realm of another sphere, I encourage you to change it to a superstition that fits more with "step on a crack, break your mother's back" for the eternal level. I'm sorry if you found this confusing, but not every sphere is black-and-white and not every power set is black-and-white. I hope this helps clarify what I tried to explain before.
