There are really 2 choices right now to upgrade: upgrade your Weathered Daystar with turn 7/9 Oil of Time to Daystar and get another Weathered Daystar (they're not unique to each other) or get the HA ring. Maybe Ramuh will have new i100 accessories but who knows. Besides the noct ring for vitality (you don't really need vit in anything below turn 9, even turn 9 is kinda meh) which I see it as a waste cause myth ring will be viable alternative, the other rings bring you nothing.
