Viper Temple-Waschi Falls: Revived Coral Ring (Only)
Dark Temple-Little Monster Falling: Carrapo Blessing Ring (Attachment 2)
Sunwell Heights-Monster Falling: Ring of Harmony (2)- Don't miss it as long as you see it!
Personally, it is not recommended to take the all-around ring (Sunwell Heights-Muru/Entropy Magic Drop) for two reasons:
1. Compared with treatment, highly effective, energetic or blue-returning patients are preferred.
2. Unless no one wants it or you have become an excellent exporter in the team, it is really meaningless to compete with other DPS occupations.
