During the new solstice event I have purchased all solstice armor. However, they first piece I purchased was the lustrous chest armor. I infused it automatically with a different chest piece. Now I realized there chest piece is no longer dropping for me. To complete and guild the flame keeper seal I need all 5 piece of lustrous armor equipped whiles doing portal activites. How can I get another lustrous chest piece when it won't literally drop after infusing it with an different chest armor?
