Genshin Impact’s Golden Apple Archipelago will have Phantasmal Conches scattered around. This is similar to the Echoing Conches required to obtain Barbara’s “Summertime Sparkle” outfit from last year’s event. These Phantasmal Conches can show players projections of the past. Collecting the necessary number of Phantasmal Conches will reward players Fischl’s outfit, “Ein Immernachtstraum” for free, along with Primogems, Mora, and Level-Up Materials.
