In Pokemon Legends Arceus, you can find Spiritomb Wisps in the form of collectibles for a request from a girl named Vessa, and these wisps are scattered throughout the Hisui region. To begin searching for them, you must first complete Mission #6, Summoned by Commander Kamado. Afterwards, you will be approached by Vessa to begin the request; Eerie Apparitions in the Night.
Pokemon Legends Arceus Spiritomb Wisp Map Locations
The Wisps are strewn about all over the Hisui Region and can be challenging to find on your own. However, searching at night can make spotting these wisps much easier, as they let off a bright purple glow in the darkness. So we recommend waiting until nighttime before searching- of course, you can still search in the daytime as well. Below will be pictures of the main areas marking the locations of each Wisp.
