How to get and use Sparkly Treasure in Monster Hunter Wilds
You can obtain Sparkly Treasure either from Scarlet Forest’s Weathered Treasures or Plumpeach’s Material Retrieval. Both methods are time-consuming and need a good deal of patience, as the drops are entirely random. I had better luck with Plumpeach’s Material Retrieval; the item showed up in Wudwud’s Collectibles. To use this method, you first need to unlock Scarlet Forest’s Farm, which requires reaching High-Rank status and finishing the Make Fluffy Dealings side quest.
