Fairly early on in Monster Hunter Stories 2: Wings of Ruin, you'll be introduced to the mysterious Felyne merchant that runs the Melynx Inc. store. This special shop sells a range of highly useful items, such as stable upgrades, item combination recipes, armor, weapons, and cosmetic gear for your character, Ena, and Navirou.
However, to purchase any of these sought-after items, you'll need to collect Bottle Caps first. Bottle Caps can be earned from completing certain subquests, as well as being found within treasure chests in Everdens that are scattered throughout the world. You can only find Bottle Caps once per Everden, so you'll likely want to find all Everdens to get enough caps to get everything you want. In the post-game content, you can find Bottle Caps from treasure chests in High Rank Dens and can also receive them from multiplayer quests and battles. We have the location of each Everden listed right here.
