Monster Hunter Stories 2: Wings of Ruin may revolve around the idea of adding new Monsties to your stable, but that doesn’t mean you have endless space. As you play the game and search for more monsters, you’ll need to unlock more space to keep them.
To do this, you will have to play the game until you meet a strange cat that will give you access to the Melynx Inc. store. This happens when you are still operating from the first village and it doesn’t take too long. Melynx Inc. Store sells rare but important items and trades only in bottle caps.
Bottle caps can be found in Everdens, which spreads through the game and must be prey from the chest. To find Everden, keep your eyes open for the day with a square stone entrance. The very first Everden you will find will be introduced as part of the search for the mysterious cat.
You can purchase a stable extension called “Stable Blueprints” at the Melynx Inc. store. for bottle caps, so log in often and always watch out for Everdens when exploring the game. There will be a Melynx merchant in every town and village you meet, so you can always find them easily.
