How to increase inventory space in Final Fantasy 16

While you play FinalFantasy 16, you will be bombarded with the message: “Insufficient inventory space. Potion used.’ With a maximum of four potions and three high potions available to use early in the game, you’ll start to wonder when you’ll finally be able to hold more potions. Fortunately, you can increase your potion capacity by completing the side mission”Crazy science”, but it will take some time to reach this quest.

We’ve currently upgraded our inventory room once through the “Weird Science” side quest and we know you can upgrade your pouch a second time thanks to the “With Two Ds” trophy, but we haven’t done this yet in our game. We’ll update this post with more information once we figure out how to upgrade your inventory a second time.
