Running out of room for gear and materials in Final Fantasy 16? Here’s how to expand your inventory space, carry more loot, and keep Clive fully stocked for the toughest battles on PlayStation.
As you’re playing Final Fantasy 16, you’ll be bombarded with the message: “Insufficient inventory space. Potion used.” With a maximum of four potions and three high potions available to use in the beginning of the game, you’ll start to wonder when you can finally hold onto more potions. Luckily, you can increase your potion capacity by completing the side quests “Weird Science” and “Even Weirder Science,” but it will take some time to reach these quests.
How to increase your inventory size in Final Fantasy 16
Complete the Weird Science side quest in the Hideaway after the Letting Off Steam III main quest to receive the Treated Potion Satchel, which boosts potion capacity from four to six potions, three to four high potions, and two to three each of strength and stoneskin tonics. Progress further to unlock Even Weirder Science from the same engineer Owain, where clearing three Fallen Ruins grants the Expanded Potion Satchel for maximum capacity of eight potions, five high potions, and four each of tonics. These upgrades apply only to consumables and complete inventory expansion in the game.
In Final Fantasy 16, you can increase the amount of potions you can carry by completing the side quests “Weird Science” and “Even Weirder Science.”

Where to start the Weird Science quest in Final Fantasy 16
Start the “Weird Science” side quest in Cid’s Hideaway. It becomes available after completing the “Letting Off Steam III” sub-quest during the main quest “Out of the Shadow.” Speak to Owain (or Mid) to begin it.
Exact Location
Head to Mid’s Dungeon in The Hideaway. This area is on the bottom floor near the smithy section. Look for Owain, the engineer, in this workshop-like zone.
Quest Prerequisites
Progress through the main story until “Out of the Shadow.” Finish all three parts of “Letting Off Steam” first, then check the quest board or speak to Mid to unlock access to Owain.
How to find the Bomb King location quickly
Fast travel to The Dragon’s Aery obelisk in Sanbreque for the quickest access to the Bomb King.
Directions from Obelisk
Head south from the fast travel point into The Crock area, east of The Dragon’s Aery and north of The Imperial Chase. Follow a narrow path through the woods past stone walls and a broken metal gate, then through a fenced section until reaching a dead-end circular arena with the Bomb King.
Prerequisites
This hunt activates only after starting the Weird Science side quest from Owain in Cid’s Hideaway. Check the Hunt Board with Nektar to track it.
