Starting capacity
Enough for the opening route, but tight once fishing, mining and quest items overlap.
INVENTORY
Add ten slots when your route keeps ending early
You start with 20 slots. Sabrina’s Webb of Wonders shop sells the first +10 slot upgrade for 2,000G.
Quick answer
Visit Sabrina, open the shop’s inventory/bag tab, buy the 2,000G upgrade, and use 10-plank storage crates for items you do not need to carry.
INVENTORY
Bag upgrade path
First upgrade
Adds 10 slots at Webb of Wonders. High value when full inventory repeatedly ends your route.
Later upgrade
Another +10 slots is reported in launch guides; availability may depend on progression, so verify the shop panel.
INVENTORY
Use carried space and storage differently
- Carry tools, active quest items, food and route-specific supplies.
- Store seasonal seeds, rare materials and collection backups at home.
- A storage crate costs 10 Wooden Planks.
- Keep one clearly named crate for quest / rare items so they are not accidentally sold.
INVENTORY
When the 2,000G is worth it
Buy the first bag upgrade before the barn if full slots are causing lost fish, abandoned mine runs or repeated trips home. Delay it when your inventory is mostly clutter that belongs in a storage crate.
