11Starting Bag Size2233You begin with 30 bag slots (shown in the lower portion of your inventory screen). A separate 20-slot equipment bar along the top holds your tools and weapons and does not count toward bag space. Eight expansions are available, each adding 5 slots, bringing the bag total to 70 slots.4455Because your day-to-day tools fill an entire row on their own, upgrading the bag early gives you the breathing room you need for gathering trips, quest items, and gifts.6677How to Expand Your Bag8899Open your bag (press B on PC).Below your existing slots, in the bottom-left corner, there is a button labeled "Expand". Click it.A pop-up shows the materials needed for the next expansion tier.If you have all the required materials in your inventory or nearby storage, confirm the expansion. If you are missing something, hover over the item icon to see its name and how to obtain it.10101111You do not need to visit a shop or NPC. The upgrade is built directly into the inventory screen and can be done anywhere, anytime, as long as you have the materials.12121313All Expansion Tiers14141515Each expansion adds 5 slots. The first three tiers use basic raw and refined materials that are easy to gather in the first few in-game days. From expansion 4 onward, the recipes grow significantly and demand products from multiple professions, farming outputs, animal drops, and crafting station output. This encourages diversifying across professions rather than specializing in only one.16161717TierTotal SlotsMaterials RequiredMaterial Sources1355 Softwood, 5 Stone, 5 FiberGather from trees, rocks, and shrubs.

Crafting stations automatically pull materials from both your bag and nearby storage boxes, so you do not need to carry everything in your inventory while crafting.26262727Storage BoxCapacityMaterialsUnlock RequirementStorage Box I18 slots8 SoftwoodComplete "Return to the Cabin in the Woods" tutorial quest from SolaraStorage Box II36 slots6 Softwood Plank, 3 Copper SheetApprentice Crafter rank; buy blueprint from Zerine's General StoreStorage Box III66 slots6 Hardwood Plank, 3 Iron SheetJunior Crafter rank; requires Worktable II; buy blueprint from Zerine's General Store2828Flawed Chests29293030Flawed Chests are scattered around the world and hold 32 slots (equivalent to a Storage Box II). When you open one, you can either collect the chest itself to place as storage at home, or take the contents inside (usually Coins). Keep an eye out for these while exploring, as they are a free storage upgrade early on.31313232Realm Box33333434The Realm Box is the endgame shared-inventory chest. Every Realm Box you place shares the same internal inventory, similar to an Ender Chest in other games. Items placed in one Realm Box are accessible from any other, making it invaluable for keeping supplies at your farm, the Moonlit Forest entrance, or any other frequently visited area.35353636DetailInfoUnlockIntermediate Crafter certification from ZerineBlueprint Cost7,500 Coins at Zerine's General StoreCrafting Materials5 Alloy, 3 Spirit Cube I, 5 Starflare Core, 6 Hardwood PlankCrafted AtWorkbench II3737You can also access a Realm Box directly from your inventory if you carry it in your bag. Building more than one and placing them at strategic points around the island is well worth the investment. Recommended locations include your home base, the Moonlit Forest entrance, and any area where you spend significant time gathering or processing.38383939Storage and Inventory Tips40404141You can turn in materials for Bulletin Board requests and quests directly from your storage chests. You do not need to carry those items around, which saves bag space.Gifts for NPCs are the exception. You must have those on your person.Build Storage Box II and III from Zerine's General Store to increase home storage capacity early.Keep one Storage Box near your crafting stations and another near your farm for convenience.Position storage boxes near relevant workstations: ores next to smelters, cooking ingredients next to your kitchen, seeds near your crop fields.Maintain a buffer of 5 to 10 empty bag slots before leaving your base so you have room for unexpected drops while exploring.The Realm Box eliminates the need to carry materials back and forth between locations. Build one at home and one wherever you spend the most time.Consider expansion tier 5 a priority milestone. It requires products from farming, ranching, and processing, so start raising Chickens or Ducks early for the 5 Eggs required.For expansion tiers 7 and 8, begin stockpiling Honey and Rice well in advance. These take time to accumulate (20 Honey and 20 Rice for tier 7 alone).42424343Related Articles44444545Crafting StationsOres and ResourcesToolsZerineFarmingAnimalsRealm BoxMoonlit Forest
