Big Chest Recipe Route
Unlock / Carpenter's Shop, 5,000g, Wood, and Copper Bars
Big Chest is the direct 1.6 storage upgrade: buy the recipe from Robin's Carpenter's Shop, craft it with Wood and Copper Bars, then upgrade high-traffic regular chests to 70 item slots.
Big Stone Chest Route
Unlock / Dwarf recipe, Stone Chest prerequisite, and 250 Stone
Big Stone Chest is the stone-based 70-slot upgrade. Its recipe is bought from the Dwarf after the Stone Chest recipe is unlocked through Robin's Resource Rush.
Stone Chest Prerequisite
Special Orders / Robin's Resource Rush and Stone Chest recipe
Stone Chest comes from Robin's Resource Rush, where Robin asks for a large Wood or Stone collection. Completing it unlocks the Stone Chest recipe that later gates Big Stone Chest access.
Upgrade Without Emptying
Mechanics / Replace regular or stone chests while keeping contents
Big Chest and Big Stone Chest can be used on regular or stone chests to replace them while preserving contents and dropping the old chest, making storage upgrades much less painful.
Color Coding and Layout
Layout / 20 colors, route zones, sheds, and farm work lanes
Big chests keep the color picker behavior, so storage can be organized by route: crops, fish, mining, gifts, cooking, artisan machines, Ginger Island, and request stockpiles.
Storage Resource Economy
Materials / Wood, Copper Bars, Stone, buildings, and machines
Big storage competes with buildings, machines, crafting, and farm expansion. The best route upgrades a few critical chests first, then scales into sheds and deeper material lanes.
