Bank slots, Shop unlock and upgrade costs

The Shop opens after selling items for a total of 250 GP. Later, bank expansions are individual Shop purchases tied to skills. Their purchase limits prevent buying the same entry repeatedly.

Expansion costs

Skill milestone	Expansion	GP per purchase
Level 20	+20 slots	5,000
Level 50	+25 slots	25,000

Check each skill’s entry in Bank Capacity Upgrades. Reaching Mining 20, for example, unlocks its own +20 purchase; it does not buy that capacity automatically. A second eligible skill offers a different purchase.

Two level-20 purchases add 40 slots for 10,000 GP. One level-50 purchase adds 25 slots for 25,000 GP. That is 250 GP versus 1,000 GP per added slot, but the cheaper comparison requires a second qualifying skill and an unbought entry. It does not make training that skill free.

Reserve stacks for the next recipe

An arrow chain can hold logs, shafts, feathers, headless arrows, arrowtips and finished ammunition. Those are separate materials even when their quantities are small. Selling the only required intermediate can create another gathering or production detour.

Prioritize space for the selected activity’s possible outputs and ingredients. Some Fishing and Mining actions have side drops, so a single main product does not imply one output stack.

Full-bank behavior depends on the system

Ordinary Farming leaves a blocked mature crop ready to harvest. The Grain Mill uses a separate ingredient inventory and sends products to the bank. Check each system’s input and output space rather than treating all storage as one inventory.

If a custom sell quantity behaves like All or All but One, check the version at the top of the game. Demo 0.11.4 fixes that toggle interaction and a separate bulk-selection state problem. Review the selected quantity before confirming the sale.
