Version-aware guidance
What changed recently
September 4 added Darkmoon Fair, Ivory Tower and Old Vinery and changed furniture costs and navigation. September 18 added a separate gear-upgrade system at the Blasphemous Anvil; shop expansion and gear upgrades now need distinct budgets.
Read the dated update timelineName the constraint before spending
Write one sentence describing what is blocking progress: runs end too early, useful stock cannot be displayed, customers move poorly, or cash accumulates too slowly. An upgrade earns priority when it directly changes that sentence.
Compare the live Darkmoon Fair, Ivory Tower and Old Vinery options with your current property. More room must be furnished and kept navigable under the new obstacle system. Record the displayed purchase and furnishing costs; these notes do not supply a verified price list or an optimal property order.
Protect operational continuity
Keep enough liquid cash, usable equipment, and ordinary stock to resume the loop after purchase. An upgrade that leaves the shop beautiful but the next expedition unfunded is a temporary regression.
Before a structural change, record important inventory and preserve a save copy. The August save fixes and Ver. 1.1.3 Construction Chest safety net supersede blanket claims that upgrading wipes a shop. If older furniture appears missing, check the Construction Chest and the specific recovery guide before changing files.
Measure one upgrade cycle
Enter the full upgrade cost and your observed average session profit in the Shop Upgrade ROI Planner. Treat a projected profit lift as an assumption, then compare actual sessions after purchase. Keep prices and stock comparable; otherwise a property change and a pricing change cannot be separated.
If the outcome does not improve, diagnose placement and workflow before stacking another expense on top. Bottleneck-first progression is a feedback loop, not a fixed sequence copied from another save.
Outdated advice to avoid
A launch property list or furniture-cost table is incomplete. Historical shop-loss reports should be read alongside the later save and Construction Chest fixes, rather than as proof that all upgrades still lose stock.
Frequently asked
Questions about fell and sell upgrades
What is the best first upgrade?
No universal order is verified; choose the smallest upgrade that removes the constraint currently stopping profitable runs or sales.
How do I upgrade more safely?
Clear valuable rack contents, record important inventory, and copy the save folder before structural upgrades, then verify everything immediately afterward.
How was this guide verified?
Reviewed September 19, 2026 against the linked official Steam announcements. Ver. 1.4.3 is the named patch baseline; the September 18 public Dungeon Update is distinguished wherever it changes earlier advice. Older developer replies and community reports retain their original dates and labels.
