WHERE & HOW TO FARM
Where to farm
Ace’s shop in Ward 13; use Lumenite at McCabe or the relevant upgrade service.
When a recipe is blocked by a small Lumenite shortfall, check Ace’s materials shop in Ward 13 before committing to another world run. Her inventory may offer Lumenite for Scrap, but availability is not a guaranteed fixed supply. Use the displayed recipe cost and the actual shop listing to decide whether a purchase is worthwhile; elite enemies remain a repeatable alternative source.
Know the Lumenite cost of the item or upgrade you plan to complete.
Check the intended McCabe recipe or upgrade cost and note the Lumenite shortfall.
Speak to Ace and inspect the current shop inventory.
If Lumenite is listed, review the Scrap price and purchase only what supports the immediate goal.
Return to the relevant Ward 13 crafting or upgrade service.
Confirm that the material total now covers the displayed cost.
Complete the craft or upgrade if all other materials are ready.
If Ace has no Lumenite, return to exploration and collect drops from elite enemies.
Farming tips
Shop inventory can vary; do not budget as if Lumenite is always for sale.
Compare Scrap’s competing upgrade uses before buying materials.
Repeat, collect and use
The shop can be checked again, but each purchase depends on stock and Scrap. For repeatable gathering, continue defeating elites and collecting their variable drops.
Common mistakes
Planning around an assumed listing: inspect Ace’s actual stock first.
Buying before checking the recipe: determine the exact shortage at McCabe or Rigs.
Spending Scrap needed for another priority: compare the purchase with your weapon and armor upgrades.
When to stop or switch
Stop buying once the planned recipe is covered or Ace has no available stock; switch to elite encounters for further Lumenite.
