WHERE & HOW TO FARM
Where to farm
Fillmore for weapons and Mira or Meri for armor in Sacrament.
Prepare for a Plagued zone by checking your equipment and upgrading the pieces that matter to your chosen build. Fillmore handles weapon upgrades, while Mira or Meri handle armor upgrades in Sacrament. Their interfaces display the current costs and resulting changes, so use those details instead of relying on remembered prices.
Have the materials displayed for your intended upgrade.
Choose the equipment you plan to carry into the next difficult route.
Inspect your current weapon and armor and identify the piece limiting your next run.
Visit Fillmore with the weapon you want upgraded and review the interface’s material cost and stat change.
Confirm the upgrade only if it supports your planned build and you have the displayed materials.
Visit Mira or Meri for armor upgrades and compare the available improvement.
Return to your inventory and equip the upgraded pieces you intend to use.
Carry remaining materials into the next run only if another planned upgrade needs them.
Farming tips
Upgrade the gear you will actually use; an unused item can absorb resources without helping the planned route.
Use the current menu for costs and effects because those values can change with updates.
Repeat, collect and use
Repeat whenever you gather enough materials for a worthwhile equipment improvement. Each upgrade spends its shown materials; this is not a resource farm that resets.
Common mistakes
Assuming a fixed cost: read the smith’s current interface before spending.
Upgrading every item indiscriminately: focus on chosen equipment for the next route.
Visiting the wrong smith: Fillmore handles weapons; Mira or Meri handle armor.
When to stop or switch
Stop when the weapon and armor you plan to use are adequate for your next target or when the displayed cost exceeds the materials you want to spend.
