Preserve boss Ergo for Alidoro’s exchange

Keep a boss Ergo available until you decide between its special equipment and ordinary currency value.

PC / Global, base game with Overture expansion
WHERE & HOW TO FARM

Where to farm

Alidoro’s special equipment exchange at Hotel Krat or his available location after his service is unlocked.

Boss Ergo has an opportunity cost: consuming it as ordinary currency removes the option to exchange it for special equipment. When Alidoro’s service is available, compare the special weapon and amulet options before choosing. This does not create more boss Ergo; it helps turn a one-time boss reward into the item that best supports your build.

GET STARTED

How to farm

Before you go

  • Defeat a boss that awards a special Ergo item.
  • Retain that Ergo instead of consuming it for ordinary currency.
  • Reach Alidoro and unlock his exchange service.
  1. After defeating a boss, check your inventory for its special Ergo reward.
  2. Do not use the item if you may want the weapon or amulet it can unlock.
  3. Reach Alidoro once his exchange service becomes available.
  4. Open the exchange options for the specific boss Ergo you retained.
  5. Compare the offered special weapon and amulet against your current equipment and intended build.
  6. Choose one item and complete the exchange, or leave the Ergo unused if you need more time to decide.
  7. Equip the selected item and check its upgrade path before spending Covenant Moonstones.

Farming tips

  • Consider whether the boss weapon’s moveset or the amulet’s effect fills a real need in your setup.
  • Keep in mind that saving the Ergo delays its use as ordinary currency; make the choice before an urgent level-up if possible.

Repeat, collect and use

Each boss Ergo is a limited reward for that playthrough and normally supports a choice from its exchange options. It is not a repeatable farm.

Common mistakes

  • Do not consume boss Ergo for ordinary Ergo before checking Alidoro’s options.
  • Do not assume the exchange provides both rewards; compare and choose the offered item you want.
  • Do not spend special weapon stones before checking whether the exchanged weapon uses them.

When to stop or switch

Stop once you have chosen and exchanged the boss Ergo, or keep it safely unused until one option is clearly more valuable.
