How to Use “Exchange Center"
Once you have collected enough, visit the Exchanger
NPCs (Ishtal in Braiken Castle or Stacy in Loa Castle) to trade your collected items
for unique items.
Select an instanced dungeon on the NPC's dialogue
and choose your preferred reward from the list.
Click the "OK" button to select your item, which
will be placed automatically in your inventory. The required amount of exchange
items will be removed at the same time.
If you don't have enough exchange items to trade
for a specific item option, the trade will not be allowed.
