Treat it as three connected panels
Harbor Drill supplies Corsair Keys and progress rewards. Buccaneer Bounty uses the keys to open chests. The Emporium spends the Pearls of Enigma you obtain. Keeping that sequence clear prevents confusing a reusable key with a shop currency that expires.
Daily routine
- Complete the free Daily Drill tasks and claim their keys before reset.
- Inspect the chest board and its refresh cost before opening.
- Compare what the next chest milestone gives with the keys required to reach it.
- Check the Emporium offer list against your kingdom progression before choosing a reward goal.
Before the shop closes
- Spend Pearls deliberately: compare the item quantity, price and limit in the current offer.
- Unused Pearls convert into resource chests at event end. That is a different rule from holding Corsair Keys.
- Check the remaining event and shop time separately.
- Consider paid Harbor Tome rewards only after checking how much task progress you will finish; the free tasks remain useful on their own.
