How to Use Kachua’s Secret Key
- Obtain Kachua’s Secret Key (Item ID 23919) through Mega Booster.
- Double-click the key in your inventory to summon the Secret Box on eligible maps.
- Talk to the box and choose Open 1 Key or Open 10 Keys.
- Confirm to receive 1 random reward + 1 guaranteed Kachua’s Mileage Coupon per successful opening.
Please spare plenty of empty inventory slots and have enough available weight capacity before opening keys. For 10-key openings, 15 free slots is a suggested precaution, not a guarantee. Insufficient space can prevent rewards from being added. Check your inventory before spending keys!

✨ Sky Rune Crown Enchanting & Set Combinations
Sky Rune Crowns use Enchant Group 165. The newly supported crowns are listed below, alongside their corresponding Sky weapons. Sky weapons are not enchant targets in Crown Group 165.
The nine newly added job sets below are included in the 97-reward Kachua pool. Each item has a 0.25% drop chance and is awarded at Grade C.
Using a matching crown and weapon can grant combination bonuses. Some higher-grade combination effects require Grade A equipment and a combined refinement of +24; Grade C equipment does not automatically unlock those conditions.
