1. What is 'Expedition'?
This system automatically produces Gold over time when you deploy cards into slots. 
Once the Expedition is complete, you can claim the produced Gold along with bonus rewards all at once. 
(Time progresses regardless of whether you are online or offline.)

2. Card Types
- You can deploy cards to a maximum of 5 Expedition Areas. The required Card 'Type' for each area is determined randomly.
- There are 16 Card Types in total, and a single card can possess multiple types simultaneously.
- The types that appear and their frequency vary depending on the Grade.

3. Card Level & Gold Production
- Gold Production is determined solely by the Card Level.
- The higher the Card Level, the more Gold is produced per hour.
- Please refer to the table below for Gold Production by Card Level.

4. Bonus Rewards & Grand Success
- Upon completing an Expedition, you can obtain bonus rewards such as Cards and Chests along with the accumulated Gold.
- Bonus rewards are determined randomly and can be checked before starting the Expedition.
- Upon completion, a 'Grand Success' may occur with a certain probability.
- On a Grand Success, the Bonus Rewards acquired are doubled.
- The Grand Success Rate increases based on the deployed Card's Level. Please refer to the table below for rates by level.
- There are minimum and maximum limits to the Grand Success Rate.

5. Other Notes
- If you cancel the Expedition before completion, you will only receive the Gold accumulated up to that point, without any bonus rewards.
- A single card cannot be deployed to multiple Expedition Areas simultaneously.
