You can recover your Equipment by spending Gold.
The amount of Gold needed depends on the Tier and the number of Slots of the Plundered Equipment.
■ How to recover your Equipment
- [Enter the Dominion] > [Chest icon on the top left] > [Equipment Plundered] > [Recover]

Some of Gold you spent will be sent to the Lord who Plundered you.
