When you successfully defeat a Dominion that had defending forces,
you can plunder the defending Lord's Equipment at a certain chance.
You can't choose what you want to plunder, but obtain what the defending Lord was equipped with at the time.
Also, you can't use Peace Shield when you have Plundered Equipment.
You can obtain your Plundered Equipment after 24 hours.
※ The bigger the level difference, the lower chance you can plunder.
