Dragon-sealing patch(封龍貼) is a magical item requested by XIa lai xing de liu[夏蘭荇德．流] of the Xia Lan Xing De family to contain the uncontrollable magical abilities of the children. It was created by the Weapon Management Office upon Ah gong's request. According to Xiu, these patches are used for disabling power-users with very special yet unstable abilities to prevent them from losing control and turning evil. Though the power-user's powers are sealed, they can still access them when they join with others to cast joint spells.
