- - In-game description
Purple Ring is a rare barrier that grants extra DFP if other players in the vicinity are also wearing a Purple Ring. For each other player within 5 meters wearing a Purple Ring, +50 DFP will be granted. This means that if all four players in a party are wearing Purple Rings within 5 meters of each other, each player will gain 150 DFP.
Purple Ring is obtainable in the quest Towards the Future after earning an SS-Rank rating with the maximum amount of kills possible on Very Hard or Ultimate difficulty.
