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