Enter Nihil's Oubliette is a Key item used to fight Nihil following the end of Nightwave Series 3: The Glassmaker. It can be purchased from Nightwave Offerings for 60, and can be traded between players. Note that Nightwave Offerings are rotated on a weekly basis, so this item may not be available on a succeeding week.
While in possession of the key, the player can fight Nihil again by interacting with a Nihil's Oubliette decoration installed on their Orbiter, which was obtainable from defeating Nihil during Series 3 or can now purchased from Nightwave Offerings for 60.
Succeeding in this fight will consume the key and award a Riven Mod. Additionally, after the first successful fight, a player who does not have it yet will receive a blueprint for to their Inbox (default > COMMUNICATION > INBOX). The key is not consumed in case of a mission failure, allowing for infinite practice attempts until succeeding in the fight.
