Enter Nihil's Oubliette is a one-time use Key item used to fight Nihil following the end of Nightwave Series 3: The Glassmaker. It can be purchased from Nightwave Offerings for Template:Wc, and can be traded between players.
To use the Key, the player must interact with a Nihil's Oubliette decoration installed on their Orbiter, which is obtained from defeating Nihil during Series 3 or purchased from Nightwave Offerings for Template:Wc.
Completing this fight will award the 
Vitrica to players who did not originally fight Nihil during Series 3. Continued refights will reward a Riven Mod.
