Neplunker Zero is an optional dungeon in Megadimension Neptunia VII found by scouting in the Zero Dimension. It costs 100 credits to build a route to the dungeon. This dungeon requires the ability to break all destructible items to complete. In addition, it is recommended to complete this dungeon in a New Game + due to the flag items that make the dungeon easier. Completing the dungeon by making it to the exclamation mark rewards the player with the strongest non-DLC armor, Celestia Bangle.
