Nightmare Dungeons are difficult-level special, rare dungeons. They give out specific rewards depending on what type of dungeon it is. These dungeons have also level requirements in order to take part in and/or get dungeon token drops.
You MUST have a nightmare dungeon token in order to create a team. Nightmare dungeon tokens are rare drop rewards from regular Star Dungeons.
You only have ONE free attempt to join another player’s nightmare dungeon team. If you have a dungeon token, it does NOT use up your free attempt.
As long as you have a dungeon token, you can run a nightmare dungeon as often as you’d like. There is NO LIMIT on how many dungeon tokens you can use in a day.
The party Leader (who has the token) get will get 400% of the dungeon rewards IF they have a FULL team. A two person run yields 200%. Team mates/Solo only get 100% of the dungeon rewards–so make sure you invite some friends!
