Mystery Gate

Mystery gates are a new addition to Disgaea 2's Item World and onwards. These gates will spawn on any floor in the item world except for boss stages. When any character moves onto a Mystery Gate tile, the party will immediately enter the Mystery Room. The current floor will not be considered cleared, but after exiting the Mystery Room, the party will be back on the same floor number, with the floor layout randomized again.

Disgaea 2 Mystery Rooms
Upon entering the Mystery Room, the player can access the warehouse and items and change the party's equipment freely. To leave, talk to the Gatekeeper Ghost.


 * Orc Pirates: Get random pirate information and item chests which contain rare items.


 * Heavy Knight: A lone Knight that always has two legendary Chests and gives a tip to the player about the Land of Carnage.


 * Dragon: Fight a Dragon named Juzeppe. Has 1 to 3 chests available. Be careful not to hit the level 1000 Room exit NPC, otherwise it'll attack (great for really high levels, though)


 * Chests: Free chests for the taking. Usually 3 with one legendary surrounded by two rare chests.


 * Item Shop: A Marionette named Cage runs the Rosenqueen Item World Branch. You cannot annoy them into fighting you.


 * Cellphone Shop: A Prinny named Yusak offers Cellphones for purchase. Talking to him too much will annoy him into attacking you.


 * Mana store: A Blue Skull named Muishkin sells mana potions. You cannot annoy him into fighting you.


 * Rosenqueen Dojo: A Sinner Named Selgio sells Weapon Scrolls.


 * Bribery Specialists: A Zombie named Samed lets you buy items for bribing Senators. You cannot annoy him into fighting you.


 * Hospital: An Alraune named Momolin who will heal the party just like she does on an Innocent Town.


 * Rip off Bar: A room managed by Bolianne, a Succubus and 3 other female monsters. An Elbacky, Succubus, & Alraune with randomly generated names. Your Bonus Gauge will be increased at random just like the Bill in the Dark Assembly but at the cost of halving every unit's life in the base panel including Adell or by paying 10000 Hell. They will also attack if you talk to them with Bolianne saying, "We don't like the persistent type like you. I'll have to teach you a lesson with the rough treatment" before the fight.


 * Department Store: An Archer named Lime and the Item, Bribery, Mana and Cellphone Shops mentioned above. Each shop can only be entered once per visit. Talk to the store owner (or the Archer) too many times, and they will attack.


 * Ambush Room: Seven monsters where one is the leader of the pack alone and the other six are set in teams of two. Complete in two turns to gain 3 levels on the item. The seven monsters are always the same type, and can be of any class including Prinnies but on that specific floor they do not explode when thrown. Also when entering the monster room there is no Dimensional Guide, meaning you must fight the monsters in order to advance. After starting a battle, Mr. Gency's Exit can be used.


 * Fortune Teller: Get a fortune from a Geomancer named Zuar. Be careful, as it can be either a gain or loss of levels. (-10, -3, 3, or 10 levels). He can fight you if you talk too much to him and say; "I told you to come back another day! Your new fortune is...divine punishment!!" before the fight.


 * Lost Resident: You'll find a Collector, a unique resident that will want to move into your item. If you allow the Collector to move in, it will be a subdued at Level 1, which will immediately increase the item's rarity by the same number as its level.

Unique to Dark Hero Days

 * Mao's Laboratory/Blacksmith: Where monsters can be upgraded from Magichange 1 to Magichange 2.


 * Paint Shop: A Holy Dragon will offer one free color change for any non-unique character in your party. After the first encounter, they can appear in the base town for a rather expensive re-paint job after passing a bill in the Dark Assembly.


 * Music Store: The Music shop NPC from the hub will let you purchase/change Item world tunes. This makes it more challenging from Afternoon of Darkness to obtain music, where the NPC was always selling music in the hub. Prices for music are also a lot more varied in price, from 100k HL up to 1,000,000,000 HL.with 100k, 500k and other prices being offered. This is also where you purchase music from DLC characters as well.


 * Fortune Teller: In DHD, the -10 result has been removed, and defeating him gives an additional +3 bonus levels.

Disgaea 3 Mystery Rooms
Disgaea 3: Absence of Justice, in addition to several of the above events, has a few new rooms of its own.


 * Scalper: Sells Illegal Tickets for unlocking the X-Dimension Maps. There are two Scalpers, one on Floors 1-49, and one on Floors 51-99. The Illegal Tickets are very expensive, some costing over 10 billion HL so it is recommended that the player save up for them first.

 * Treasure Room: A room filled with many Treasures located on top of platforms with varying heights.

Disgaea D2 Mystery Islands
Disgaea D2: A Brighter Darkness changes how Mystery Rooms appear, now referred to as "Mystery Islands". Unlike previous games, Mystery Gates do not spawn on an Item World stage. Instead, there is chance that the player will automatically enter a Mystery Island whenever a stage is skipped or cleared. A maximum of 2 Mystery Islands can appear in every 10 floors.

List of Mystery Islands/Rooms introduced in Disgaea D2: A Brighter Darkness:


 * Rock-Paper-Scissors Master: A Female Brawler who challenges the player to a game of Rock-Paper-Scissors. If the player wins, he or she can get a level boost to the item or an item such as a sardine.


 * Transfer Shop: An island with a Succubus who asks the player if he or she wants to skip a certain amount of floors. The player can skip 5 or 10 floors, but he or she has to pay to skip floors.


 * 'Innocent Shop: An island where a Thief sells rare Innocents such as Guardians. The player can only purchase one Innocent from the shop per visit.


 * Innocent Plaza: An island where the player can interact with the Innocents inside the Item. Talking to the Innocent increases its value greatly.


 * Item Boss Island: An island where an Item General/King/God gives a free 5%/10%/20% boost to the base stats of the player's item.
