Danjon Danjon no Mi

Introduction
The Danjon Danjon no Mi is a paramecia type devil fruit that allows the user to surround themselves with a huge labyrinthine fortress or "dungeon" and fill it with traps and monsters, thus providing them with imediate defensive power.

Usage
When the user activates this fruit power, a seemingly small building imediately forms around them, depositing them into the interior. While the outside of this building is quite small, the inside can expand seemingly indefinately. The user can control the layout of the building's interior, as well as the number, design, and contents of all of the rooms. Adding more rooms to the interior has a negligeable effect on the exterior, invariably resulting in the inside of the dungeon being bigger than the outside. Rooms can be filled with just about any trap or defense mechanism the user can design, so long as it is consistant with the rest of the dungeon. They can also create creatures that inhabit the rooms and attack intruders, providing further defense. Nothing that is created inside the dungeon can leave it, and if forced to will dissappear. If the user themself leaves or is defeated while inside it, the dungeon will begin to collapse and fall apart, and it's mechanisms will ultimately cease to function unless they are reinforced or repaired by outside inteference. The user can also dismiss their dungeon at any time, depositing anything that entered it back into the world at the place where it was.

Strengths
The user of this fruit is able to instantly conjor a shelter for themselves and their allies, no matter where they are in the world, and use it to provide an excellent defense against attackers. Their dungeon gives them unlimited access to terrain they know and have advantage on, while allowing them to stack the odds against any attacking opponents. As a result, it is very hard to force a direct fight with the user, and can allow opponents to be bested with little more than creatively applied traps and defenses.

Weaknesses
The Dungeon is almost impossible to use offensively. While it can provide a battlefield of the user's choosing, it has no method for forcing opponents to enter or fight within it, and nor does it provide any means of attacking outside. Additionally, while the user is protected within the dungeon, damage and attacks from outside can break through the outer shell, damaging the interior, and by the same token it is possible for attackers to skip entire sections of the maze by breaking in through the walls instead of going through the entrances. This makes it possible for a particularly powerful attacker to bypass the dungeon defense entirely, attacking the user from afar before they can use any of their defenses. The user also suffers from standard Devil Fruit weaknesses.
