Just like Mt. Travail, this dungeon has weather conditions on certain floors that will always occur. The weather is cloudy on floors 3, 4, and 10, sunny on floors 8, 14, and D5, foggy on floors 12, D1, and D2, rainy on floor D9, while in all other floors the weather is clear. There is a high chance of Monster Houses, especially on floor 15.
There is a locked room on the ninth floor of Deep Spacial Rift which contains a treasure box.
Subsequent visits will not be permitted until the player defeats Darkrai at the bottom of Dark Crater. Pokémon in the dungeon will then be recruitable, including Palkia who automatically joins the team upon defeat. Interestingly, Drowzee, Sableye and Dusknoir, all primary antagonists in the storyline, can be recruited here.
