Dungeon Backgrounds are used by the game instead of ordinary tilesets to render full background images in boss fights. As such, they are always used on floors that also have a Fixed Room attached, whose layout matches the background's apparent collision. Since boss fights often also have cutscenes, a copy of the dungeon background often also exists as a Map Background.

Dungeon backgrounds are very limited in their dimensions and only have one layer. They can not have animated chunks but they can have animated palettes.

Floors with backgrounds have no tilesets. Walls, water and water will be transparent (and are expected to be visible in the background image itself). Special tiles, such as traps, will render as corrupted images.
