This insert is designed to be compatible with Kingdom Death Monster®, and the insert has space for a total of 1,300 standard sized cards and 440 gear cards in total. The design provides both efficient storage and improved game play. All of the trays can be utilised during the game, and they greatly aid set-up and clear-away times. The insert works together with the FS-KDM+ insert to store, in addition to the main game, many of the game's expansions.
This insert alone does not fully fill the box, and hence the game cannot be stored vertically with this insert alone. It is arranged with the tokens and dice in trays on top. On the right is a gap sized to contain the main rulebook and larger tiles. On the left is a recess for the small board and the player boards, with additional space for the larger terrain tiles from expansions.
