On each level of the Tower of Barbs, there is a Stamp Machine in certain floors, as part of the Stamp Rally. Using the machine activates a small rhythm-based minigame, where you must hit up to 5 notes with the right timing. Completing this will grant the player a Stamp in the My Collection > Stamp Rally page of their Underworld Rolodex*. Defeating each of the four Dons will also grant a Stamp. Upon completing groups of stamps (e.g. stamps 1-5 or 6-10), Uncle Death will give the player a reward. Getting all the Stamps in floors 1-40 will reward the player with the Grim Reaper's Scythe (Silver), and getting all the Stamps with a PERFECT will reward the Grim Reaper's Scythe (Gold).
After defeating Taro Gunkanyama, the Stamp Mount Exchange in the Waiting Room may be used to reset groups of stamps within each faction area.
* Getting a MISS will not show a stamp visually, but still counts towards the completion of the Stamp Rally.

Battle to the Top (Floors 41-50)
Due to how the floors in the 40s are random, there are no specific Stamp Machine locations. However, the floors themselves are based on individual floors from below 40F in the Tower. This means that they use the same tilesets as the floors listed above, and the Stamp Machines will spawn in similar locations. Typically they will only spawn in one spot per tileset, though some may appear in more than one location.
