The Bad Dust is a 'harvestable' and a monster drop that was introduced during the Ratboy's Nightmare Update. It is one of the many collectibles that are needed by the players in order to complete the entries of the Itempedia of the Nightmare. There are many ways to acquire the Bad Dust that include but are not limited to:
- A possible drop from the Boomer.
- A possible drop from the Macabre Candelabra.
- Anywhere in the following locations:
As implied by its description, the Bad Dust is a pile of dirty, useless material from the Nightmare's zones. Other than that, nothing much can be said about its looks.
Players may trade in the Bad Dust to the Gargoyle while making a deal with the NPC, which is collectively known as the Gargoyle's Deals. However, this can only be traded in if and only the deal is available throughout the servers, as one deal can only appear each real-life day.
