The Data is 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. The Data can only be obtained from the Data Mites as a possible drop from the mob.
In appearance, the Data is simply the physical form of corrupted data and what appears to be a green 'circuit board' at the very tip of the corrupted data.
The Data does not have any usages in-game that will benefit the players, other than to be sold to a selling vendor at a selling price of 4,000 gold.
- The Data is one of the few collectibles that cannot be obtained from any other mobs, other than the main mob itself (Data Mites).
