The Nightmare Clock is one of the many monster drops that can be acquired in the Frontier. They can be acquired through multiple means that include the following:
- A possible reward from the Firefly Quest.
As its description implies, it is a horrid-looking clock with two sets of two 'hands'. Two set of 'side hands' can be seen on the sides of the clock, although it is unclear what it is supposedly used for. A purple 'button' can be seen at the center of the clock, as well as a stripe stretching from one end to another of the hexagon-shaped clock. In addition, two smaller hexagonal objects can be seen behind the clock.
The Nightmare Clock does not have any apparent usages in-game, other than being sold to a selling vendor at a selling price of 40,000 gold.
