Bad Luck, also known as Unluck, is a status effect that decreases the chance of the player getting high-quality loot, contrary to Luck.


Bad Luck subtracts the effect level from the attribute generic.luck, making loot table entries with a high quality score less likely, and entries with negative quality more likely. It also makes the chance of bonus_rolls occurring less likely. Fishing is the only mechanism that uses quality. The new weight of each entry is floor(base_weight + quality × generic.luck). Negative levels increase luck, similar to status effect Luck.


Bad Luck cannot be obtained except by the Effect command.

The effect was initially purely experimental and was intended to be removed later (hence its unobtainability in survival), but was ultimately kept in the game due to usage by mapmakers.[1]
