For the effect that causes raids, see Bad Omen.
This feature is exclusive to Java Edition.
Bad Luck, also known as Unluck, is a status effect that decreases the chance of the player getting high-quality loot, contrary to Luck.
Effect[]
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.
Causes[]
Bad Luck cannot be obtained except by the Effect command.
