In the core series games
When used from the Bag in a wild encounter, it attempts to catch the wild Pokémon. If used at night or in a cave, it has an increased catch rate modifier.
The Dusk Ball cannot be used in situations in which Poké Balls cannot be used, such as in wild battles with two or more opponents currently present or against a trial Pokémon. If used in a Trainer battle, the opposing Trainer will deflect the ball, wasting the item.
Generation IV to VI
If used at night or in a cave (excluding Mirage Caves), the Dusk Ball has a 3.5× catch rate modifier; otherwise, it has a 1× modifier.
Generation VII onward
If used at night or in a cave, the Dusk Ball has a 3× catch rate modifier; otherwise, it has a 1× modifier. If used on an Ultra Beast, the catch rate modifier is instead always set to 0.1×.
Fling fails if the user is holding a Dusk Ball.
