Effect
A Ball for nighttime or caves.
Dusk Ball has a 3x catch rate multiplier when used at night, evening, or inside caves! During the day in non-cave areas though - it's just a regular Poké Ball.
This is one of the best balls for general use in caves as they are common and nighttime playing is ... pretty easy to time. Stock up on these and use them whenever the conditions are right. Great for cave-dwelling legendaries or any nighttime catching session.
