Worth knowing
Combine an Ultra Ball with an accurate curveball and an appropriate berry on a catch you particularly want. A higher modifier is not a guaranteed capture.
Ordinary bag balls cannot replace the allotted Premier Balls in a raid bonus encounter.
What the catch multiplier actually means
The multiplier changes the exponent in the catch formula; it does not simply multiply the final percentage. Holding every other factor constant, a 20% Poké Ball chance becomes about 28.4% with a Great Ball and 36% with an Ultra Ball. These are illustrative calculations, not a prediction for every encounter.
Combine the ball with your throw and berry
Ball quality, a catch-enhancing berry, throw accuracy, curveballs, medals, and certain encounter effects all contribute to the catch formula. A curveball contributes a 1.7× throw factor, while a smaller successful target circle improves the accuracy factor.
As an illustrative comparison, suppose a plain Poké Ball throw has a 20% chance and all other conditions stay fixed. An Ultra Ball gives 36%; adding a Golden Razz Berry gives about 67.2%; adding a curveball as well gives about 85.0%. These numbers come from 1 − (1 − 0.20)^m with combined factors of 2, 5, and 8.5.
The calculation assumes the ball actually connects. Spending a stronger ball does not compensate for repeatedly hitting during the Pokémon’s attack animation. Reliable throws remain part of the resource decision.
