Pro tip by Professor WillowIf you are unable to get Yamper with its best moveset, we recommend to use Spark/Thunder. You will lose around 4.9% DPS and TDO, which makes these moves a viable alternative to Yamper's strongest moveset (Bite/Thunder).

        Mega Pokémon that boost Yamper


        A list of Mega Pokémon that boost Yamper's Electric-type moves, Candy, and Candy XL from catching Yamper.

        Pokédex informationMore information

These do not stack with each other. Additionally, High and Max Level Mega-Evolved Pokémon grant an increased chance to obtain Candy XL when catching a Pokémon that shares a type with it.

        Note on Primal Kyogre, Primal Groudon, and Mega Rayquaza
        • Primal Kyogre boosts Water-, Electric- and Bug-type attacks and Pokémon.
        • Primal Groudon boosts Fire-, Grass- and Ground-type attacks and Pokémon.
        • Mega Rayquaza boosts Flying-, Dragon- and Psychic-type attacks and Pokémon.

                Catch probability with multiple throws

                In order to help Trainers understand their overall odds when catching Yamper, we enable the functionality to showing the total chance to catch it depending on the number of available throws. We calculate this chance as if you repeated the same throw N-number of times.

                To activate this functionality, change the number of Number of throws to a value greater than 1. The Number of throws option is available in the configuration options above the chart

                Catch rate formula

                Pokémon GO catch rate formula can be expressed as follows:

                • CATCH_MULTIPLIERS = ball * curve * berry * throwType * (type1Medal + type2Medal / 2)
                • CATCH_RATE = 1 - Math.pow(1 - baseCatchRate / (2 * cpm), CATCH_MULTIPLIERS)

                There are different multipliers that come into play when calculating catch rate.

                Curved throws are more effective than regular throws, stronger types of Poké Ball have a higher catch rate, and using a Razz Berry or a Golden Razz Berry also improves your chances.
