Idk why you dont bring a masterball is not hard to win one just do pvp you will win 10 pvp easy for sure

I dont know what u have done their. Maybe it wasnt at 1hp or not even sleeping but the only pokemon that is hard 2 catch is beldum. Only move he knows is take town. so u need to bring in a ghost false swiper and a ghost poke to put a status effect on it. Even after that it is still hard 2 catch. Like Kamino said. I can understand that u are sad about the situation, but its not a reason to lower the catch rate. Maybe u should prepare ur self better if you want to catch a legendary in the future. And nice to read btw i liked the story ^^

Catch rate can't be changed, it's an official stat of the pokémon.
