Is there a place where I can check the chances of encountering a given Pokemon?

Greetings @Igorekziomal

As far as I know, there are sadly no ways to check the exact chance for a specific Pokemon to spawn in tall grass. The closest thing to that would be to use either the PRO Wiki, which has spawn lists including rarity tiers for the Pokemons on their respective page, or to use the Reborn Bot with the /spawns command on the PRO Discord: that will also give you that list for either the Pokemon or the Map you're checking the rarity tiers for.

Another option would be to use PRO Better Farm: this is an extra tool that helps you monitor all of your encounters, therefore giving you the number of times you encountered a specific Pokemon, and the corresponding percentage.

Did you have any other question related to this topic?

thank you very much for your answer. That's it
