Cobblemon Spawn Custom
A simple MOD to configure some customized properties from a spawned Pokemon, like IVs, Shiny and Hidden Ability chances.
About this Mod
With this mod you can change how many IVs comes with a specific value or allow you to change the probability to a specific pokemon spawns with a hidden ability or being shiny. Totally customized with a configurable file.
To find the species name, you will need to access the Cobblemon/AllTheMons github and look for the spawn_world_pool folder. Inside it are the spawn configuration files for the respective pokemon.
Look for the "pokemon" variable and copy the name that is assigned to this property.
Tip: For paradox pokemon with compound names, for example Iron Valiant, you need to leave the name with the space (iron valiant), otherwise it will not be recognized.
