The IV Booster guarantees a certain number of perfect IVs for a Pokémon. In the configs, the points for this one are unique, as they are the number of perfect IVs, not a chance for anything.
Adds a chance for spawning Pokémon to spawn with their hidden ability, if they have one available. In the configs, there is a marbles property, specifically for this, as there is no inherent chance in Cobblemon yet for Pokémon to spawn with their hidden ability; this value serves the same purpose as Cobblemon’s shinyRate does for the shiny roll: It gives the y in the x/y chance for something to happen. The x is given by the points for the unlocked threshold.
Modifies the x in x/y chance for the shiny roll to succeed on a particular Pokémon. By default, it’s 1/8192. You can change the 8192 by modifying shinyRate in the main Cobblemon config. When a player unlocks a threshold, the formula becomes a quick 1+boost/shinyRate.
