Boosters

Boosters do exactly as their name implies; they boost rates, chances, or values. There are currently 6 built-in boosters: catch, ev, experience, friendship, iv, and shiny. Each booster is further explained in its corresponding section here. There is also 3 built-in holders: player, global, and world; explained here. Active boosters persist across reboots.
