So, I've found a couple things to "raise IV stat by 1", and I can view said stats, but I can't find any explanation either in game or on the cobblemon site explaining what IVs (or EVs, for that matter) actually are or how they work. Googling just led me to the cobblemon page about "Hyper Training" where it says you can raise the stats, but that's not exactly helpful without information on how the system works. Is there anywhere I can find this out (preferably by reading)?
