You can now set specific spawn chances for each mob, per rarity. So you can have a default chance of 1% but make cows have a 5% chance of becoming rare, 10% chance of becoming unique, etc..

You can now breed two RareMobs (or a RareMob with a basic mob) and their baby will turn into either the mother's or the father's rarity. For example, a basic mob bred with a unique mob will have a 50% chance of their baby becoming a basic mob, and a 50% chance for a unique mob. Two legendaries bred together will have a legendary baby. For this option to work, BOTH of these options have to be set in your config.
