Breeding/Rate V

Every dificulty has 1 slot unlocked on default (1:1:1). In order to unlock the others you will need a specific ammount of rate value. This value is in fact the current earning of your two dragons:

What is base gold/ increase gold?

 * Every dragon has a base gold (gold/min at level 1) and the increase value (added for each level after). You can find these number on the dragon page, in the infobox, notice at this  Generation :  and take the numbers in the bracet. There are usually 3 numbers in the bracet, and the display should be (base gold/ increase - difficult group)

Calculate Earning Rate
​ Let's rewrite the 3 array of Difficult 1 2 3 into this:
 * 1) If the level is smaller or equal to 10: Rate = Base + Increase * (level - 1)
 * 2) If the level is greater than 10: Rate = Base + Increase * 9 + 0.5 * Increase * (level - 10)
