Due to their nature, equilibrium players have always been forced to adapt, finding ways to survive in a world that has been hostile. They are not great manufacturers and they are not even amazing riders, but they have always been good in finding the best opportunities to save some money.
Recently they have learned that there is a way to spend less coins for creating and entering shows.
As a result the equilibrium players have a new specialization; the savings spec.
When equilibriums enter their horses in shows, there is a small chance that they learn how to save money for that show type and their spec/skill will increase.
The higher their spec is, the higher the discount for entering and creating shows (of that type) is.

Example:
Creating a dressage show with a prize of 100 coins:

Manufacturers will pay 100 coins
Riders will pay 75 coins (riders get a 25% discount)
Equilibriums will pay 90 coins (due to the 10% discount) if they do not have the saving spec for dressage shows.

If an equilibrium has a 50% savings spec for the dressage show he/she will have to pay only 56 coins (instead of 100)
If the spec is at 80% the equilibrium will pay only 36 coins.
Finally, when the spec is at 100%, the equilibrium will pay only a quarter of the price. In this case it would be 22 coins.

So for an equilibrium there are 2 discounts: First the 10% discount, and then the spec discount.
100 coins => 90 coins (thanks to the guild discount)
90 coins => 22 coins (roughly a quarter of 90)

Same formula applies for entering shows.
