Protein/en

Protein is a consumable item which can be purchased from each Region's League, or traded for Berries with the Berry Master of each region from Johto onwards. It can be fed to a Pokémon to increase the amount of attack that Pokémon gains by 1 per protein per hatch. Each Pokémon can consume a total of 5 proteins per unlocked region.

How to Use
Go to Start Menu > Items > Item Bag, select the protein and select a Pokémon to use it on. Once used, the effect is permanent and cannot be removed by any means.

New Efficiency
Below is a list of the most efficient Pokémon to breed accounting for both the Regional Damage Debuff and Proteins. Breeding efficiency is determined by the following formula:

$$ \colorbox{White}{$ \text{Egg Cycles} = \frac{\text{Egg Steps}}{40} $}$$

$$\colorbox{White}{$ \text{Breeding Efficiency} = \frac{0.25 \times \text{Base Attack} + \text{Proteins Used}}{\text{Egg Cycles}} $} $$

 How to use these tables 


 * Region - Use tables from the Region you want to gain more damage in. (Ex: If you want more damage in Sinnoh, use the Sinnoh tables)
 * Attack Debuff/No Attack Debuff - If you have the Attack Debuff Challenge on (activated by default), use tables that say "Attack Debuff" in the header. If you do not have the Attack Debuff Challenge on, use tables that say "No Attack Debuff" in the header.
 * Max Proteins/No Proteins - If you have the No Proteins Challenge on (not activated by default), use tables that say "No Proteins" in the header. If you do not have the No Proteins Challenge on (default), use tables that say "Max Proteins" in the header.

Price
When bought from the Indigo Plateau / Pokémon League, the price for Protein rises irreversibly, similar to Masterballs. It starts off at 10,000, increments by a factor of 1.1 every purchase, and caps at 1,000,000 after 49 purchases.
