Skill Patches will allow players to unlock hidden abilities within their Pokémon in Brilliant Diamond and Brilliant Pearl. Many Pokémon may have a hidden ability in addition to their normal abilities, and some of them can be quite powerful.
To get the skill patches, players will need to reach the post-match. This means beating the Elite Four, then going to the Battle Park. In the Battle Tower shop, players will be able to purchase skill patches for 200 Battle Points, which is quite a steep price.
Due to the high price of the Ability Patches in Brilliant Diamond and Shining Pearl, it is a good idea to think long before using them. It is also not possible to undo the change once it is complete, so it is a good idea to turn off autosave BEFORE making any changes in case you experience buyer remorse. It is also important to note that hidden skills have the potential to be passed on through breeding.
The most important thing to keep in mind about Pokémon with hidden abilities is that they cannot be caught in the wild. So remember that! Don't waste hours trying to catch a Pokémon with hidden abilities because it doesn't work that way.
