The Ability Patch: A new useful item for raising Pokémon
In The Crown Tundra, you may get new items called Ability Patches. They’re hard to come by but worth the effort. If you use one on a Pokémon, its Ability will change to its species’ Hidden Ability, if it has one! With an Ability Patch and a helping of Max Soup from the Isle of Armor, you can bring out the Hidden Ability of the first partner Pokémon you chose at the beginning of Pokémon Sword or Pokémon Shield and give it the capability to Gigantamax as well.
