Mints are items that will make their first appearance in these games. They’ll impact which stats of your Pokémon are likely to grow faster than usual! Each Pokémon has a Nature, and this Nature can impact which of the Pokémon’s stats are likely to grow faster or slower than average. Using a Mint on a Pokémon seems to change these stat-growth patterns! However, a Pokémon’s Nature itself won’t change even if you use a Mint.
Nutritious drinks like Protein and Iron raise a Pokémon’s base points, which in turn help raise that Pokémon’s stats. Until now, there has been a limit on how many of these items could be used on a Pokémon. However, in Pokémon Sword and Pokémon Shield, you’re now able to max out a Pokémon’s base points using only these supplements!
If two Pokémon are of the same species but one has more base points, the Pokémon with more base points will grow to be stronger!
Normally, your Pokémon earn Exp. Points through battles. But if you use an Exp. Candy, you’ll be able to give your Pokémon Exp. Points directly! You can earn these Candies in Max Raid Battles, so collect a bunch and level up your Pokémon in a flash!
Sometimes, a Pokémon hatched from an Egg will know unusual moves called Egg Moves. These Egg Moves are moves that the Pokémon wouldn’t normally be able to learn through more common means, like leveling up or using TMs. In these games, if you leave two Pokémon of the same species at the Pokémon Nursery together, an Egg Move that one of them knows can be passed on to the other Pokémon!
It appears that a Pokémon can only learn an Egg Move this way when it knows three or fewer moves.
