The Isle of Armor is the setting of Pokemon Sword and Shield‘s first expansion, but aside from the Master Dojo–where you’ll earn the new Legendary Pokemon Kubfu–the island lacks many of the facilities you’d find around mainland Galar, such as a Pokemon Center and an item shop. And while you can’t build a Pokemon Center on the island, you can at least add some more amenities to it.
After you reach a certain point in the story, you’ll have the option to upgrade the Master Dojo with additional features and supplies. These upgrades can be rather pricey, but they are generally useful, especially if you have a few thousand Watts to spare. We’ve broken down what all the Master Dojo upgrades are and how much each costs below.
If you’ve just picked up a Sword or Shield Expansion Pass, here’s how to access the Isle of Armor and how to evolve Galarian Slowpoke. We’ve also put together a guide explaining how to teach Pokemon to Gigantamax. Even if you don’t have the Expansion Pass, you still have a few ways to get the newly added Pokemon without the DLC.
