Question: pokemon sword and shield how to evolve ninjask?
Answer: All you need is a Nincada, and a spare PokéBall. Have Nincada in your party, as well as one additional open slot (so, a total of five or fewer Pokémon in your party), and at least one PokéBall in your bag. Then, evolve Nincada into Ninjask by raising it to level 20.
