If you want to complete the 2023 Adventure Week Collection Challenge in Pokemon GO, you’ll need to get a Bastiodon. However, this is easier said than done!
Many Pokemon trainers may be stumped as to how to get a Bastiodon in the Skull & Armor section of the Adventure Week Collection Challenge. This is because it doesn’t actually spawn in the wild.
However, the solution to getting this Rock/Steel-type ‘Mon lies in evolution, rather than catching!
How to Get Bastiodon in Pokemon GO 2023 Adventure Week

Luckily, Shieldon is one of the common wild spawns during the 2023 Adventure Week event. Therefore, collecting this much Candy should be pretty simple and speedy!

Even if it shouldn’t take too long, there are also a couple of you can speed up this process.
Firstly, you can use Pinap Berries or Silver Pinap Berries to boost the Candy you earn from each Shieldon you catch. This is by far the fastest way to increase how quickly you’ll be able to evolve Shieldon into Bastiodon.
Additionally, you can use items to increase how many Shieldon you encounter. Incense, Daily Adventure Incense, and Lure Modules are the best ways to attract more Pokemon to you.
