How to obtain a Bastiodon in Pokemon Brilliant Diamond and Shining Pearl

Evolution is an important aspect of the Pokemon franchise. Creatures begin life in one form and often find themselves evolving into a much larger and stronger form after meeting a certain goal.

Bastiodon is one of the latter forms. To get your hands on one, you'll need to evolve a Shieldon. That requires you to obtain the Armor Fossil to get a Shieldon in the first place.

It is safe to assume that Brilliant Diamond and Shining Pearl will have many of the same locations and items as the original versions of these Pokemon games. That means finding the Armor Fossil won't be too difficult.

The Sinnoh region has a hidden underground area where players can hang out, create a base, and find all sorts of rewards. The Armor Fossil is one of those rewards.

Originally, it was exclusive to Pokemon Pearl, so that may carry over to the remakes. If true, you need to mine in the Sinnoh Underground for a chance to receive an Armor Fossil that you can revive.

After acquiring an Armor Fossil through mining in the Sinnoh Underground, you need to revive it to receive a Shieldon. Revival can be done at the Oreburgh Mining Museum.

The museum is located in Oreburgh City. It contains rare items and displays regarding the city and its mining operations. Just approach the man at the counter, give him the Armor Fossil, and wait to receive a Shieldon.

Now that you have a Shieldon in your possession from reviving the Armor Fossil, you need to evolve it to get your hands on a Bastiodon. All it takes it getting Shieldon to level 30.

This is done by gaining EXP through battling wild Pokemon and other trainers. Use an EXP Share to ensure Shieldon gains EXP even if it is not in the battle. That will help it level up much quicker.

Once it hits level 30, it will evolve into Bastiodon. You will then have the Rock/Steel-type Pokemon with an insanely high 168 base Defense stat and a 138 base Special Defense stat.
