What is the Problem with Sinnoh Underground

[Oguzkaya34]

It’s been almost a week, and we keep getting these ridiculous crystal numbers. We always end up missing 2–3 parts because the crystal amounts are completely unbalanced. What exactly is the problem here? We’ve been dealing with this for 7 days. Why are the crystals not distributed in a more balanced way?

Hello, here's a quick tip: Bring along Pokémon that know the move Dig specifically ones matching the type of the Crystals you need. They require a certain level of Happiness to work consistently. Also if you fight the Archelogist NPC he will tell you which Crystals are the most used one.

 

I hope I could help you a little bit

Hello @Oguzkaya34! I'm sorry for the inconvenience. As @Descheinrobbe said, it's very useful bring water, fire, rock and ground Pokemon (along with the Grass type Pokemon needed to access to the Arboreal Area). Remember that each Pokemon needs 252 happiness, (happiness have tool tips in the Pokemon card).

To raise happiness you can defeat wild pokémon while holding a soothe bell, or use the little cafe, located in Cerulean House 5 and Goldenrod Underground Path here you can also find the Pokémon Salon.

You can check this list of Pokemon that can learn dig (by level and TM), you can also find all the locations where you can buy the TM. 
And Here's a guide that may help you complete Sinnoh Underground.

Let me know if you need anything else!
Regards.
