Hey :)

With the new crystal setup, the Dim Magicl Crystals are actually worth using when lifeskilling.

The only problem is, they are all out of stock on the MP, and they are not obtainable after doing the 1 time family quest.

Is there any other, secret way of obtaining then? or does anyone know if PA have any idea of implementing other ways to optain them?

Hello, you posted in a Tips and guide section of the forums which is meant for tips / guides. In the future you should defer your questions over to The Oasis of Knowledge.

For knowledge specific items you can try BDOCodex and for this item in particular it's https://bdocodex.com/us/item/15044/

If you scroll down you can see how to obtain it and it says

1. [Level 20] Now It Gets Interesting...

2. You reached [Farming Apprentice]!

Unfortunately I don't know any other way.
