I know this is kind of a stupid question, but i was away for a long time and cant remember where is the crystal shop on the map.. I have some things to fragmentize. Anyone can help me please?

Go to the Darkside on the map and at the bottom of the map next to the Asmodeus Lab is the Fragmentizer. The shop can be found there. c:

Ohhhh thanks a lot !

You can also use the link from the "other currencies" section of your vault. I use it a lot for the Subeautique link :).
