Magic Powder

Alright I have been scouring the web for the past 30 minutes and I cant seem to find anything relating to this. So what is the easiest way to get these purple magic powders? I Tried hunting for those Wisdom Crystal Ores but my god... so hard... what ore can you refine to get the powder as biproduct? Please help >_< I need them

If you dont know but just so happen to have some on Khaini contact me lol xD
