Been loving all the new content in the Arcana mod recently. Dove in for the first time about a week ago, after a big update that apparently added the requirement to get EPPs for Arcane, Superstorm, and Illuminated planets.

Both the Superstorm and Illuminated EPP require Holosium, but as far as I can tell, you can only find Holosium on Illuminated planets. Is there some other way to get it? 'Cuz if not, it seems like you have to beam down to a planet surface, get lucky and hope to find some right away, and constantly be healing to protect yourself from the radiance status.
