You do realise that this activity is possibly the absolute worst way to try to find arsenic?
Before your brain melts and drips out of your ears doing that, maybe take a SRV onto the surface of a body that has arsenic
* in it's makeup and go shoot meteorites and outcrops.
Failing that, go collect G4 elements and G4 and G5 encoded data at the Bug Killer in your SRV and trade tellurium, ruthenium or antimony for arsenic.
* Insert name of your current system in the "reference system" field, select arsenic in the "material finder" field and click "find bodies":
Bodies in Elite: Dangerous - search, filter, find and sort systems ... and find the materials you need!
