Out of the 4 available materials (Spinmetal, Helium Filament, Spirit Bloom, Relic Iron) which one can be farmed the quickest? I.e. most per hour... Spinmetal in Rocketyard I can net about 80-100/hr. I haven't clocked Helium Filament or Relic Iron. The route I take for Spirit Bloom is incredibly slow... Edit: I'm only doing this to obtain crucible marks. The character that I'm playing (trying to role play) doesn't like the idea of crucible so doesn't compete in there. But needs to get armor from FWC.
