Ok, I believe I figured out how to start dealing decent damage. I upgraded the 4th stat and it seems I deal more damage. I can now at least destroy the rubble and enemies seem to die in less hits.
Edit* Oh I get it now! There's mining nodes scattered about that you can forage for minerals. Ok, now this makes it easier!
