The small gold ingots out of the Shadowlands can't be used for this process. The Soul Fragments you need for the VTE drop often from Medusas or Martial Artists Monsters. Many Medua monsters can be found in the East of Deep Artery Valley they also drop varius rings and bracer that can be melt and transformed into Gold. Robot junk can be found from any robotic monster, such as those found (near Alvin) but for this use you will need higher ql junk so you will probably need to kill slayerdroids, such as the ones found near Lush Hills Resort or from high level missions.
