Saw a guy on reddit who bred 2 tek parasaurs constantly and when the babies died he would farm them for dust and scrap metal. Ruthless, but efficient

Forbidden fun dip

When you are in the Extinction Map: Hit the Lamps, benches and Tables in the City with a Doedi. You get a lot of dust! Easy way to get Full Tech Armor.

Once you open the engram Element fron Ext, you can craft Element from the dust. Use a weight Argy and pump points into Doedic's weight as well to take more swings per flight. They do not get extra dust from melee points. Have been farming for a while to know the difference now 🙂

Take a good doed to extinction stay in sanctuary and attack every light poll and bench you see they pay out heavy in dust, electronics and crystal

Just vandalise the local benches tables and lamps in extinction to get easy element dust.

You can breed tek animals and kill the babies with a chainsaw and bam your farming element dust

Goodluck

All bionic Dino variants work as well to drop. I recommend using tek parasaurs for easy farming

Defense units can also drop this
