As you progress through Dune Awakening you will no doubt start to find yourself looking for Diamondine Dust. That's because this rare material is required to build your ornithopter.
In addition to being required for the ornithopter, it is also a component in other crafting recipes such as vehicle hulls and short blades.
This is a very restricted resource but there are a couple of places you can source it reliably, so worry not.
Farming It In Mysa Tarill
Mysa Tarill is located just south west of the Eastern Shield Wall and is accessible by driving alongside the cliffs just north of Western Vermillius Gap.
Be warned that this is a higher level zone, so if you are still fairly early in your journey, you will likely just want to shield up, loot and then make a hasty exit.
You can see this location within the orange circle on the left side of the map in the image below.
Within this location you will find a bunch chests that you can loot that can contain Diamondine Dust, amongst other useful items like Carbide Scraps. I've included a route below which loots five chests containing Diamondine Dust and only takes a few minutes.
Enter from the east, where the arrow is shown. This will take you into a small cave where you can loot the first chest (1).
Pro Tip: Leave your vehicle outside the main entrance once you leave the cave. That way if you die, you can easily respawn just moments away.
Continue through the cave until you approach one of the main entrances to the courtyard. Run through, ignoring the enemies, and then when you hit the courtyard run up to the alter beside the head of the snake. There are two chests on each side of the alter you can loot (2 & 3).
Exit the courtyard through a side passage, run towards the end and then hang right to make your way back to the main entrance. You'll hit a wall you can climb to get out and just before the wall you can grab another chest (4).
Get back on your vehicle and then drive alongside the cliffs up to a camp at the top of the structure. Run in and grab another chest there (5), about half way in the main chamber, before making your exit.
Pro Tip: Combine this trip with our Aluminum Ore farming route when you are done because there is an area of the Eastern Shield Wall just east of this location that is teeming with Aluminum Ore.
Buying It From A Vendor
Given how easy it is to gather a decent amount of Diamondine Dust from Mysa Tarill, I hesitate to recommend buying it from the vendor, however it is an option.
In each of the two major commercial/social hubs (Arrakeen and Harko Village) you can buy the Diamondine Dust from the Weapons Vendor for 3,500 Solari.
This will require you to be at a Reputation Level of 4 with either faction however, as shown in the image above, so keep that in mind.
