How to farm Pustrels in Warframe

Pustrels are a new type of ore that was added to Warframe in the Rising Tide update. This ore can only be mined on the Plains of Eidolon and can only be dropped while farming The Red Seams. One of the best places for mineral cultivation on the Plains of Eidolon, including Pustrels, is at the cave right next to the lake at Twin Horns. This deep cave system is filled with ore veins.

To mine for the ore in the Plains of Eidolon, you will need a Nosam Knife from Old Man Sumbaat [Cetus] or a Sunpoint Plasma Drill from Smokefinger in Fortuna. Both can be purchased from Standing for the corresponding unions. To gain status, do The missions for Konzu in Cetus or Eudico in Fortuna.

Equip your mining tool for your cogwheel, then load it up in the Plains of Eidolon. When you choose the explore tool in the cogwheel and hold it in your hand, it will fill the veins of ore markers on your minimap, as long as they are within a certain radius. It will also emit a beep that increases in frequency the closer you get to a vein. The veins appear as blue or red lines on the rocks, but to get Pustrels we are interested in the red veins.

When you find a red vein, aim it with the extraction tool, and one to three light spots will appear on it. Hold the trigger button down to shoot one of the dots, then carefully observe the color bar that will form around the center of the screen. You must hit a target, indicated in parentheses. These can travel back and forth, stand still, or be very thin. Ideally, you want to stop shooting when the color bar hits the center of these spots. The more precise you are in this process, the more you will get The res
