Potent Dust is crafted by accessing a Mortar and Pestle or an Industrial Grinder and crushing 1 × Ancient Amber in your inventory. Crushing 1 × Ancient Amber at a Mortar and Pestle produces 2 x Potent Dust whilst crushing 1 × Ancient Amber at an Industrial Grinder produces 6 x Potent Dust. :)

This also gives a bunch of xp to yourself or the dino you use it on
