Umbral Scouring is an Upgrade Item in that lets you purchase boss items when you exchange them as a currency with a certain NPC. There are many ways to obtain this material, from defeating bosses to traveling to the depths of the Umbral Realm. Those looking to farm enough Scouring for the right gear must collect plenty of Vigor or master the Soul Flay mechanic for the item.
Any Umbral Scouring you find in can be exchanged with Molhu at the Skyrest Bridge as an alternate currency for new weapons, armor, and shields. These items are paired with certain boss Remembrances to produce specific gear tied to certain Umbral Stigma. For example, defeating Pieta in unlocks her Sword, which costs 40 Umbral Scouring to craft.
