Blood Marble
From Miners Settlement - Game Wiki
Blood Marble is a rare material. Playing through the story of the Ruins of Elven Temple (Einlor) will grant you a total of 8 (?) Blood Marble, after that you can only get a maximum of 1 every 23h. The only permanent spawn of Blood Marble is located behind Sumbeor. You need to have one of the 2 Rings equipped to mine it. Currently there is no use for it in the game.
