This is the third best Runecrafting pouch that can be obtained. After its 44th use, the pouch will degrade and hold only 3 essence. Further uses degrade the capacity even more. To repair the pouch so it can hold the maximum of six essence again, you must speak to the Dark Mage located in the centre of the Abyss. Essence contained in the pouch when it's dropped will be lost. A message will pop up and tell the player: "The contents of the pouch fell out as you dropped it!".
