If the Cube of Paradox was an elemental ego weapon, then it might have some use, but it uses Arcane Energies. Although the scales will not be useless, but it will not help in upgrading. Adrian can only sigh with an exhausted expression as he is in front of priceless treasures but does not have much use for them.
Adrian actually wanted to get at least one scale for himself so that he could use it to upgrade his armor. He is missing the wind element to complete the elemental resistance of his armor. Then again, this are Pann's items not his, but he might get something if he behaved well.
