Investigate the deaths in the Umar Hills. There's a shadow dragon that will drop the Crom Faeyr scroll fairly deep into the temple ruins.

it's nice that you have the girdle of storm Giant str but it's not what your looking for, you need girdle of Frost Giant Strength located in the Kuo-Tao city in the under dark, you need to summon a monster on the Gorgan alter, the girdle is on one of the death knights you must defeat.
