Monster Manual III
This haggard humanoid creature stands in a small cloud of dust. Its stonelike features seem eroded and crumbling, like an ancient statue battered by the elements.
Dust wights are hateful creatures formed by a conjunction of elemental earth and negative energy. They seek to tear down and destroy all creations of stone and metal, and if they have to kill living creatures to do that, so much the better.
A dust wight looks like a gaunt, human-sized earth elemental with forever-crumbling features. Despite its worn appearance, it weighs about 400 pounds.
Dust wights speak Terran.
This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Earth. Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock.
