Shades are aggressive level ? mobs. They are incorporeal, and cannot be bashed. They can also sneak.

A shade is here, shrouded in an inky blackness.

This dark form is evil to the core, a true corruption of Morgoth. It wears dark
robes that seem to suck up all light. As you examine it you sense the hatred of
all life that this suffering creature feels.
