Weapons ineffectice(minor spoilers)

I can't kill the "Shadow" enemies on my way to the Vale of Shadows, it says that my weapons are ineffectice. Why is that?(I can hit the "Lesser Shadow" enemies).

You should have at least one character with a +1 weapon by that point. Just have that guy and your mage or Druid focus on the full shadows and have everyone else mop up the lesser shadows.
