Explanation

So in Return of the King, when the Witch King is stabbed with a barrow blade it makes him vulnerable and disintegrates.

General idea

Now while it would be kinda ridiculous to make them break instantly. Barrow Blades could do extra damage (1.5X makes sense to me) but it drains more durability to wights and even hit the dead marsh wights.

Wights

These would drop the ancient armor and weapons pieces. However once upon being hit by one once they can be damaged by other normal weapons.
