It looks like it is not possible to mod an item by using its number (under the patch 2.16, which should make this sort of modding possible). Changing the path requirements of the Bane Blade/Sword of Sharpness doesn't work when using their unique numbers; using the name only alters the one-handed sword. It looks like it is possible to remove both from the game however. I will create a thread shortly about those two weapons, as it could be my mistake rather than any bug.

On the same matter, both Staffs of Elemental Mastery appear to have the same ID (238), even though their effets are slightly different. They also have the same name ("Magic Staff", oddly enough), but otherwise behave as the Bane Blade/Sword of Sharpness.
