I would like to suggest that this skill doesn't allow you to check the "use a white scroll" option if you don't have one in your inventory, if possible. Today, I was scrolling a perfect weapon with this skill and I assumed I still had WS left because the "use a white scroll" box was checked. I know it is my fault for not verifying while scrolling, but it would be nice if it didn't allow you to check the box when you don't have a WS in your inventory.
