Relationship between nebulite slots and innocence scrolls?

I recall there was something about this, but I don't remeber the details. I think it was either:

A) Can't use innocence scrolls if the item have a nebulite slot.
B) Can't use innocence scrolls if the item have a nebulite mounted.

There is a thread on Basil that claims the scrolls work even on an item with a mounted neb, but I thought I'd see if anyone here have any experience with it.

Thanks for helping out!
