Notice of White Scroll Removal

I had never used one and was curious if this is how they worked; like Lucky Days or Protects. Does this mean I can Shield an equip and pass it around like the local tramp to pick up all sorts of Positive Chaos?

A protect scroll only protects an item once, whether the scroll you use passes or fails it is used up. I believe it is the same with Shield scrolls.

Edit: Man there are so many scrolls with similar names I'm confusing myself.
