I second the Spring-Loaded Wrist Sheath and Scrolls debate!
Is the list given (that doesn't include scrolls) exhaustive?
If not, would removing the scroll from a Spring-Loaded Wrist Sheath destroy the scroll, making it useless anyway?
If not, would removing the scroll from a Spring-Loaded Wrist Sheath (a swift action) provoke an AoO?
Those are the three questions that always seem to go along with it.
