To be honest this should (in my humble opinion) have been done already, but I think that there is no reason to prevent holy white scrolls from going onto things other than Armor, swords, and tools. For 2000 souls, if somebody wants to put a holy white scroll on their ssv bow I see no reason not to. Or for instance a holy protected flower Just an idea, and not one that would be explicitly hard to implement, that would be nice to have, especially as I've seen numerous people agree with the idea.
