DM advice - spell / enchantment over an area, which to use (like suggestion)

[LucyG92]

There is an ancient temple with a small library. Inside this library, I'd like there to be a permanent enchantment that causes people to be drawn away from valuable books/items and towards mundane or useless ones instead, while fully believing they are full of power/knowledge/whatnot. It would need to be cast by (evil) clerics. The idea is to protect against thieves and such. Does anyone have an idea as to what spell this could be? Or should I just make something up with an arbitrary save DC? Either way, I couldn't figure out if this is an Illusion spell or Enchantment?

Thanks for any advice.

Sympathy and antipathy on different books.

[Vatras]

Sounds like a variety of sympathy/antipathy plus some illusion.

Since it does draw people against their will, it has to be an enchantment. An illusion would make something (the paperbacks) merely attractive, but people would be free to ignore it. It would also almost certainly unravel when interacted with (= someone reads the paperback).

Technically you can place an antipathy spell on each valuable book, maybe tinkering with the conditions.

Secret page can be used to conceal or rewrite particular pages in books.

Guards and wards could be set up with a suggestion spell in the libray, e.g., "prefer the books with red covers" when the original collector rebound all the boring books in red.
