Invested Device: Librarian's Aide

@Cathelineau

Following illusion rules described in Calebaïs book, when you create illusions you lure all five senses. A PeIm on the books of a storage would destroy all species (without Finess).

You do neither consider the basic PeIm guidelines (see ArM5 p.146 box), nor address, that ArM5 PeIm invisibility spells need to do much more than just destroy species to be effective (see Invisibility and Perdo Imaginem).
