A small door on the chest of the library automaton opens into an extra.dimensional bookcase. This bookcase functions exactly as a bag of holding except that it can store only written materials such as books, scrolls, tomes, parchment, folders, notebooks, spellbooks, and the like.
The library automaton chooses one creature it can see within 40 feet. The target must succeed on a DC 12 Intelligence saving throw or take 9 (3d4 + 2) psychic damage and have disadvantage on Intelligence-based checks, saving throws, and attacks until the end of its next turn. If the saving throw succeeds, then the target takes half damage and suffers no other effect.
This ability functions as the cantrip mage hand but can be used only on books, scrolls, maps, and other printed or written materials.
