||book-bats are made from old or worn out books that have been animated to guard the library. They are not hostile but do have an interesting ability to mesmerize would be thieves in the shelves. Once a thief is mesmerised ( 1 attempt per action), they sit and read the book, oblivious to anything else until the library own frees them with a counter command. They will come slowly back to there senses, refreshed and feeling they have had a good read, but not really remembering mush of the book read.(intensity 8 for dispelling purposes).
Some have more detrimental erects, but most are to prevent reading of sensitive material, or theft of books from university libraries. the person will not let the book go willingly and will resist with opposed brawn, adding the book bats brawn to theirs. Seeing as it is limited to one book per trespasser, most large libraries have 4 or 5 book bats to guard them.
They appear, quite simply, as a book that uses its covers to fly.
Hit locations are:
Body = pages
wings = front and back covers
Head = spine (need to hit here to destroy)
if a 'wing' is destroyed they fall to the floor and can be destroyed easily.
Uses INS not INT.
