Hermione Granger considered this book along with many others as she was deciding on the supplies they would need to take on their mission to find Voldemort's Horcruxes. As she was sorting books, it broke free of its restraints and bit Ron Weasley on the ankle. It is unknown if she took it with them. [6] Curiously in said versions, there is always a single Book in the Charms classroom that is in a defeated state groaning throughout, but can always be refought whenever the flying books from the shelves are defeated either through casting Flipendo or Snufflifors at them. Once they are all dealt with, the Monster Book will reanimate itself with its health bar shown in full, and can be fought and defeated as normal. Exiting and re-entering the room allows this process to be repeated as many times as one wishes, accessible as soon as the Charms class is completed in the playthrough. Rubeus Hagrid chose the book for third years studying Care of Magical Creatures. He sent Harry Potter a copy but he had to use a belt to keep its jaws shut because he knew Vernon and Petunia Dursley didn't want to find it in their house. He put it under the floorboards of his bedroom to hide it. Hagrid didn't tell Harry why he needed the book. [1] Hasn' anyone bin able ter open their books? Yeh've got to stroke 'em." — Hagrid in his first lesson of magical creatures [src]

Condition Immunities charmed, crippling pain, exhaustion, frightened, incapacitated, poisoned, unconscious Now it's time to move outside to work with the silicone caulk. The fumes from the silicone are nasty and you will be using a lot of it, so it is best to do it outside. If you have to do it inside, make sure to have really good ventilation. This is messy stuff btw! Nimble Escape. The goblin can take the Disengage or Hide action as a bonus action on each of its turns. Actions Sense Emotions. A dementor's blindsight allows it to feel the emotion of any being within its range. Any attempt by a being to Hide from a dementor while within its blindsight radius automatically fails. Finally, we shaped the book's tentacles by mixing purple and white clay. This created problems later as these two clays took longer to cook when blended. Removing quarter sized pieces of clay for two sets of tentacles to line the jaws, we rolled out small pasta-like shapes and sharpened the ends. Gray clay was used as tiny suction cup dots underneath each tentacle. When making the tentacles we tried to make them one-of-a-kind because, like humans, each book monster should have its own unique personality. When we finished with the first four tentacles, the rest were formed by dividing the remaining clay into relatively small, similarly sized pieces.
