This tome, along with anything written on its pages, can’t be damaged by fire or immersion in water. In addition, the tome doesn’t deteriorate with age.

When a creature touches the tome (providing that it is not currently bound to another creature) the tome attempts to sever previous connections of the creature and forge new connections with the tome itself. once a creature is bound to a creature it cannot be unbounded short of death or a wish spell. If the creature is willing the tome strips all current levels of the creature and replaces them evenly with levels of warlock. If the creature resists they must succeed on a dc 13 wisdom saving through if they fail the creature lowers their constitution score by 2. whether or not the creature makes the saving through the tome takes half of the creature's current levels rounded down and converts them to warlock levels. if the creature has no levels in any class then the creature must succeed three death-saving throws and remove 2 points from its constitution score. if they succeed in the saving throws then they gain one level of warlock. If the creature has no connection to a draconic bloodline it must succeed three death-saving throws and subtract 2 from its constitution score. If they succeed only one of their levels is converted to a warlock level.

If a creature that is attuned to the tome dies there is a 20 percent chance that their soul is trapped in the tome and can telepathically communicate with any creature touching the tome regardless of language.

this item automatically attunes to an open attunement slot if there is no open attunement slot touching the tome has no effect on the creature.

If the character has no access to a breath weapon associated with their draconic ancestor they gain one use of the associated breath weapon per short rest.

Notes: automatically attunes
