Book Bonding

As part of casting this spell, you must expend at least one Hit Point Die or the spell automatically fails. You target a book of your choice within range and create a protective bond with it.

Once you’ve created a bond with your chosen book at the end of the casting of this spell you will roll the expended Hit Point Dice adding your constitution to the result. You take necrotic damage equal to the result of this roll, this damage cannot be prevented or lessened in any way. The chosen book and you then gain a handful of benefits from this bond.

* The book gains a number of Hit Points equal to the necrotic damage taken. These Hit Points get replenished after taking a long rest with it in your possession.

* The book gains a number of Hit Point Die equal to the number expended. These Hit Point Die can be used to replenish the books hit points when taking a short rest or can be expended when casting Sangromancy spells. The Hit Point Die get replenished after taking a long rest with it in your possession.

* The book gains immunity to all damage except fire and resistance to fire damage.

* You may use an action to send the book to a pocket dimension, later using an Action to bring it out.

* While on the same plane of existence you can use an action to summon the book to you. This can be prevented by any amount of lead which must completely encase the book.

* If the book is on another plane of existence you always know what plane it is on and the most direct route to take to get to that plane if one is available.

* If the book is destroyed while bonded to you, you may use an Action to take necrotic damage equal to it’s maximum Hit Points, this damage cannot be prevented or lessened in any way, to recreate the book at full health.
