Secretorum Hermetis

Acrid odors cling to this stained, heavy volume. The book's metal fittings are copper, iron, lead, silver, and gold, some frozen mid-transition from one metal to another. Upon first inspection there doesn’t seem to be a way to open the book.

Found on Nolla Isle and carried by Eldron.

An identify spells will reveal everything below but to open the book and gain access to its spells and charges you will need to attune to it through a grueling eight-hour ritual during which you give up a 1st level spell slot, 1 hit point, and 100 gp of precious metals for as long as you are attuned to it.

This 4 lb book contains the following spells: chromatic orb, cloud of daggers, flesh to stone, magic circle, plane shift, purify food and drink, Tenser's floating disk, vampiric touch. It functions as a spellbook for you. While holding it, you can use it as a spellcasting focus for your wizard spells.

The book has 13 charges. You can use the charges in the following ways while holding it:

• If you spend 1 minute studying the book, you can expend 1 charge to replace one of your prepared wizard spells with a different spell in the book. The old spell and the new spell must be of the same school.
• As an action, you can touch a nonmagical object that isn't being worn or carried and spend a number of charges to transform the target into another object. For 1 charge, the object can be no larger than 1 foot on a side. You can spend additional charges to increase the maximum dimensions by 2 feet per charge. The new object must have a gold value equal to or less than the original.
• When a creature you can see within 30 feet of you makes an attack roll, an ability check, or a saving throw, you can use your reaction to expend 1 charge and force the creature to roll a d4 and apply the number rolled as a bonus or penalty (your choice) to the original roll. You can do this after you see the roll but before its effects are applied.
• When you cast a wizard spell, you can expend 1 charge to cast the spell without verbal, somatic, or material components of up to 100 gp value.
• When you cast an abjuration or transmutation spell, you can expend 1 charge to grant a creature you can see within 30 feet of you 2d10 temporary hit points.
