Dalyte's Supplemental Book of Spells

Overview
This book is magically infused with self sustaining arcane energy. The book has 4 charges and regains 1d4-1 charges at each sunrise. Wielding the book even a novice is capable of casting very simple rudimentary spells. Each time the wielder uses the book to cast a spell they have a chance to incur a level of exhaustion. The process of crafting this spellbook was pioneered by the Mapheus University. (See Alilnegi Inventions)

Function
The book has three spells listed within its pages. More spells cannot be added to its pages. The crafter of the book placed an arcane focus on the books cover and provided extra runes within the books pages that allows the book to cast spells through the arcane focus on the cover when a command word is spoken. The wielder must still perform the somatic components which are clearly listed on each page. When casting a spell the book's magical effects perform the necessary verbal components of any spell.

Any spell cast from this book uses intelligence as the spellcasting ability score. If any spell cast requires a DC the DC is equal to 10 + your intelligence modifier. Casting a spell uses one charge of the book's 4 charges. A wielder can choose to expend more than one charge at a time. Each additional charge spent raises the spell level of the spell being cast by 1.

Non-casters attempting to use this spell book are not accustom to channeling arcane magic and doing so causes them to experience extreme fatigue. The more charges a book is missing the harder it is for a supplemental book of spells to cast a spell without causing fatigue. Whenever a spell is cast from the book, the wielder must make a constitution save DC 14 or suffer a level of exhaustion. This DC increases by 4 for every charge missing from the book.

Unstable Magic
This method of channeling arcane magic requires an unsafe method of inscribing runes through the book. If the book is ever damaged without the glass arcane focus on the cover being broken the magic inside the book runs rampant and explodes. All creatures standing within 5 ft of the book when the magic disperses must make a DC 14 dexterity save or take 2d10 force damage per charge remaining in the book.

Spells Inside the Book
When the book is being crafted, any first level spell from any class can be added to it's pages. If the book is randomly generated roll 1d4 on each of the tables below to determine the three spells inside the book.
