Zozthrea was a well renown wizard making many spells, potions, and magical items she would work with Professor Radiant helping with the magical side of his inventions. One time Zozthrea was working with Professor Radiant she had an idea, to make a book that can improve the ability of magical items.

After reading this book for 48 hours you get to choose an amount of objects equal to your proficiency bonus for you to be able to create. You also get to choose half of these to have increased effects.

When you are creating an object it takes materials worth at least the price of the object - 10 Gp (Unless that becomes 0 or less then the price of materials equals the price of the item). When you are making an upgrade it takes materials worth at least the price of the object - 15 Gp (Unless that becomes 0 or less then the price of materials equals the price of the item). It takes 30 - (intelligence modifier + level) hours to create a object and if you are creating a upgrade it takes half the time of the item.
