A book with an unusual crescent shape; metal caps protect the tips. For a spine, it has a single, sturdy scrollwork hinge that curves along the middle part of the crescent's outer edge. It has an ironwood cover bound in leather. The book's pages are made from mica, cut to the thickness of a hair and polished smooth.

The book has 10 charges for the following properties. It regains 1d6 + 4 expended charges daily at dawn. If you expend the last charge, roll a d20. On a 1, the book loses its properties and becomes a nonmagical spell focus.

Spells. You can use an action to expend the book's charges to cast one of the following spells from it, using your spell save DC:

• entangle (1 charge)
• pass without trace (2 charges)
• protection from energy (3 charges)
• conjure woodland beings (4 charges)
• antilife shell (5 charges)
• find the path (6 charges)

Detect Poison. When the book comes in contact with any substance that is poisonous or corrosive, it became oddly prickly to the touch, allowing the bearer to detect poisons by dipping the book in a liquid, touching it to food, or waving it through the air when toxic gases are feared.
