Wondrous item, very Rare

To create a Construct, you must pay the specified cost in supplies and spend the time shown on the table, working without interruption with the manual at hand and resting no more than 8 hours per day.

After every 10 days of labor, you must make a DC 10 Dexterity check using smith’s or tinker’s tools. On a failed save, you make no progress in those 10 days and waste a proportionate amount of supplies (e.g., when constructing a runeward golem, failing a check means wasting 1/5th of the purchased supplies). Whether you succeed or fail, the DC of this check increases by 1 after each time you make it. Once you’ve succeeded on enough checks to finish the Construct, the book is consumed in eldritch flames. The Construct becomes animate when the ashes of the manual are sprinkled on it. It is under your control, and it understands and obeys your spoken commands.
