Manual of Iron Golems
Equipment
To create an iron golem, you must spend 120 days, working without interruption with the manual at hand and resting no more than 8 hours per day. You must also pay 100,000 gp to purchase supplies. Once you finish creating the golem, the book is consumed in eldritch flames. The golem 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.
