A homunculus is shaped from a mixture of clay, ash, mandrake root, spring water, and one pint of the creator's own blood. These materials cost 50 gp. After the body is sculpted, it is animated through an extended magical ritual that requires a specially prepared laboratory or workroom, similar to an alchemist's laboratory, and costing an additional 1,000 gp to supply. If the creator is personally constructing the creature's body, the building and ritual can be performed together. A homunculus with more than 2 Hit Dice can be created, but each additional Hit Die adds +2,000 gp to the cost to create.
