Golem Manual

A golem manual contains information, incantations, and magical power that help a character craft a golem. The instructions therein grant a +5 competence bonus on skill checks made to craft the golem's body. Each manual also holds the prerequisite spells needed for a specific golem and effectively grants the builder use of the Craft Construct feat during the construction of the golem, and grants the character an increase to her caster level for the purpose of crafting a golem. Any golem built using a golem manual does not cost the creator any XP, since the requisite XP are "contained" in the book and "expended" by the book during the creation process.
The spells included in a golem manual require a spell trigger activation and can be activated only to assist in the construction of a golem. The cost of the book does not include the cost of constructing the golem's body. Once the golem is finished, the writing in the manual fades and the book is consumed in flames. When the book's ashes are sprinkled upon the golem, it becomes fully animated.
