AMAZING TOOLS OF MANUFACTURE
Aura faint transmutation; CL 3rd
Slot none; Price 12,000 gp; Weight 1 lb.
Tools of this type always appear to be of the highest quality and wrought of the finest materials, most often mithral, darkwood, and adamantine. In the hands of a casual wielder, these items
simply appear to be magically enhanced masterwork tools for a specific Craft skill (determined randomly), granting a +4 circumstance bonus on such skill checks.
However, in the hands of a craftsman with 6 or more ranks in the selected Craft skill, the greater power of the amazing tools of manufacture becomes apparent. The wielder may use the tools to create items using the Craft skill much more surely and quickly. The wielder may take raw materials with a value equal to half the price of an object to be crafted, and produce a finished object in as little as 1 hour for an item with a final cost of 2,000 gp or less. For objects with a final cost of more than 2,000 gp, the wielder can perform 2,000 gp worth of work in a single hour, but only once each day. Only a single skill check is required to successfully complete the item, made on the last day of crafting and gaining the +4 circumstance bonus granted by the tools.
Requirements Craft Wondrous Item, Master Craftsman; Cost 6,000 gp
