The following crafting rules have been designed to both streamline the crafting process to involve minimal calculation or referencing, and also provide the DM with an additional avenue of creating adventure hooks for parties looking to forge the next legendary sword.

Requirements

This list of requirements can be specified for any existing item, magical or otherwise. Multiple creatures can participate in creating an item to fulfill these requirements if a single creature would not be able to.

Formula To create an item, a creature must first know the process required to make it. Many formulas are common knowledge to those proficient in their craft, however some might require training or a blueprint to follow. Common Knowledge This formula is known to any creature proficient in the required tools. Learned This formula must be discovered, either from a text or learned from another creature. After 8 hours of study, the creature knows it permanently. Blueprint This formula is so complicated it requires a set of written instructions to follow correctly, and can't be followed if these instructions are lost or destroyed.

Ingredients Crafted items only require one or two key components at most, which are generally their rarest components. For more mundane items, these might simply be basic materials such as metal or wood, while more advanced designs might require a perfect diamond or the blood of a dragon. Designs with more esoteric key components will have any common material requirements grouped under a generalised material cost, and are generally assumed available except for specific circumstances at the DM's discretion (e.g. the town has an iron metal shortage). Whether an ingredient can be purchased or must be found through adventuring is also at the DM's discretion. All ingredients are consumed upon completion. If the crafting process is interrupted or ended prematurely, the ingredients are not lost.

Crafting Time The time required to create the item. A creature can spend up to 8 hours a day crafting an item. If multiple creatures are working on an item, then the crafting time is divided by the number of creatures that have at least one of the required tool proficiencies. A project can be suspended if needed, but can't be resumed if any requirements are later unfulfilled.
