Crafting

Rules for Crafting
Using an appropriate set of tools, a character can craft nearly any item imaginable. In order to do so, they must know the appropriate formula, supply the required Basic Ingredients and a potential Key Ingredient, and work in the required Location for the required Crafting Time. If all of these conditions are met the character will make a skill check with the requisite tool set, and if the given DC is met the item will be successfully crafted. If the DC is not met the creation fails, and as a result the character loses any Key Ingredients that were used and half of the Basic Ingredients.

Basic Ingredients
In order to craft any item, mundane or magical, some amount of Basic Ingredients are necessary. Basic Ingredients are measured in gold pieces and each unique set of tools requires its own matching category of Basic Ingredients (e.g. Basic Ingredients(Alchemy), Basic Ingredients(Woodworking), etc.).

Key Ingredients
Some formulas require a Key Ingredient in addition to Basic Ingredients. These items are typically magical in nature. Key Ingredients include spells, plants, monster essence, potions, and rare metals.

Spells
Formulas that have a spell as a Key Ingredient requires the character to cast the requisite spell during the crafting process, including expending a spell slot and having the spell prepared (when applicable). The spell may be cast from a spell scroll, but another creature cannot cast the spell for the crafter. Some formulas may require the spell to be cast at a higher level than its base level.

Monster Essence
Formulas that have a Monster Essence as a Key Ingredient require some piece or part of a monster to be used in the crafting process. Essence may range from the liver of a goblin to shavings from a dragon's horn. Higher Potency items may require the Essence come from a higher Challenge Rating (CR) monster than the base formula. Unless otherwise specified, Essence from Beasts, Constructs, and Humanoids cannot be used as Key Ingredients, Additionally, Essence can usually only be harvested from a dead monster, unless otherwise specified. Only a single Essence can be harvested from a monster unless otherwise determined by the DM.

Crafting Time
Every formula has a required crafting time. This is the time a character is required to spend working on a particular item. During this time the character must focus all of their attention on the task at hand, taking only rare breaks to eat and rest. Unless otherwise specified an item must be constructed in one sitting, without breaking the Crafting Time into smaller increments.

Location
Each formula has a required location, during the crafting process, a character is required to remain in this location for the entire Crafting Time.

Workshop
The character must remain in a specialized room or small building for the duration of the Crafting Time. A character may set up their own Workshop, pay to rent one for a period of time, or get permission to use another creature's Workshop. Workshops are permanent locations. Examples, forging a weapon or brewing a powerful potion.

Fixed
The character must remain in the same location for the duration, working with only their tools and ingredients. Unlike a Workshop, a character may begin working on a Fixed formula anywhere in the world, but must remain in that location for the duration. Examples, mixing an elixir or sharpening a sword.

Mobile
The character can move and travel while they work. So long as the character does not take damage and is traveling at a Normal pace or slower, they may work while they travel, though they must have both hands free. Examples, whittling a piece of wood or repairing a bowstring.

Potency
Some formulas are separated into different Potencies. The better ingredients used and the more skill a character possesses, the higher Potency a crafted item will have.Higher Potencies may make a potion's effects last longer, a weapon deal more damage or an enchantment have a greater effect. Different Potencies may have their own Basic Ingredients cost, Key Ingredients, Crafting Time, and required Location, but they share the same basic formula.

Whenever you attempt to craft an item, the result is of the highest Potency for which the character meets all of the requirements.

If you attempt to create a higher Potency item and fail, creating a weaker variety instead, you only lose the amount of Basic Ingredients required for the version you successfully created.

Tool Sets
Each set of tools available to a character enables them to craft different types of items. Each tool set is described below.

Alchemist's Supplies
Alchemist's Supplies are used to create magical potions and oils. Potions created using Alchemy tend to be stronger and more valuable than Elixirs created using Herbalism, however, the ingredients used to create them are also more rare and expensive. Alchemy Formulas use Monster Essences and Spells as Key Ingredients. The full rules for Alchemy can be found here.

Herbalism Kit
An Herbalism Kit is used to create Elixirs. Elixirs are brewed using plants with latent magical properties. Elixirs are similar to Alchemical Potions but tend to be slightly weaker. However, the herbs needed to create Elixirs are also far more plentiful than the ingredients needed for Alchemy. Herbalism Formulas use Plants as Key Ingredients. The full rules for Herbalism can be found here.

Poisoner's Kit
The Poisoner's Kit is used to brew Poisons of various strengths. The creation and trade of Poisons are outlawed in most civilized nations, and heavily regulated in those that allow it. Poison Formulas use Spells, Monster Essence, and Plants as Key Ingredients. The full rules for Poisons can be found here.

Smith's Tools
Smith's Tools are used to forge various items, mostly weapons and armor, from metal. The items crafted using Smith's Tools vary greatly and may range from a simple door hinge to Masterworked Adamantine Armor. Smithing Formulas require Metals as a Key Ingredient. The full rules for Smithing can be found here.

Spellsmith's Tools
Using Spellsmith's Tools a character can forge powerful magic items. Spellsmithing Formulas require Spells and Oils as Key Ingredients. The full rules for Spellsmithing can be found here.
