You can craft nonmagical objects, including adventuring equipment and works of art. You must be proficient with tools related to the object you are trying to create (typically artisan’s tools). You might also need access to special materials or locations necessary to create it. For example, someone proficient with smith’s tools needs a forge in order to craft a sword or suit of armor.
For every day of downtime you spend crafting, you can craft one or more items with a total market value not exceeding 5 gp, and you must expend raw materials worth half the total market value. If something you want to craft has a market value greater than 5 gp, you make progress every day in 5-gp increments until you reach the market value of the item. For example, a suit of plate armor (market value 1,500 gp) takes 300 days to craft by yourself.
Multiple characters can combine their efforts toward the crafting of a single item*, provided that the characters all have proficiency with the requisite tools and are working together in the same place. Each character contributes 5 gp worth of effort for every day spent helping to craft the item. For example, three characters with the requisite tool proficiency and the proper facilities can craft a suit of plate armor in 100 days, at a total cost of 750 gp.
While crafting, you can maintain a modest Lifestyle without having to pay 1 gp per day, or a comfortable lifestyle at half the normal cost (see chapter 5 for more information on lifestyle expenses).
Crafting an Item
A character who has the time, the money, and the needed tools can use downtime to craft armor, weapons, clothing, or other kinds of nonmagical gear.
Resources and Resolution.
In addition to the appropriate tools for the item to be crafted, a character needs raw materials worth half of the item's selling cost. To determine how many workweeks it takes to create an item, divide its gold piece cost by 50. A character can complete multiple items in a workweek if the items' combined cost is 50 gp or lower. Items that cost more than 50 gp can be completed over longer periods of time, as long as the work in progress is stored in a safe location.
Multiple characters can combine their efforts. Divide the time needed to create an item by the number of characters working on it. Use your judgment when determining how many characters can collaborate on an item. A particularly tiny item, like a ring, might allow only one or two workers, whereas a large, complex item might allow four or more workers.
A character needs to be proficient with the tools needed to craft an item and have access to the appropriate equipment. Everyone who collaborates needs to have the appropriate tool proficiency. You need to make any judgment calls regarding whether a character has the correct equipment. The following table provides some examples.
If all the above requirements are met, the result of the process is an item of the desired sort. A character can sell an item crafted in this way at its listed price.
