Crafting

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).
  Additionally, there are plenty of crafting options.
