Downtime

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.
Practicing a Profession You can work between adventures, allowing you to maintain a modest lifestyle without having to pay 1 gp per day. This benefit lasts as long you continue to practice your profession.
If you are a member of an organization that can provide gainful employment, such as a temple or a thieves' guild, you earn enough to support a comfortable lifestyle instead.
If you have proficiency in the Performance skill and put your performance skill to use during your downtime, you earn enough to support a wealthy lifestyle instead.
Researching The time between adventures is a great chance to perform research, gaining insight into mysteries that have unfurled over the course of the campaign. Research can include poring over dusty tomes and crumbling scrolls in a library or buying drinks for the locals to pry rumors and gossip from their lips.
When you begin your research, the GM determines whether the information is available, how many days of downtime it will take to find it, and whether there are any restrictions on your research (such as needing to seek out a specific individual, tome, or location). The GM might also require you to make one or more ability checks, such as an Intelligence (Investigation) check to find clues pointing toward the information you seek, or a Charisma (Persuasion) check to secure someone's aid. Once those conditions are met, you learn the information if it is available.
For each day of research, you must spend 1 gp to cover your expenses. This cost is in addition to your normal lifestyle expenses.
Training You can spend time between adventures learning a new language or training with a set of tools. Your GM might allow additional training options.
First, you must find an instructor willing to teach you. The GM determines how long it takes, and whether one or more ability checks are required.
The training lasts for 250 days and costs 1 gp per day. After you spend the requisite amount of time and money, you learn the new language or gain proficiency with the new tool.
Scribing Spell Scrolls With time and patience, a spellcaster can transfer a spell to a scroll, creating a spell scroll.
Resources. Scribing a spell scroll takes an amount of time and money related to the level of the spell the character wants to scribe, as shown in the Spell Scroll Costs table. In addition, the character must have proficiency in the Arcana skill and must provide any material components required for the casting of the spell. Moreover, the character must have the spell prepared, or it must be among the character’s known spells, in order to scribe a scroll of that spell.
If the scribed spell is a cantrip, the version on the scroll works as if the caster were 1st level.

Alchemy With time, patience and the right reagents, a alchemist can create potions.
Resources. Brewing a potion takes an amount of time and money related to the level of the potion the character wants to brew, as shown in the Potions table. In addition, the character must have proficiency herbalism kit and must provide any material components required for the potion. Moreover, the character must have a recipe for the potion or know someone that can teach them the recipe.
