Skill in crafting, and the associated tools, help you make specialized ability checks, craft certain items, or both.
Ability. This entry lists the ability to use when making an ability check with the tool.
Utilize. Examples of things you can do with the tool when you take the Utilize action. You can do one of those things each time you take the action. This entry also provides the DC for the action.
Craft. This entry lists what, if anything, you can craft with the tool.
Variants. This entry appears if the tool has variants, which are listed. Each requires a separate proficiency. (For example, proficiency with a Lute, does not grant you proficiency with a Viol.)
Tool & Skill Proficiency
If you have proficiency with a Tool Kit, add your Proficiency Bonus to any ability check you make that uses the tool.
If you have proficiency in a Crafting Skill that’s used with that check, you have Advantage on the check as well.
Example: a musician with proficiency in the performance skill, and their instrument adds their proficiency bonus and rolls with advantage.
If you use an Artisan Tool you are not proficient with, you make the roll with Disadvantage.
To craft an item, you must have the appropriate Tool Kit in your inventory.
Toolkit and Crafting Syngeries
Adventurers can combine their proficiencies to craft items or tackle complex problems together.
For example, a character proficient in Woodcarving might craft arrow shafts that another character—skilled in Fletching—can turn into finished arrows.
A player with a Forgery Kit could partner with someone proficient in Calligraphy to produce a highly convincing invitation, or collaborate with a Book Binding expert to fabricate an entire false historical text.
