Tools

Tools and kits allow your character to perform tasks that would otherwise seem impossible. Some of these kits relate to backgrounds that your character may have had before they started adventuring.
Proficiency with a tool allows you to add your proficiency bonus to the check. Tools do not have a mandatory ability score associated with them. Instead, this book will suggest a certain ability score to use with it, depending on the task you are trying to do. The Dungeon Master may ask of a certain ability score to be used. When doing so, you may apply your ability score modifier to the roll.
