A tool such as a forgery kit is used to make fake objects and little else. The History skill applies to any event in the past. Tools have more specific applications than skills. This section offers various ways that tools can be used in the game. At the game table, though, the use of tools sometimes overlaps with the use of skills, and it can be unclear how to use them together in certain situations.
Tool proficiencies are a useful way to highlight a character's background and talents. Proficiency with these tools lets you add your proficiency bonus to any ability checks you make to disarm traps or open locks. This set of tools inc1udes a small file, a set of lock picks, a small mirror mounted on a metal handle, a set of narrow-bladed scissors, and a pair of pliers. For example, the DM might ask you to make a Dexterity check to carve a fine detail with your woodcarver's tools, or a Strength check to make something out of particularly hard wood. Tool use is not tied to a single ability, since proficiency with a tool represents broader knowledge of its use. Proficiency with a tool allows you to add your proficiency bonus to any ability check you make using that tool. Your race, class, background, or feats give you proficiency with certain tools.
A tool helps you to do something you couldn't otherwise do, such as craft or repair an item, forge a document, or pick a lock.
