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. Your race, class, background, or feats give
you proficiency with certain tools. Proficiency with a tool
allows you to add your proficiency bonus to any ability
check you make using that tool. Tool use is not tied to
a single ability, since proficiency with a tool represents
broader knowledge of its use. 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
