Some
skill applications require the use of tools. If tools are needed, the specific items required are mentioned in the
skill description. If the character doesn't have the appropriate tools, he or she can still attempt to use the
skill, but the character takes a -4 penalty on his or her check.
A character may be able to put together some impromptu tools to make the check. If the GM allows it, reduce the penalty to -2 (instead of -4) for using impromptu tools. It usually takes some time (several minutes to an hour or more) to collect or create a set of impromptu tools, and it may require a
skill check as well.
