Key Ability: The abbreviation for the ability whose modifier applies to the
skill check. Exceptions: Speak Language and Read/Write Language have "None" given as their
key ability because the use of these skills never requires a check.
Trained Only: If "
Trained Only" appears on the line beneath the skill name, a character must have at least 1 rank in the skill to use it. If "
Trained Only" is omitted, the skill can be used
untrained. If any particular notes apply to trained or
untrained use, they are covered in the
Special section (see below).
Try Again?: Any conditions that apply to repeated attempts to use the skill for a particular purpose. If this entry is omitted, the
skill check can be tried again without any inherent penalty other than taking additional
time.
Untrained: Any details about using a skill
untrained. If this entry doesn't appear, it means the skill works the same even when used
untrained, or that an
untrained character can't make checks with this skill (true for skills that are designated "
Trained Only").
