The skill name line includes (in addition to the name of the skill) the following information.
Trained Only: If this notation is included in the skill name line, you must have at least 1 rank in the skill to use it. If it is omitted, the skill can be used
untrained (with a rank of 0). If any
special notes apply to trained or
untrained use, they are covered in the
Untrained section (see below).
Armor Check Penalty: If this notation is included in the skill name line, an
armor check penalty applies (when appropriate) to checks using this skill. If this entry is absent, an
armor check penalty does not apply.
The skill name line is followed by a general description of what using the skill represents. After the description are a few other types of information:
Action: The type of
action using the skill requires, or the amount of time required for a
check.
Try Again: Any
conditions that apply to successive attempts to use the skill successfully. If the skill doesn't allow you to attempt the same task more than once, or if failure carries an inherent penalty (such as with the
Climb skill), you can't take 20. If this paragraph is omitted, the skill can be retried without any inherent penalty, other than the additional time required.
Special: Any extra facts that apply to the skill, such as
special effects deriving from its use or bonuses that certain characters receive because of class, feat choices, or race.
Synergy: Some skills grant a bonus to the use of one or more other skills because of a synergistic effect. This entry, when present, indicates what bonuses this skill may grant or receive because of such synergies. See Table 4-5 for a complete list of bonuses granted by
synergy between skills (or between a skill and a class feature).
Restriction: The full utility of certain skills is restricted to characters of certain classes or characters who possess certain feats. This entry indicates whether any such restrictions exist for the skill.
Untrained: This entry indicates what a character without at least 1 rank in the skill can do with it. If this entry doesn't appear, it means that the skill functions normally for
untrained characters (if it can be used
untrained) or that an
untrained character can't attempt checks with this skill (for skills that are designated as "
Trained Only").
