This section describes each skill, including common uses and typical modifiers. Characters can sometimes use skills for purposes other than those noted here.
Here is the format for skill descriptions.
The skill name line includes (in addition to the name of the skill) the following information.
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
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:
The type of action using the skill requires, or the amount of time required for a check.
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.
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: Skill Synergies for a complete list of bonuses granted by synergy between skills (or between a skill and a class feature).
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”).
