Skills

Skills represent your character’s aptitude outside of combat. Sneaking your way past a group of guards, recalling knowledge about an ancient civilization, and making a leap across a large chasm are all accomplished through the use of skills. As your character advances in level, he can gain new skills and improve his existing skills dramatically.

Acquiring Skills

Each level, your character gains a number of skill ranks dependent upon your class plus your Intelligence modifier. Investing a rank in a skill represents a measure of training in that skill. You can never have more ranks in a skill than your total number of Hit Dice. In addition, each class has a number of favored skills, called class skills. It is easier for your character to become more proficient in these skills, as they represent part of his professional training and constant practice. You gain a +5 bonus on all class skills that you put ranks into. If you have more than one class and both grant you a class skill bonus, these bonuses do not stack.
The number of skill ranks you gain when gaining a level is dependent on the class in which you level up in. Humans gain 1 additional skill rank per class level. Characters who take a level in a favored class have the option of gaining 1 additional skill rank or an additional hit point. If you select a level in a new class, all of its class skills are automatically added to your list of class skills, and you gain a +5 bonus on these skills if you have ranks in them.

Skill Checks

When your character uses a skill, he isn’t guaranteed success. In order to determine success, whenever you attempt to use a skill, you must make a skill check. Each skill rank grants a +1 bonus on checks made using that skill. When you make a skill check, you roll 1d20 and then add your ranks and the appropriate ability score modifier to the result of this check. If the skill you’re using is a class skill (and you have invested ranks into that skill), you gain a +5 bonus on the check. If you are not trained in the skill (and if the skill may be used untrained), you may still attempt the skill, but you use only the bonus (or penalty) provided by the associated ability score modifier to modify the check. Skills can be further modified by a wide variety of sources—by your race, by a class ability, by equipment, by spell effects or magic items, and so on. If the result of your skill check is equal to or greater than the difficulty class (or DC) of the task you are attempting to accomplish, you succeed. If it is less than the DC, you fail. Some tasks have varying levels of success and failure depending on how much your check is above or below the required DC. Some skill checks are opposed by the target’s skill check. When making an opposed skill check, the attempt is successful if your check result exceeds the result of the target.

Taking 10 and Taking 20

A skill check represents an attempt to accomplish some goal, usually while under some sort of time pressure or distraction. Sometimes, though, a character can use a skill under more favorable conditions, increasing the odds of success.

<php>echo “<b>Taking 10:</b>”;</php> When your character is not in immediate danger or distracted, you may choose to take 10. Instead of rolling 1d20 for the skill check, calculate your result as if you had rolled a 10. For many routine tasks, taking 10 makes them automatically successful. Distractions or threats (such as combat) make it impossible for a character to take 10. In most cases, taking 10 is purely a safety measure—you know (or expect) that an average roll will succeed but fear that a poor roll might fail, so you elect to settle for the average roll (a 10). Taking 10 is especially useful in situations where a particularly high roll wouldn’t help.

<php>echo “<b>Taking 20:</b>”;</php> When you have plenty of time, you are faced with no threats or distractions, and the skill being attempted carries no penalties for failure, you can take 20. In other words, if you a d20 roll enough times, eventually you will get a 20. Instead of rolling 1d20 for the skill check, just calculate your result as if you had rolled a 20.
Taking 20 means you are trying until you get it right, and it assumes that you fail many times before succeeding. Taking 20 takes 20 times as long as making a single check would take (usually 2 minutes for a skill that takes 1 round or less to perform).
Since taking 20 assumes that your character will fail many times before succeeding, your character would automatically incur any penalties for failure before he or she could complete the task (hence why it is generally not allowed with skills that carry such penalties). Common “take 20” skills include Thievery (when used to open locks), Acrobatics (when used to escape from restraints), and Perception (when attempting to find traps).

<php>echo “<b>Ability Checks and Caster Level Checks:</b>”;</php> The normal take 10 and take 20 rules apply for ability checks. Neither rule applies to concentration checks or caster level checks.

Aid Another

You can help someone achieve success on a skill check by making the same kind of skill check in a cooperative effort. If you roll a 10 or higher on your check, the character you’re helping gets a +2 bonus on his or her check. (You can’t take 10 on a skill check to aid another.) In many cases, a character’s help won’t be beneficial, or only a limited number of characters can help at once.
In cases where the skill restricts who can achieve certain results, such as trying to open a lock using Thievery, you can’t aid another to grant a bonus to a task that your character couldn’t achieve alone. The DM might impose further restrictions to aiding another on a case-by-case basis as well.

Skill Descriptions

This section describes each skill, including common uses and typical modifiers. Characters can sometimes use skills for purposes other than those noted here, at the DM’s discretion. Skill descriptions adhere to the following guidelines.

<php>echo “<b>Skill Name:</b>”;</php> The skill name line includes (in addition to the name of the skill) the following information.
<php>echo “<i>Key Ability:</i>”;</php> The abbreviation of the ability whose modifier applies to the skill check.
<php>echo “<i>Armor Check Penalty:</i>”;</php> If this notation is included in the skill name line, an armor check penalty applies to checks using this skill. If this entry is absent, an armor check penalty does not apply.

<php>echo “<b>Description:</b>”;</php> The skill name line is followed by a general description of what using the skill represents.

<php>echo “<b>Subskill Name:</b>”;</php> The name of the subskill, followed by a brief description. Each subskill is accompanies by the following information.
<php>echo “<i>Trained Only:</i>”;</php> If this notation is included in the skill name line, the skill must be a class skill for you, and you must have at least 1 rank in the skill to use it. If this notation 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).
<php>echo “<i>Check:</i>”;</php> What a character (“you” in the skill description) can do with a successful skill check and the check’s Difficulty Class (DC).
<php>echo “<i>Action:</i>”;</php> The type of action using the skill requires, or the amount of time required for a check.
<php>echo “<i>Try Again:</i>”;</php> 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 Athletics 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.
<php>echo “<i>Special:</i>”;</php> 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.
<php>echo “<i>Restriction:</i>”;</php> The full utility of certain skills is restricted to characters of certain classes. This entry indicates whether any such restrictions exist for the skill.
<php>echo “<i>Untrained:</i>”;</php> 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 “Trained Only”).


Acrobatics (Dex)

<php>echo “<i>Armor Check Penalty</i>”;</php>

You can perform an acrobatic stunt, keep your balance while walking on narrow or unstable surfaces, slip free of a grab or restraints, maneuver through a foe’s space in combat, or take less damage from a fall.

Acrobatic Stunt

You can make daring acrobatic maneuvers and feats of great agility.
<php>echo “<b>Check:</b>”;</php> You can use an Acrobatics check to swing from a chandelier, somersault over an opponent, slide down a staircase on your shield, or attempt any other acrobatic stunt that you can imagine and that your DM agrees to let you try. The DM sets the DC based on the complexity of the stunt and the danger of the situation. If the stunt fails, you fall prone in the square where you began the stunt (the DM might change where you land, depending on the specific stunt and situation). Your DM always has the right to say that a stunt won’t work in a particular situation or to set a high DC.
<php>echo “<b>Action:</b>”;</php> Performing an acrobatic stunt is a standard or move action, depending on the stunt.

Balance

You can keep your balance while walking on a tightrope, a narrow beam, a slippery ledge, or an uneven floor.
<php>echo “<b>Check:</b>”;</php> You can use Acrobatics to move on narrow surfaces and uneven ground without falling. A successful check allows you to move at half speed across such surfaces—only one check is needed per round. Use the following table to determine the base DC. While you are using Acrobatics in this way, you are considered flat-footed and lose your Dexterity bonus to your AC (if any). If you take damage while balancing, you must immediately make another Acrobatics check at the same DC to avoid falling or being knocked prone.

Surface Width Acrobatics DC
Greater than 3 feet wide 0*
1-3 feet wide 5*
7-11 inches wide 10
2-6 inches wide 15
less than 2 inches wide 20

*No Acrobatics check is needed to move across these surfaces unless the modifiers to the surface increase the DC to 10 or higher.

Many conditions can affect your chances of success with Acrobatics checks made to balance. The following modifiers to target DCs apply to all balance checks. The modifiers stack with one another, but only the most severe modifier for any one condition applies.

Balance Modifiers DC Modifier
Slightly obstructed (gravel, sand) +2
Severely obstructed (cavern, rubble) +5
Slightly slippery (wet) +2
Severely slippery (ice) +5
Slightly sloped (<45º) +2
Severely sloped (>45º) +5
Slightly unsteady (boat in rough water) +2
Moderately unsteady (boat in a storm) +5
Severely unsteady (earthquake) +10

<php>echo “<i>Accelerated Movement:</i>”;</php> You can try to walk across a precarious surface more quickly than normal. If you accept a -5 penalty, you can move your full speed as a move action. (Moving twice your speed in a round requires two Acrobatics checks, one for each move action used). You may also accept this penalty in order to charge across a precarious surface; charging requires one Acrobatics check for each multiple of your speed (or fraction thereof) that you charge.
<php>echo “<b>Action:</b>”;</php> None. A balance check doesn’t require an action; it is made as part of another action or as a reaction to a situation.

Escape Artist

Your training allows you to slip out of bonds and escape from grapples.
<php>echo “<b>Check:</b>”;</php> The table below gives the DCs needed to escape various forms of restraints.
<php>echo “<i>Ropes:</i>”;</php> The DC of your Acrobatics check is equal to the binder’s Combat Maneuver Bonus +20.
<php>echo “<i>Manacles and Masterwork Manacles:</i>”;</php> The DC for manacles is set by their construction (see the table below).
<php>echo “<i>Tight Space:</i>”;</php> The DC noted is for getting through a space through which your head fits but your shoulders don’t. If the space is long, you may need to make multiple checks. You can’t squeeze through a space that your head does not fit through.
<php>echo “<i>Grappler:</i>”;</php> You can make an Acrobatics check in place of a combat maneuver check to escape a grapple, or to change from a pinned condition to merely grappled.
