Skills

Your character's skills represent a variety of abilities, and you get better at them as you go up in level. A skill check takes into account your training (trained skill bonus), natural talent (ability modifier), and luck (the die roll). It may also take into account your species' knack for certain skills or the armor you're wearing (armor check penalty), among other things.

Trained Skills vs. Untrained Skills

When you make a character, you are allowed to select a number of skills as trained skills. Your character receives a number of trained skills based on his or her character class and Intelligence modifier (minimum of 1 trained skill). Trained skills are selected from the character's list of class skills at 1st level, and a character may acquire new trained skills by taking the Skill Training feat. The major difference between a trained and an untrained skill is that you gain a +5 bonus on skill checks if you're trained in the skill. However, some skills (such as Use the Force) can't be used untrained.

Class Skills

Jedi	2 + Int modifier	Acrobatics, Athletics, Endurance, Initiative, Knowledge (all skills, taken individually), Mechanics, Perception, Pilot, Use the Force
Noble	6 + Int modifier	Deception, Gather Information, Initiative, Knowledge (all skills, taken individually), Perception, Persuasion, Pilot, Ride, Treat Injury, Slicing
Scoundrel	4 + Int modifier	Acrobatics, Deception, Gather Information, Initiative, Knowledge (all skills, taken individually), Mechanics, Perception, Persuasion, Pilot, Stealth, Slicing
Scout	5 + Int modifier	Athletics, Endurance, Initiative, Knowledge (all skills, taken individually), Mechanics, Perception, Pilot, Ride, Stealth, Survival
Soldier	3 + Int modifier	Athletics, Endurance, Initiative, Knowledge (tactics), Mechanics, Perception, Pilot, Treat Injury, Slicing

Using Skills

To make a skill check, roll:

1d20 + one-half your character level + key ability modifier + miscellaneous modifiers

If you are trained in the skill, add +5 to the skill check result.

A skill check is made just like an attack roll or a saving throw. The higher the roll, the better. You're either trying to get a result that equals or exceeds a certain Difficulty Class (DC), or you're trying to beat another character's check result. For instance, to sneak quietly past a guard, you need to beat the guard's Perception check with a Stealth check.

When adding "one-half your character level", always round down (a 1st-level character adds +0).

The "key ability modifier" is the character's bonus or penalty for the skill's associated ability (Strength, Dexterity, Constitution, Intelligence, Wisdom, or Charisma). The key ability of a skill is noted in its description.

"Miscellaneous modifiers" include armor check penalties and bonuses provided by talents, feats, or equipment.

Some skills can't be used untrained. These skills are noted on the Master Skill List. If your character is not trained in these particular skills, you are not allowed to make any kind of check with them.
