Star Wars: Knights of the Old Republic Wiki

Attributes represent the characters natural-born talents. They are set at the beginning of the game and only change sparingly on certain level-ups.

All attributes have modifiers to them, which are added to equations in combat, skills, and your maximum Vitality and Force. This modifier is increased by 1 when the attributes value is increased by 2.

Attributes Description
Strength (Str) Represents physical power. A high Strength adds modifiers to melee damage and chance to hit, which is important for characters who use close-combat weapons (vibroblades, lightsabers).
Dexterity (Dex) Represents agility and reflexes. A high Dexterity adds modifiers to ranged attack rolls (blasters) and increases a character's Defense rating, making them harder to hit.
Constitution (Con) Represents health and resiliency. A high Constitution adds modifiers to the vitality points gained at each level up. This is important for all characters and classes, but essential for soldiers and Jedi guardians.
Wisdom (Wis) Represents willpower and perception. A high Wisdom adds modifiers to Jedi Force points and Force power saving throws. The Force powers of a Jedi with high Wisdom are also much harder to resist.
Intelligence (Int) Represents knowledge and reasoning. A high Intelligence adds modifiers to the number of points a character has to spend on essential skills.
Charisma (Cha) Represents personality and the ability to lead. A high Charisma adds modifiers to Force-related feats and powers that are very important to all the Jedi classes. A higher Charisma decreases the penalty for a light-side character using dark-side powers, and vice-versa. It is also central to any persuasive talker.
