Star Wars: Knights of the Old Republic/Feats

Two-Weapon Fighting
Two-Weapon Fighting reduces the penalties incurred for using a double-bladed weapon or for dual-wielding (one weapon in each hand). Normal penalties are -6/-10 (dominant hand/off hand). This feat reduces the penalty to -6/-6. Using a "balanced" weapon with this feat reduces the penalty to -4/-6.

There are three tiers for this feat allowing the character to become better at dual-wielding and using two-handed weapons.

Improved Two-Weapon Fighting
The second-tier feat Improved Two-Weapon Fighting reduces the penalties incurred for using a double-bladed weapon or for dual-wielding even more. This feat reduces the penalty to -4/-4. Using a "balanced" weapon with this feat reduces the penalty to -2/-4.
 * Prerequisites:
 * Two-Weapon Fighting
 * Character level 4

Master Two-Weapon Fighting
The third-tier of the Two-Weapon Fighting suite, Master Two-Weapon Fighting heavily reduces the penalties incurred for using a double-bladed weapon or dual-wielding. This feat reduces the penalty to -2/-2. Using a "balanced" weapon with this feat reduces the penalty to 0/-2, almost completely removing the penalty.
