Two-Weapon Fighting

Two-weapon fighting reduces the to-hit penalty when using two weapons at the same time. The penalty for your primary hand lessens by 2 and the one for your off-hand lessens by 6, so it becomes -4 (main hand) / -4 (off-hand) (instead of -6/-10 without this feat). If the off-hand weapon is light, the penalties both decrease by another 2 points, down to -2/-2 (instead of -4/-8 without this feat).

After Update 5, an off-hand attack would have a chance to proc on any main hand attack now, instead of being predetermined on certain attacks. The default chance to proc an off-hand attack is 20%.

Two-weapon fighting increases the chance to proc an off-hand attack by 20%, bringing the total chance to 40%.

Having more TWF feats increases the % chance of proccing an off-hand attack.

This feat also works for unarmed Monks, and has the same effect.

Prerequisite: Dex 15.

Special: A ranger automatically gains Two-Weapon Fighting at 2nd level, even if he does not have the prerequisite for it.

A fighter may select Two-Weapon Fighting as one of his fighter bonus feats.
