You can fight with a weapon wielded in each of your hands. You can make one extra attack each round with the secondary weapon.

Prerequisite: Dex 15.

Benefit: Your penalties on attack rolls for fighting with two weapons are reduced. The penalty for your primary hand lessens by 2 and the one for your off hand lessens by 6. See the table below:

Circumstances Primary Hand Off Hand
Normal Penalties -6 =10
Off-hand weapon is a light weapon -4 -8
Two-Weapon Fighting feat -4 -4
Off-hand weapon is a light weapon and Two-Weapon Fighting feat -2 -2

Normal: If you wield a second weapon in your off hand, you can get one extra attack per round with that weapon. When fighting in this way, you suffer a -6 penalty with your primary hand and a -10 penalty with your off hand. If your off-hand weapon is a finesse weapon, the penalties are reduced by 2 each. An unarmed strike is always considered a finesse weapon.
