Two-Weapon Fighting

Type: General
Source: Player's Handbook v.3.5

You can fight with a weapon in each hand. You can make one attack each round with the second weapon.

Benefit: Your penalties for fighting with two weapon are reduced by 2.
Special: The Ambidexterity feat reduces the attack penalty for the second weapon by 4. A ranger wearing light armor or no armor can fight with two weapons as if he had the feats Ambidexterity and Two-Weapon Fighting.
For Spell Casters: You can use a touch spell as part of a two-weapon attack. You must already have a weapon in one hand while casting the touch spell, hold the charge, and then attack with both spell and weapon during a later action. If you cast the spell and then draw weapon, the spell discharges and is wasted.
The hand used to deliver the touch spell is considered a light weapon and uses the appropriate attack modifiers.
