Two-Weapon Fighting, Perfect (Feat)
Benefit: Any character can wield two weapons (even without this feat), and doing so allows the wielder to perform an extra attack with their first attack (and only their first attack) of a full attack action. When dual-wielding, a character suffers penalties to all of their to-hit values for all attacks they perform with their main hand, as well as the extra attack they make with their off-hand, due to the difficulty of swinging around two weapons at once. Characters who take this feat can reduce these penalties to a more manageable level (but not eliminate them entirely). Penalties for dual-wielding apply to all attacks the character makes until the start of their next turn (including any attacks of opportunity they perform). A character can avoid these penalties by choosing not to perform the extra attack with their off-hand weapon in a given round.
While your full attack likely grants you more than one attack with your main hand, you can never perform more than one attack with your off-hand weapon (unless you also take one or more of the advanced two-weapon fighting feats, such as Improved Two-Weapon Fighting).
The extra attack with your off-hand weapon uses your highest to-hit roll (since it is made as part of the first attack of your full attack action), but is adjusted for the particular to-hit bonuses of your off-hand weapon, as well as the penalty for dual-wielding. As a result, it can be different from the to-hit value with your primary weapon. Similarly, damage calculations for your off-hand weapon are rolled separately, and are based on that weapon, not your primary weapon.
The extra attack with the off-hand weapon can be made against the same target you attack with your main hand, or a different target within reach.
Because the extra attack with your off-hand weapon is considered part of the first attack of your full attack action, anything that causes you to lose or use up your first attack of your full attack action (such as a Charge maneuver) would also prevent you from gaining this extra attack with your off-hand.
