Ok, I know this seems like it should be something pretty basic.
I have been playing for a long time that with two weapon fighting it just gives you an extra off-hand attack.
It says: You can make one extra attack each round with the second weapon.
I thought that was pretty straight forward until a read the rules of the game web page on the wizards website. In the two weapon fighting rules it says you can make the extra attack when you make a full attack action.
I just read the combat section in players handbook and it does say -
Multiple Attacks: A character who can make more than one
attack per round must use the full attack action (see Full-Round
Actions, below) in order to get more than one attack.
I guess I never interpreted that to mean it took a full attack action since the feat description doesn't say anything about it.
Thanks.
