NWN lacks a lot from the original Dnd. Here it's the ability to wield any weapon with two hands, thereby getting the 1,5x strength modifier to AB and damage. In NWN, you can only get that from large two-handed weapons, while it should have been like, that if you had for example a longsword in you right hand, and nothing in your left hand, you would automatically wield the sword with both hands...They have that in Knights of the Old Republic, if anyone here has tried it...
