That is true, yes. I don't think there's any way to finagle it into being worthwhile in the rules as they are. Fighting with a sword and dagger was something actually done in real life, as opposed to fighting with two swords like Drizz't does - but the dagger in this situation was a defensive weapon, not an offensive one. Which Salvatore didn't know or disregarded when he wrote Entreri.
