Is it possible to get functional Moonblades in the game? I heard you could on another board. I found one, but it's a miscellaneous item that doesn't count as an actual sword. Any comments on this?

There are no moonblades in this game, except the one you get in Sul... Sulsa... uh... Suldanesselar? That elven city. And that one can't be used. Actually, that's a lie. Technically the moonblade that Xan owned in BG1 is in the game, but only Xan can use that one.
