DProject: Got Branwen from the carnival, I think I now have a party I'm satisfied with, though there's still room for one more. I think I'll manage with just five people though. Just one more question: I found a Magic Missile wand, does it ever run out of missiles? I gave that to Branwen, might as well let her use it full-time if the wand never runs out. It doesn't show any number though, so I guess it has unlimited uses?
It can hold up to 100 charges, but how many it actually has when you find it depends on where you were. Once you use the last charge, it'll be destroyed. Unfortunately, in the base BG1 engine there's no display of how many charges it has, so you won't know to recharge it until it's too late. You can view or edit the charge amount in Dalekeeper of Near Infinity, or you could just keep an eye on it and reload if it's destroyed. To recharge it, just sell it to a vendor and then buy it right back; it'll be at max charges then.
Pangaea666: About respawning at the Gnoll stronghold. I read somewhere that when you save some creatures respawn there. First time I played I didn't know that, and saved all the time, as I always do. So there were piles and piles upon gnolls and such everywhere. Next time I played it without saving once, and there were considerably less. So there is something to that. You probably saved in between, and then they respawned. I agree it's a bit silly when you have already cleared it out, but it's free XP ;)
They'll respawn as soon as there isn't anyone within visible range of the spawn point. If you load the area a bunch of times, every out-of-sight spawn point will create more dudes every time you load, so you can get huge mobs of 50+ gnolls where there were only supposed to be 5. You can avoid this by either reloading as little as possible, or you can put a character next to the spawn point that's bothering you and just leave them there while the rest of your party explores. As long as they're nearby, that point won't make any more monsters. This is pretty useful in the gnoll stronghold because it's so twisty and turny, and it's even more useful in Firewine because you can drastically decrease the numbers of kobold archers you face.
