Yeah. You remember all those other paths with all those oh-SO-lovely traps that absolutely murder you (the first time around, anyway)? Those are happy happy places. And remember all those potions you've been finding throughout the whole game and never used? This is a good place to drink, oh, half of them.

And if you're already out of Candlekeep, forget about finding the Halberd+2. It was on one of the bosses on the top floor of the Iron Throne. It's decayed into thin air by now. Sorry.
