BG2 Expansion Pack Preview

The award for very first preview of the Throne of Bhaal, expansion pack to Baldur's Gate II, is up at Computer Games Online. It mainly deals with the storyline and a few of the new locations. Here's a brief:

There are a number of new spells and abilities in the expansion as well, including a new character kit, the Wild Mage. Miranda describes some of the spells that you'll be able to cast as "Biblical" in scale, similar to the Quest Spells introduced in the AD&D 2nd Edition Tome of Magic. Storm of Vengeance, for instance, creates a mass of purple clouds that have a chance to slay your enemies outright. After that, the clouds turn poisonous. Then they rain down fire and acid. Then they shoot out a bit of lighting here and there, just to mop up anyone that might still be standing.

I've got two questions about the game. One, is there anywhere in the rules that has actual charts and spell progression for characters past level, say 25? Second, are they going to strip us of our "Cloak of Mirrors"? Imagine having complete resistance to offensive spells and also being level 40.
