On the question of the Nishruu - you have to be careful with them, as they can destroy magic items.
If they are set against you, they can destroy magic items on your characters (for example I lost a recently acquired Robe of Good Archmagi this way) or if you set one against an enemy it can destroy items you may want to pick up when they're dead.
So be careful before you use the Nishruu spell!!!
