The Wererats
 
    The Wererats are more dangerous than they look.  They aren't actually all that tough to kill if you have the right weapons - Silver weapons.  There are a number of silver weapons scattered throughout the game, one of the most effective being the +1 Silver Great-axe of the Hobgoblin chief Kluugar.  This will be a most effective weapon against undead and shapeshifters.  If you don't have silver weapons, then at least have magic weapons that you can enchant - each additional "+" gives them another 1-6 damage of whatever enchantment type they are carrying.  Magical weapons are better than nothing, but silver weapons are best.  There is also a silver spetum, and a silver scimitar that you should have before you meet the Wererats.  You might also get good items at the merchants and be able to steal or buy some silver weapons.
