How did you deal with them? Also, did you encounter a creature that does not normally reside in the area?

Ha!! Found it,,, the 3rd worg for quest credit,,AND....... a Dracolisk!!! I had Imoen scouting ahead and she saw it. I pulled her back to the party and thought awhile... ( I know nothing about this creature. Can it petrify? It's a cross between a black dragon and a basilisk. What does that tell me? What is a black dragon's weapon? Poison? I don't remember! Well,,, let's try...)
So I cast Gaze Reflection and Protection from Poison on Imoen, had her Hide In Shadows, had her creep ahead and intiate combat. The dracolisk focused on Immy and attacked(buggers move fairly fast!). Immy took some sort of gaze or breath attack that took half her hit points but didn't stop her. The dracolisk was then surrounded by my melee fighters and they made short work of it, with not too much damage.
General impressions: MUCH weaker than a dragon, of course, but also weaker than a normal basilisk it seemed to me. Maybe I just got lucky and had a few critical hits. Also after the dracolisk shot its weapon at Imoen(what is the monsters weapon?) it didn't try a ranged attack again and just proceeded to close to melee. I liked its slightly faster speed, but maybe it needs something like a poison bite to make it more formidable.
