Skip to about 2:30.

might have to do with your character, weapons, and weapon skills/stats

Remember Daggerfall doesn't insist you have to kill everything and everybody. If you haven't got a weapon that will affect the imp,.son;t go into that room - walk straight past! One of the hardest creatures is the Skeleton, but Daggerfall gives you another route (should you wish to find it!) which allows you to bypass it!

For players not used to RPG's of the 90's, it takes quite a different thought process to go through. Note taking is required, for example, and things like weapon and creature research. Modern RPG's don't demand this of you and hand hold a lot more (for the console crowd that publishers believe have less patience - despite high sales for games like Fallout 3 and Oblivion on console!)
