topic says it all. occasionally in dungeons you'll see pools of oil on the ground. if you use a flame spell it will ignite for big damage to anything standing in it. unfortunately my character does not use magic. he specializes in sneaking with bows and daggers and although my bow is enchanted with fire damage that does not count as far as igniting the oil

Shoot the vase-things that usually hang above the oil pools, thats what I do.

A lot of the time when there's oil pools, there are hanging lanterns that you can shoot down and they'll ignite the oil.

Alternatively, keep a fireball staff on your character.

It would be great if you could ignite it with a flame enchanted sword, though.

Pay no attention whatsoever to the hanging lanterns that look like they could be easily knocked down, especially at range by a single arrow.

Another? You mean like torches? Or like hanging lanterns? Maybe like the fire breath shout? How about THAT!

other then lanterns shouts and magic my flaming bow tends to set everything on fire if shot properly meaning arrow must stick in ground not lay there
