wow, the falmer creep me out. as soon as i see one of those guys, i turn the fnck around and get outta there.
You shouldn't, they're cannon fodder. They drop quite a bit of gold, too. They're blind, but apparently being unable to see didn't cause an uptick in their other senses, because they just can't seem to detect you at all. I'm thief spec'd, so your mileage may vary, but I was able to sneak around directly in front of them without being spotted.
You can snipe them to your hearts content, pretty much. They aren't fast, and you should be able to drop them all long before they even get an inkling of where you might be. If they get on you, they still shouldn't be much worry; my thief held his own against 2 at a time. Any more than that and they might be a danger to you, but that's a relatively easy situation to avoid. They're good money, and I built up a lot of sneak skill around them. I wasn't nearly as thief-y when I first started dealing with them.
As part of the thief quest you run into stronger versions of them in large groups, and those are parts when I'd say it's advisable (and pretty darn easy) to sneak past them. Edited, Nov 28th 2011 10:40am by Eske
