You can't go two minutes without running into an arachnid enemy in Skyrim. Found skulking in just about every dungeon you stumble into, these recurring nuisances wouldn't be so terrible if they didn't pack such a punch. While going up against one of these guys can be pretty easy if you know what you're doing, the likelihood that you'll end up swarmed and overwhelmed only grows higher with each and every encounter. So although a single one isn't going to do much to you if you cross it on the Dragonborn's travels, stumbling into a cave infested with these overgrown nightmares will have every arachnophobe instantly regretting their curious, adventurous ways.
