Traps are not much of a surprise in Skyrim the more you play Skyrim. Traps can deal a lot of damage and it is best to stay clear from them when your health is very low. Sometimes I save traps for some of the tougher enemies that might be ahead of any barrow, fortress, etc. Traps like spiked gates, swinging axes, flammable liquid, and others do a good amount of damage. Sometimes its easy to lead enemies to their traps. Most times, draughs run into their own traps, even death draughs and maybe a dragon priest. In one of my playthroughs of Skyrim, there was one death draugh that tried walking through a set of swinging axes and failed and one dragon priest that set off a swinging log trap that defeated him. Nothing is wrong with using traps to defeat your enemies, even if you have good weapons, armor, etc.. Have you used traps to take care of a group of enemies before?
