World of Warcraft has its fair share of spiders but as an arachnophobe I can deal with most as they are just crawling on the ground in plain sight, don't jump at you and are pretty much a mob like any other.
If you are a Necrolord and have your Anima Conductor upgraded to level 2 dailies will send you into Sightless Hold, a crypt under the House of Eyes, that you normally have no reason to go.
Have your camera panned down and everything is fine and dandy. Some spiders running around on the ground, nothing unusual.
However NEVER. EVER. point your camera upwards.

I very nearly screamed. This is the exact reason I hate these bastards.
