Well, somebody asked how to kill a wizard without being one, and that is, far and away, the best method. It doesn't require a hall of pillars (which can be found, judging by a lot of pre-printed adventures, in nearly any dungeon in existence, and a lot of other buildings too), it just needs somewhere where it's too dangerous to cast fireballs and the like, but also has lots of places a rogue can run to and from (preferably with Spring Attack) without being in LOS. Sure, there are some offensive spells that require LOS, but the fact is, he's teleport locked (which means he ain't goin' *anywhere*), he's AMFed (which means he's got no spellcasting), and nobody can call "**** move" because it's not a dead magic area, and the guy was specifically looking to kill him, so would have planned accordingly.

How you get them there is a problem, true. But once they're in the right spot, something not unlike that Hall of Pillars scenario, they're dead meat. One teleport lock scroll, one AMF scroll, kibble at leisure, all good.
