Sabathius42 said:Complete Adventurer has a prestige class (whose name eludes me but I believe its called Dungeon Delver) that is basically a dungeon-only thief type. It has darkvision at an early level, easy to join requirements, and I believe even blindsight after enough levels. You could take that instead of normal rogue levels once you qualify.

That's the name. I was going to suggest the same thing. The only huge negative with the class is no sneak attack damage. But it's a pretty good rogue class substitute.
