Personally I would hire some adventurer types to do the job for meWell... Let's get serious. If you, as a real person, decided you wanted to go crawl around in a real dungeon fillled with ancient treasure, deadly traps, ungodly evil creatures eager to claim your soul and pesky vermin swarming to tear the flesh from your bones, how would you gear up for the trip?
If you're like most people I know, the first thing you'll do is grab your whip and pistol, and then you'll put on your fedora hat. "Fortune and glory, kid. Fortune and Glory."![]()

As much intel on the location as can be obtained.
