One of the best DND stories I've heard was about a party of adventurers who were tasked with saving a small village from a horde of undead. They had a paladin in the group who managed to turn many of the undead away, while the wizard cast powerful spells to hold the rest at bay. The rogue, being the sneaky one, found the necromancer controlling the undead and managed to steal the artifact that was powering the horde, thus saving the day.
