Wirt

Wirt is a Diablo I NPC, and is found to the far left of town, over a bridge and past the entrance to the Caves. It's a long, winding walk in Diablo I, made much more bearable by the fast walk in Hellfire.

Wirt sells items, but only one at a time, and he'll only show it to you after his infamous 50 gold fee. Wirt's graft engendered extreme hostility in most Diablo I players, and his fate as a gold-popping corpse in Diablo II was a form of fan service.
