Play the Act I quest "The Legacy Of Cain: Explore Cellar" segment. Take the waypoint to The Old Ruins and go north, then east. Go down the cellar to come across a named mob (Captain Daltyn) and his minions. Kill him for at least one magic item and some coins. Loot the cauldron for at least one health potion. speak to Leah for quest completion experience and gold. A loot chest also appears 40% of the time. Exit and repeat. The great thing about this method is that the pathway never changes. However, you will keep hearing a Tristram Militia whining about how he promised to save Marko and he did not.
