Oro

Oro is the abbreviated name for Orozar Highstone, usually referring to farming his quest in Sorrow's Furnace.

When players speak about Oro Runs or Oro Farming, they mean taking Orozar Highstone with them into the Sorrow's Furnace so as to make sure the named bosses involved with his quest will be there when they enter. These bosses drop some of the more popular unique items in the game.
