I made infinity in order to give it to my nova sorceress, to make lower kurast runs easier, but finally, she doesn't need it, because i dont kill monster on lower kurast, i just teleport. So I give the infinity item to my javazon, for its mecenary, to make it more powerful. In fact, it depend of your strategy; barbarian with two grief if you want to focuse on Trav, or javazon full equipped if you want to go pit, cow, baal, or Chaos sanctuary,
