The fastest killer throw barb is with 2 Lacertors and a merc using Infinity. Use Highlords, LoH, Gore and Guillaume with a Fervor jewel. That’s enough CB for bosses and almost every hit will be double damage form either DS and CS, and then double damage form amp, while Infinity will remove most of the monster’s defense. I find it better to use Fort than Enigma and use a teleport staff on switch. I like to use an blood belt to increase OW odds, but there a half dozen great unique belts.
