pixie swatter rips through the ethereal warriors, and i assume its doing slayer damage to the dark wisps too, and since any char can use blackrock armageddon spell on the shadowlords i say using a meleer is best... however its nice to have the tamers there to tank some of the things, and probaby an archer with a good mystic wep is best for killing the berserkers, just shoot them over a hedge or fence or something
