a dark elf noble  

This mob also casts the mez spell Confound (https://everquest.allakhazam.com/db/spell.html?spell=36083). I don't think it's possible to break the camp without the correct classes in your group. I tried with a WAR, CLR-bot, a healer merc, and a wizard merc. The WAR was the first to get mezzed, then the CLR-bot. After that, the mercs were slaughtered, and the warrior and cleric were next once Confound wore-off.
