If this is the one by the entrance to Lavastorm, he is pretty easy. Conned blue to me today at 18, and I tanked for pet the whole fight, didnt get below 90% health. (and I wear a full suit of cloth pretty much) Dropped bronze long sword.
The dark elf guards and corporals usually just drop a Bronze Long Sword, and sometimes Words of some sort. They give negative faction hits to InnerDreadGuards, OuterDreadGuards, IndigoBrotherhood, and one or two other, and a positive faction hit to EmeraldWarriors or some such.
