just have a high level barbarian and use cyclone when they all gang up on you and be sure
to stock up on healing tonics.

I agree with the person above, a Barbarian's cyclone would be smart, but I prefere a Wood
Elf Ranger. Just turn around and run backwards when you start. Take out your bow (it has
to kill then with one to two hits) and keep shooting until the near by ones are all dead.
Then hunt down and kill the rest of them until the Undead warrior emerges.

You could use the Barbarian or the Wood Elf, but with the dark elf, use the disease shield
to deliver poisond damage and keep runninf around.
