First up travel to Wintergrasp and die. (yes thats right, die.)
and then when you are at the spirit guide click and then get transported to the west workshop graveyard.
Now go pull a monster that is close enough so it wont run away when you get to where you need to be.
Run back to the spirit guide and then jump to this ledge.
You will recieve the buff Spiritual Immunity which will make you immune to the attacks.
Now go and have fun getting weapon skills.
Hax in there xD
