Did this today, I found the fight to be extremely easy as a warrior, never went below 80% HP after the initial round of skills.
I didn't have to kill any image, as soon as I got close to it, it would teleport back to the center and do the usual, it does the same over and over...
As for the thread, I got to 80 yesterday and just maxed weaponsmith an hour ago, when I decide for a weapon I'll get into crafting it.
