Well this guy was easy for my lvl 58 Ranger but not until he gave me a few licks. It was how I went about approaching the corral that got me screwed up. First off, if you are a Ranger/Druid in wolf form, drop that crap because you will draw aggro on mobs that normally wouldn't (like invaders, fiends, and furious owlbears), instead opt to go with normal sow or get Spirit of Bih'li from a shaman. Next, go to the opening of the corral but stand back a good bit to where you are clear of any aggro radius of the mobs inside or the wanderers out. Strafe (hold down CTRL and push left and right) until you see a mob come into play and target it, this should be your mob. If it is, run around the backside of the corral, minding to stay clear of the walls, and get just within casting range of the mob. If it helps just keep clicking your spell icon until you begin casting as you move, to find out if you are close enough. When you're spell lands on the mob it will pass right thru the wall and will not bring any friends with it. I obviously didnt need any of the items, except that I wanted a FT item without having to roll for it, so I camped my alts at the SV entrance and re-logged em when I found something good.
Case in point...
This item dropped last night after the zone hadn't been touched all day, basically. Was first time running war and came out like a mad man....except no FT item 8( .
