The best camp spot to spawn and fight this guy is the empty ledge right above where Magmaraug spawns. You just have to clear the 2-spawn on Mag's ledge and then you can CAREFULLY pull the trash below up here. Make sure you lead them TO the ledge. If they get pulled underneath they can aggro through the floor and bring friends.
The best way to get TO this camp spot is as follows. At least, best way from the hallway where people usually camp Galvanized Guardian. First, be levitated! Exit the back end of this hallway to the right. There is a thin ledge there. Jump across to the large rock dead ahead. You will need some form of LEV for the rest of this. Right after the rock is a long thin ledge which rises slowly and runs the whole length of this room. Go to its end. Now if you look off the edge you see several ledges. The one immediately under you has a blob on it. Off in the distance is an empty ledge. It's right after the one with the blob. You can jump off, assuming you're lev'd, and maneuver your flight to that ledge, without drawing aggro.
Even though it's a ledge and not very flat, you can make a campfire. Bring in your firepower and get to work huntin'!
