He's not a static spawn, but he's just about as close as you can get and still have a wanderer.
He has the chance to pop in the northwest corner after a named giant has just been killed in the southwest corner. He does roam a bit, but I've never seen him outside of the top left quadrant of the zone.
He's weak, and a very easy kill, but hangs out with a lot of giant/burynai buddies who are a lot harder than him. He will get a heal or two from any passing cenobite that happens to look his way, and they'll usually assist him in the fight.
He was green to my 39 druid, 3 firestrikes and a combust took him out. He dropped hammer mentioned along with Excavator Claws. Its Magic, Lore, No Drop so may be for a quest, not sure which yet though. I tried to equip it, but no luck, say wgt 2.5 race/class ALL
