this helm can be hard to get, not because finding the pieces is hard, they are both in the field of bone on Kunark, but the troll (Gharg Oberbord) who drops the bulding plans is a bit of a pain. I am a lvl 21 shaman and had help from a lvl 30 warrior, we got our butts handed too us (mostly by all the skellies on the area)in about five seconds. We got lucky when we went into get our bodies because a lvl 54 SK was killing everything in site and let us loot the troll. I think a full group of lvl 25+ would have been ok but our little group of two was a joke. My advise, be prepared when you go to tackle Gharg Oberbord, Hes kind of a wimp but those skellies will agro fast and hit you with death touch that feels none to good.
As far as Bargynns digger it is pretty straight forward, get a good full group (if your below lvl 25) and be sure to have a caster who can root those pesky ferbies because they like to run off and heal themselves. EQatlas has some good maps of where he is found, me and my friend waited about 30-45 minutes for him to spawn. Just clear the room and wait for Bargynn (he was sort of a wimp too). By the way hes in Kurns tower thats located in the field of bone.
I have done this quest twice now, once for me once for a guild member, and not once have we even touched the troll. The easiest way to get Sythrak building plans is to have a monk go in and pull out a few servants onto the beach and FD. This is of course assuming that there are no servants playing in the surf at the end of the path, wich there frequently is for what ever reason. Once they are out they will either start walking back in one at a time or will end up in the surf. You can single them out by having a runner root one and start running up the hill, the rooted one will stay there in the surf, while the others chase the runner. The rest of your party then attacks the poor sap in the surf and when you runner is far enough away he gate back to the fight (as a note our runner was always a shaman or a druid). Takes a little longer than killing Barg I would guess, as the servants don't always have the plans, but you'll get them eventually. Of course you can ignore this and take on Barg and his 4 SK retainers the Guardians of Sythrak, not to mention they HT for 300 or so each. This is of course leaving out all the other servants who are gonna join in the fight and that little jester who is also gonna hop on in to kick yer but. As for a full group of 25 taking this room, send me an email and let me know when you plan this so I can watch, a good thrashing is always entertaining.
As I stated in the thread about the building plans, I looted mine off "a servant of Sythrax". For what it's worth, I went in with a level 35 Beastlord (helping a friend) and found that all the skellies are indifferent and the first 6 or so (not including the ones in the last room with the troll) were easy to single-pull and the plans dropped off the third servant.
Everything but the SK pets were dark blue to me at 35 too (they were green of course), so I got a little experience too.
sythrax building plans from troll sk in sythrax temple (underwater by spires on beach in feild of bone).
bargynn's digger from bargynn (named burynai in kunrs basement) spawns around a small water hole in the cave in the basement that has water on both sides (if that makes sense)
some gem (ask one of the peeps in old building near shaman guild, tell them "oxyn sent me"
"Oxyn sent me" to the female Iksar shaman in the house as you look out on the steps of the Shaman guild. Too bad the helm is the only nice scaledmystic post 40th. Model is Iksar bone helm. Crank - Dro
