For the choker you need a galaxy gem as usual and a Mark Of Destruction and Stick Of Mastery. For the Mark of Destruction you need to kill a berzerk zelniak in Dawnshroud. This zone is EXTREMLY camped all the time ... there almost always a ton of ppl and a ton of trains in this zone so be wary at all times. The zelniak are slaughtered by many players throughout the zone for exp and fat so you can join in the sloughter or try to search around for the berzerk. I found him between the midle of the zone and the Sanctus Seru exit. He is a roaming Mob but it seems to me that larger zelniaks in general are in this area. A traker would be very usefull for this one. The Stick Of Mastery is found on a masterfull cheetah in the Scarlet Desert. I got him near the entrance to The Grey. In general smaller cheetah and other Mobs are near the ent to Twilight Sea and they get larger as you approach the grey. I stay on the edge of the zone and travel north and back to the ent to the grey and kill them till the spawn a named. I still get good exp for cheetahs in this zone at level 55 and the level range here on wandering Mobs can vary greatly so con everything. Do not med in the tunnel to the grey or the rocks near it as when a dummy agros the reavers and runs for the zone they will agro you if one can see invis; med further north and try to stay away from the grey ent unless you need to bug out =).
I will send in screen shots of the items soon.
