Sol A Melatite for Darkforgegreaves

[Loke]

I've killed thousands of clockworks leveling numerous characters there (sol a is one of my favorite zones), and like others have said, it just sounds like you had bad luck. I don't think they drop any more commonly in one area than another, so I'd just chill at that safe room near the swinging axe. I've seen it drop there dozens of times and that area is definitely safer than going all the way up to lava elemental. If you've got a group and want a bit of adventure, going deep into gnome area is pretty fun if you're level appropriate though. Safe room near axe is definitely the easy way to go though.
