How about Mighty Banshees in the Pollnivneach's Smoke Dungeon? They drops tons of noted pure essence and other goodies. It quickly adds up. Aviancies are great too, but might be crowded. Ice Trolls with a cannon is a good money maker too.
Well, there was a little change. Icon in inventory looks differently now. But regardless, everyone's consensus is that there was some change, so demand is higher now - people want to check by themselves. I suspect it will cool off rather soon.
Borg is probably the most reliable source of blue charms. Also I keep getting about 10 blue charms per Aberrant Specters or Kalphite Soldiers slayer assignment (10 out of 140-160 kills). If you cannon them, you get blue charms relatively fast.
Thieving is very fast. At 99 I get up to 220K per hour and that's including time I spend on banking trinkets from the pyramid. After 91 it was steady 180-200K per hour.
Open a sarcophagus first and then the chest. This way you don't have to fight and simply ignore bug swarms and mummies. Otherwise, bug swarm will prevent you from opening a sarcophagus. And take a lock pick with you, to make it easier with sarcophagus.
Argh... It wasn't like that... I just wasn't sure I can post that particular link in here. Mods, please, delete if I really violate the rules... Here is a link to my Kingdom Management article I wrote a few months ago. It is published on a blog I write in: http://www.rshaven.com/how-to-manage-yo ... fectively/
I like it better than rune plate. If you earn it in Barbarian Assault minigame it will cost you 95K. If you buy from players expect 120-150K. Either way, I think it's worth it.
