If anyone is still playing, I have the answer to the limited Malachite problem. If you've researched this at all, you should know about the loot in the hinterlands on the boat behind where you encounter the dragon. There's two loot piles on the boat. This trick works for both. When looting the piles, DO NOT TAKE ALL. Grab everything but one item (I usually leave the gold). So loot the Malachite from the one chest, leaving something still in it. Then, open up your map, and travel someplace else (globally). You need not stay long. Hop right back to the camp closest to the boat. Travel back to it. All contents will be refilled (including the Malachite). Wash rinse repeat if you like. So unlimited supply is at your fingertips. FWIW, this works with any chest in the game, just don't loot all the contents and a random selection of loot will reappear after traveling....
Cheers.
