What to stock up on?

uhhh, diamonds are 20k/ore and 200k/ref in Khaini. They're starting to go to 30k/300k. Adamantium prices have gone up too.

Not so much on steel and mithril; those would be good ores to buy. It will take a lot of mesos to buy out the market though and create any sort of monopoly. Crystals are good to buy too, but those are much more pricey than their ore counterparts (with the exception of black crystal which is much more rare than Dark Crystal). You could also consider buying Sapphire and Garnet ores as these tend to be the more rare ores and it will be much easier to corner the market. Adamantium seems to be more rare as well.

Another ore that many people have not stocked up on would be Lidium. This ore is required to get the second level maker, and I'm sure many people would be willing to buy these ores rather than farm them themselves. If you've got the time, start hunting in Ariant.

I know of at least five diamond hoarders (including me) on Khaini. There are probably many more.

Just to make sure, would we need the refined Lidium or the ores for the second level maker? Also how many would we need?
