The Dark Chest... wonder what's inside
So we all know how hard it is to find gems right? Before recent game upgrades, the only ways to get a gem were to buy one (for quite a hunk of gold) or to get lucky–or play long–enough to land on the right field at the right time to pick one up. But now, we have treasure chests! A treasure chest has unique weapons and Gem Fragments in it. If you get five fragments you can synthesize them into a whole gem!
There are unique lines of weapons in each chest, which cannot be bought or sold in the Merchant Guild. You can only add one to your collection by getting and then opening a treasure chest through the Thieves Guild.
Five of these equals one Zoasite Gem
Two of the newer chests in the game are the Dark Chest, in Tower II, and the White Dragon Chest in Tower VIII. The Dark Chest, as its name hints, has an eeire collection of weapons like the Dark Mace and the Venom Axe. In the Dark Chest you have a chance to find a fragment of Zoisite. The White Dragon Chest in Tower VIII houses such weapons as the Flame Spear, Aqua Scythe and Frost Whip…and in it, you might also find a Diamond Fragment!
Each chest holds one of six items. So if you are after a fragment, you have a one in six chance, but with so many amazing and exclusive weapons also available, you’re certain to get something you like!
