Gems

Description
Gems are the resource needed to obtain any of the circlets/weapons/tools from enhanced survival. They have a 1 percent drop chance from granite, and the variants depend on their specific biomes. When all of the gems are in the player's inventory, it will give them a shot at obtaining one piece of gear, or some exp (30-60), mostly scavenger. With the additional 2 gems in their inventory, the Blood and Ender gem, it is much more likely to get gear.
