Kritika: The White Knights/Gems

Gems can be sold or 'enhanced'. This is not the same type of enhancement that applies to items. Gem's 'Enhance' refers to combining to gems of the same type (color and level, e.g. Ruby +2) to make one higher level gem. This is a simple process and only requires two like gems and some gold. With a gem level of +5 or higher, enhance success rates begin to drop. If an enhance attempt fails, the second gem used will be destroyed.
