Gems, their elements and over view

Gem fairies use certain gems to power their spells and each gem represents a different kind of element. Shapeshifting, Transfusion, metal bending and combo powers have no gem equal and you can not combine gems to produce powers like moon or stars.

Those who use Gems, can use a maximum of three, but power is reduced to 33% damage at max. During combat, it takes a full round (10 seconds) to switch between gems. Attacks and shields of the literal gems can be used, but they'd be considered non elemental damage. If the wielder of the gem wishes, they can destroy it to create a large scale fierce damage attack made of shards of the gem. However, this will cost said user with a drop in their spell damage for a time. Also any small chunk of the gem left over can be salvaged, but are utterly useless.
