Gems/Garnet

Garnet is a tall soldier Gem that comes in a handful of varieties. Weaker gems will flock to a Garnet for protection if left to wander. If the Garnet is damaged enough, she will avoid combat as much as possible by teleporting away until she gets healed. Garnets can also rarely have the ability to disarm her opponent completely.
