Elemental Crystals
From RPGWW Wiki
There is only one elemental crystal for each basic element. Each crystal is an elemental that has given up its freedom of movement in favor of a deeper connection to the Elemental Lord who is its patron. Elemental crystals are significantly more powerful than most mortals, and they are always more powerful than their subordinate elementals.
