This Uncommon crystal, pulsating with earthly energy, seems to have grown from the very heart of an ancient oak tree. It attracts powerful Glarungs, whose bodies rage with the ancient powers of the soil and roots. When moonlight falls on its faceted surface, the earth seems to respond - Glarungs emerge from the earth, answering the crystal's call. The brighter the glow of this artifact, the more earthly creatures respond, finding their power in the dark depths of the lunar cycle.
