Vastly potent crystal forms, extremely rare
In their native form, Sancrists are faceted icosahedral gems twice the size of a man's head.Complete ones are very, very rare, however. More common (but still very rare) are splinters & shards. Sancrist Crystals have power to store, channel, focus & enhance magic and spells, and are greatly prized by workers of magic.
Only two complete Sancrist crystals are known to exist; one in the circle at Maraka and one in the hands of the lich Tersoal.
