High Quality Content by WIKIPEDIA articles! This is a list of known stone casts used throughout the television series, Di-Gata Defenders. Sorcery in RaDos mostly uses special dice-like stones called Di-Gata Stones as a casting medium, and draw upon the land (or water if the caster uses Aqua Stones) and a portion of the person`s inner power. The innate powers found within the Wizards of Yan do not abide to using physical Di-Gata stones, as they can create them via summoning. However, they use their own power to do so.
