This miracle is affected by the Celtic wonder, which increases its power. It requires constant prayer power, so the player must have worshippers at the worship site to mantain it. In its basic form, black clouds and heavy rain are summoned within the selected area. The increased version adds lightning to it, and the extreme form adds a tornado in addition to lightning. It is considered an evil miracle, even if it's cast in its basic form and will affect the player's alignment.
