Hey Gang in our Rot of Hiri Handia campaign Sorcerer King tried to save the nations crops during a severe drought. Over a very hot and dry summer he cast magic that brought rain to the fields. Then one day two weeks from harvest it did not stop raining. Crops rotted in the fields and everyone knew it would be a very tough year. Then the rats got in and started multiplying off the rotting grain. Then the disease set in and people began to die.
I imagine this being a result of a failed sorcery test. What would be then margic (facets sorcery?) what kind of ob would that vast scale magic be?
Weather Worker and Rainstorm are both Water/Air for Element, and Weatherworker is Impetus Influence (Rainstorm is Control). Weatherworker is Miles area, so probably could just outrightly do what you need. And could definitely happen on the Wheel Of Magic.
