Here are some inconsequential weather related spells for Ars Magica. Often small or innocuous spells will have additional subtle applications or ways to bend them circumstantially, however I enjoyed writing these are they are what they say they are. A weather wizard might have one or two of these in their grimoire.
Perhaps these were invented by a powerful and particular Auram specialist who disliked the whinging and procession of excuses the grogs used during rainstorms and showers at his home in the highlands. These spells gave temporary relief to the covenfolk, and would make simple useful enchanted items.
Strike Dry the Rainclouds
Perdo Auram 30, R: Sight, D: Momentary, T: Group
This spell stops rain from a set of clouds within sight. The clouds move and intermix in the sky as normal after the spell is cast.
(Base 5, +2 Group, +3 Sight)
It has the specific advantage of not warping the recipients when used to ensure covenant chores are unhindered.
