Here are some spells I've been working on:
Charge of the Furious Wind (CrAu 25) - Charge of the Angry Winds using the next base up for hurricane-force wind rather than gale-force wind. I'm not sure what the ease factors should be raised to. Hurricane-force middle ground has wind speeds roughly 3x the middle ground of gale-force winds; even category 1's average is double gale-force's. Hurricane-force is strong enough to damage structures.
Talons of the Furious Wind (Mu(Re)Au Gen) - Talons of the Winds at Concentration. It does level-15 damage.
Trapping the Furious Wind (MuAu(Te) 15) - Turn a wind into a small stone like Trapping the Fire. (Base 4, +2 Voice, +1 Concentration)
Reins of the Furious Wind (ReAu 25) - Move a wind up to hurricane force around under your control, no faster than the speed the wind blows at. (Base 5, +3 Sight, +1 Concentration)
Sorcerer's Sudden Ceremonial Space (Mu(Re)Te 10) - The ground or floor centered around where the caster touches it reshapes to form a ceremonial casting circle "etched" into it. Casting requisites may be needed depending on the material, such as Herbam for a wooden floor. (Base 3, +1 Touch, +1 Concentration, +1 stone) I'm not sure the Rego requisite is actually needed, but it seems appropriate.
Object of Minuscule Proportions (MuTe 15) - Object of Increased Size but for shrinking, with an extra magnitude for more shrinking, and at Concentration. Objects become 1/10,000 the mass and volume, so each dimension decreases by a factor of about 21.5.
Breathe Life into the Art (MuTe(An) 20) - This spell transforms a sculpture of an animal into the animal it represents, assuming the animal is no bigger than Size +1 and the sculpture is no bigger than an Individual. Casting requisites may be needed if the sculpture is made of non-Terram/Animal material, such as wood. As with other non-permanent, created animals, the animal is not disturbed by the Gift. (Base 5, +1 Touch, +1 Concentration, +1 stone)
The Enchanter's Touch (InVi 20) - Sight of the Sigil (HoH:TL p.75) at T: Touch. This allows the caster to identify details of whatever spells they have under their control.
Unraveling the Threads of Vim (PeVi Gen) - Unraveling the Fabric of Vim at Touch. It dispels level+15+roll.
Master of Enchantments (ReVi 5) - The caster activates an effect from a magic item worn or carried with a known simple trigger. (Base 5)
Sustaining the Demanding Spell (ReVi Gen) - Maintaining the Demanding Spell at Moon. It sustains a spell up to level-10.
