Can this propel the stone without Rego? Dropping it from above seems fine, but very unsure about moving it.
Yes, as a cosmetic effect. But aimed is pointless as the stone is magical.
This is Crystal Dart in flavour, and that has a req of Rego. It also has a "won't miss the wall, might miss a human" description. imho it needs a Rego Req, and potentially a separate thread for this chatter
I was trying to imagine the spells that a magi uses each day to improve the mundane parts of his life.
Purging the Unclean Body
PeCo 15, Req: Creo
Range: Touch, Duration: momentary, Target: Part
When the spell is cast, a ring of flame rises from the base of the person to their crown, destroying any waste products in the body. Additionally, it preserves the body and improves the balance of all humors. Anyone subjected to the spell will feel as if they had a healthy urination and bowel movement, and will also feel generally healthier. If the spell is cast regularly (at least once per week), it will add +1 to the quality of living for the current season.
(Base 3, +1 Touch, +2 Part, +1 Creo Req.)
I like it.
A spell to alter another spell so that it is always considered optimised for the target.
Concept discussed here
Cool. I really like that idea.
I've made it before, basically the same idea; I call it "Magic Tailor".
[size=150]Rain of Gray Death[/size]
This spell changes the rain falling from a cloud to dropping living and utterly scared elephants instead. Each elephant does +30 damage to the unfortunate sod who happens to be underneath it as it crashes into the ground.
Muto Auram (Animal)
Level: 35
Range: Sight (+4)
Duration: Momentary (+0)
Target: Group (+2)
Special: This spell is the result of my merenita who wanted to spend a few (7) seasons to make a spell that transform patches of air to a cloud of small butterflies that flew around the targets to confuse them and limit their field of vision. Unfortunately I had a laboratory with Warping 5 and I experimented with it quite a lot, so it became more and more bizzarre for each of the 6 or 7 seasons that I continued with it. It was a lot of Modiefied effects with +range/duration/power and at least three vesrions of "the actual effect is changed completely", but I got 15 xp to Magic Theory through Discovery, and yes... as part of my sigil being exaggerated many times to the normal: The elephants fall in precise gemotrical shapes and patterns and all the blood and intestines lies very orderly and there is almost no splatter as the blood follows the patterns...
...7 seasons for creating a mass elephant holocaust... 
If it's only Momentary then the elephants will probably turn back into rain before they hit the ground?
Definitely a Fae spell.

Oh, I meant diameter. sorry
Two effects for making miscellaneous object unable to move, discussed here. Note that the strength ratios are from the Transforming Mythic Europe sourcebook, p 125.
For most purposes the first spell will be more than enough, as i thought the effect could be used to hold doors closed, block areas, create impromptu stairs, hold aloft torches, etc.
And then a longer duration version, with more resistance to movement.
Agreed. Not sure if it'd work, but I love the idea.
Not sure if something like this has been done already, but I like the idea.

Dressed by the Storm
Muto Corpus, level 55
R: Per, D: Conc, T: Ind
Req: Auram
Your body turns into lightning, while keeping a vaguely human form, for as long as you concentrate. While in this form, you're extremely hazardous. Anything that comes into contact with your body will be as if struck by lightning (+30 damage) and you're blindingly bright (Stamina stress roll of 9+ to avoid temporary blindness. Botching means permanent blindness). In fact, you're also blindingly fast, being able to relocate yourself instantly anywhere you can see in straight lines (Perception + Finesse stress roll of 9+ to "land" safely if trying to move further than about 50 paces. A botch means that you missed the intended destination, probably causing harm to yourself or your surroundings, and automatically failing to maintain the spell. A failed roll means disorientation - make a Concentration roll of 9+ to maintain the spell, with a botch meaning adverse effects like motion sickness). Any successful relocation will also produce a booming thunderclap (Same roll as for blindness, in this case to avoid deafness and/or being blown away by the shockwave).
While in this form, you aren't solid - actually, you aren't liquid, not even gaseous, however, lightning is too chaotic for delicate actions such as slithering through small openings (it would be like threading a needle in an earthquake). Of course, you can't really hold anything, being immaterial, immune to other sources of lightning, and there is the strange risk of conductivity. Coming into contact with enough metal or water will "discharge" your body, making it extremely difficult to keep your form (make a concentration roll of 15+ to maintain the spell. A botch means a very spectacular accident related to conductivity, like actually losing body mass, or finding parts of your body fused with metal objects or liquefied in a body of water). However, as long as you manage to maintain the spell while touching such things, you'll shock anything else in contact with them.
Finally, lightning is weightless (or so it seems), so you're not really bound by gravity, but the chaotic nature of this spell makes flight extremely dangerous... as extremely fast as it could be.
(Base 30, +1 Conc, +4 Auram effect wholly divorced from its normal context)
...
So basically it's a spell that turns you into a living Incantation of Lightning. I tried to make it as flashy and chaotic as it sounds, without being too annoying or meticulous with the effects. Basically you become immaterial, explosively noisy and shiny, zap the hell of anything stupid enough to directly touch you, and you can "quasi-teleport" around, but touching anything conductive will break havoc with the spell (or let you zap a whole beach full of people). You can also fly, if you're reckless enough to risk losing control of the spell while in the stratosphere, or if you really are in a hell of a hurry.
Basically, this spell has room for VERY spectacular effects... Both good and bad. I wanted it to be a very appealing eye candy full of traps, and let Darwin sort'em out, lol.
I used the Creo Auram guidelines for very unnatural weather effects since I felt that turning into human-shaped lightning should be way harder than turning into mist.
The level automatically makes this a ritual spell (see ArM5 p.114).
Oh crap. I'm too used to enchanting.
Well, I simply added lazily the guidelines for very unnatural weather events for Creo Auram to the Muto Corpus ones, but I could argue then that since MuCo spell guidelines already take the difficulty of turning into something made of air in account, lowering it to level 50 should be allowable.
Unless the spell effect seems too hardcore for formulaic.
Harry Potter Fan spell!

Hi guys, I don't know if you take request here, but I try 
I recently made a Flambeau Magus, with the impossibility to combine Creo + Ignem (at first i thunk it would be fun...), so he is mostly Rego Ignem but i have hard time to find an aggressive spell with this combination.
Have you a spell like this in mind or create ? Something that can replace ball of abyssal flames or pilum of fire. His second form is Corpus, so a ReIgCo is also possible. Hope i don't ask too much, and sorry for my english.
I believe that it will take as long time for a raindropp transmuted to an elephant to fall down on your head as it takes for me to hurl a ball of abyssmal flame 200 meters if using formlaic flexible magic and enhancing the range 1 step.
Curse of the solar retribution
MuCo Lvl 15
R: Touch D: Sun T: Ind
The curse of solar retribution makes the targets skin vulnerable to sunlight for the duration of the effect. The target receives for each beginning hour exposed to direct sunlight, +5 damage, when only face and hands are exposed, +10 damage for the whole naked body. The target receives no damage, if being in the shadow or during night or by protecting the skin with salt water.
