Ars Magica GRIMOIRE

@Toa

... tried to keep it low, but I guess that's the best I can do. Target: Part is required so you can still swim, and the requisites are required because air is not considered a gas and thus doesn't push the water away on its own.

On the other hand, evidence (bubbles) suggests that air naturally pushes water aside. So I would be in favour of dropping the Aquam requisite, saving you 1 magnitude.

Also, I think a Base 3 might be sufficient and change it from Re(Cr) to Cr(Re). You create fresh air around your head, and keep it there in a bubble. Creating fresh air is Base 1, while controlling it is Base 2. Thus a Base 3 would be reasonable. That would drop the overall level to 20, in line with Lungs of the Fish. Just different flavour of spell.

[The_Fixer]

IIRC, there's a spell just like that in the Hermanus chapter of LoH.

Serf's parma, you should check it in case I'm sprouting nonsense, but I believe it's a straight CrAu base 01 to create fresh air… But with added magnitudes since this is very unnatural. IIRC, the end result is also on par with IoL. Any attempt create air under water would suffer from the same problem, which is probably why Lungs of the Fish gets around this with Muto.

[MarioJPC]

There another near spell guideline on tSE-TT, for the Dolphin Automata that works like a Submarine.

[Lamech]

Behold the ultimate spell. As in the last one that will ever be cast.

Ultimate Spell: PeTe(re, ig) 120
Range: Touch, Duration: Mom, Target: Ind, Ritual
This spell explodes the planet with a burst of natural motion. The strength is sufficient to overcome the gravitational binding energy (or in the medieval paradigm disrupt the cause for natural motion downward). While only earth is directly effected the force will destroy most everything else and scatter it across the higher spheres.
Base 3+2 metal+1 requisite+1 Touch +23 size.

Doable with a major research project and a wizard's communion for casting purposes.

[Lamech]

In a similar vein to the above spell, this will require an even larger research effort, but if you pull it off the price is well worth it. It uses the lunar sphere as its boundary. The limit of the lunar sphere is not broken, nothing beyond it is affected.

Hell's Eternal Oblivion - PeVi-150
Range: Sight Duration: Mom, Target: Boundry, Ritual
All infernal creatures in within the lunar sphere lose 20 points of infernal might.
Base 10 +4 Boundary, +3 sight +21 size

This would be a massive project, top magi from the whole Order, lead by someone who has studied and practiced for years on organizing people into a lab. That same magi will want great PeVi too. Intelligence boosting rituals for all, a dedicated lab etc. A weaker version of the spell to claim a similar spell bonus. And casting it would need a full set of level 50 wizard's communions. However, after firing it three time? No more demons. Every single one of the monsters in existence would be destroyed. Well at least the ones that reside on Earth. (RoP Infernal puts the max might of a demon at 50. Losers.)

[ironboundtome]

Reviewed in thread, adding here for completeness.

The Unobtrusive Observer's Sight in Stone
Muto Terram / Mentum 30, R: Touch, D: Sun, T: Part

The surface touched is awakened to consciousness. The surface is able to see and hear it's surroundings, will remember details of events for the duration of the spell.

When cast a small human face is added to the surface touched, and effect's perception is based upon the position of that face.

(Base 4 to awaken the consciousness of a plant in the earth instead, Mentum requisite in base effect +0, highly unnatural effect for earth +1, to affect stone +1, R: Touch +1, D: Sun +2, T: Part +1)

and

The Unobtrusive Observer's Voice in Stone
Muto Terram / Corpus 25, R: Touch, D: Conc, T: Part
The surface touched gains the power of human speech as long as the earth is already awakened.

(Base 4 to grant the power of speech, highly unnatural for earth +1, Corpus requisite in base effect +0, to affect stone +1, R: Touch +1, D: Conc +1, T: Part +1)

[ironboundtome]

A beefed up version of the basic make me bigger spell. Discussion was had in forums about how many size ranks per +mag to allow.
My basis was around the mass increase from a typical target's additional mags. alter the mags and +size boost in the underlined to suit your HR.

Form of the Lumbering Jotunn
Muto Corpus 20, R: Personal, D: Sun, T: Ind

This effect enlarges the Magus up to a very large (size rank 10) version of themselves. At this size the Magus is around 60 feet tall, and weighs over 100 tons.
The character’s combat mechanics are greatly enhanced, adding +20 Strength, +10 to Soak, -10 to Quickness. The character also gains the reach and leverage associated with the truly massive stance.

Requisites are required when cast to transform clothes and equipment, and not all equipment will be included in the transformation. The effect is designed with a girdle as the focus, which is removed to end the effect prematurely.
(Base 3 to utterly change the size of a person although still human up to size +1, +2 for D: Sun, +3 for an additional 9 size ranks)

[ironboundtome]

A simple reworking of GotBF for Animal targets.
Arguable if it should affect all animal targets, only affect a broad class of animals (beast vs birds vs fish, vs insects), a narrow class (predator mammals), or just a type of animals (wolves). I went with a wide application. YSMV.

Gift of the Bear’s Fortitude to Beasts
Muto Animal 25, R: Touch, D: Diameter, T: Individual

This effect grants the target animal a +3 bonus to Soak.
(Base 15 to Make a body resistant to damage (+3 Soak) from the Corpus guideline, Range to Touch (+1), Duration to Diameter (+1))

[ironboundtome]

Reminds me of the 3e spell, "what armed soldiers"

Subsume the Irritating Hovel
Muto Terram 20 / Auram, R: Voice, D:Mom, T: Part

This spell alters the ground within the target area so that it is briefly transformed into air, and then quickly back again. Anything within the target area will fall as they lack the foundation of the earth.
The spell will affect mud, sand, dirt and stone, and anything upon these surfaces will be quickly buried and also potentially wreck a buildings stability.

If the spell is targeted beneath a specific spot, such as beneath a particular person a targeting roll is required. The effect is designed to create a cubic area, with a volume of 100 cubic paces of earth (5x5x4 paces), or 10 cubic paces of stone (roughly 2.2 paces per side). The difficulty of the targeting roll should be adjusted accordingly.
(Base 3 to change in to a liquid and add Au req, +1 to affect stone, +1 area increase, R: Voice +2, T: Part +1)

and for the more personal touch, a smaller effect area.

Subsume the Irritating Knave
Muto Terram 10 / Auram, R: Voice, D:Mom, T: Part

This spell alters the ground within the target area so that it is briefly transformed into air, and then quickly back again. Anything within the target area will fall as they lack the foundation of the earth.

(Base 3 to change in to a liquid and add Au req, R: Voice +2, T: Part +1)

and then needing to loot the bodies

Exhume the Bounty of the Earth
Muto Terram 30 / Rego, R: Touch, D: Conc, T: Part

This spell alters the ground within the target area so that it forces all materials it contains to its surface and ejects them. Everything unlike the surrounding earth is slowly pushed to the surface touched by the caster. While this spell does not directly affect any other non-terram materials, the unnatural quality of the enchanted surrounding material can still move other items. Heavier items may move more slowly, requiring the caster to concentrate for many rounds.

The spell effects stone and glass surfaces, as well as dirt, sand, and mud. This spell is excellent for exhuming lost items, coffins, and the like; although the gracefulness of the approach is questionable.

The spell affects up to 100 cubic paces of earth, or up to 10 single cubic paces of stone or glass; with a final shape and size determined by the caster.
(Base 4 to change earth so it is highly unnatural and adding Rego req, +1 to affect stone and glass, +1 to allow flexibility in shape and size, +1 to increase the area effected, R: Touch +1, D: Conc +1, T: Part +1)

[ironboundtome]

A glowing stones spell, a very poor man's version of a light effect.

Conjure the Orb of Sunshine
Muto Terram 20 / Ignem. R:Touch, D: Sun, T: Ind

The material touched glows brightly, and may be used like a torch. The creator Magus designed the spell so that a large volume of the enchanted material could be shared amongst many people, or used to light a large area.

(Base 3 for an unnatural glowing which affect up to 10 cubic paces of dirt, mud, sand, or up to 1 cubic pace of stone or glass. Glow very brightly +1, Affect stone/glass +1, R: Touch +1, D: Sun +2)

[ironboundtome]

Two ways to make the surface of a wall transparent one way. There was much discussion on these concepts a long while ago, but posting here anyway. Two effects to get to the same result, one Perdo, one Rego.

Ring of Impermanently Clear Vision
Perdo Imagonem 15, R: Touch, D: Ring, T: Circle

This effect removes the image from the area within the target circle, so that it is rendered invisible.
(Base 4 affect sight, R: Touch +1, D: Ring +2, T: Circle +0)

Ring of Transiently Clear Vision
Rego Imagonem 10, R: Touch, D: Ring, T: Circle

This effect removes the image from the area within the target circle, so that it is rendered invisible.
(Base 2 to make it appear 1 pace away, R: Touch +1, D: Ring +2, T: Part +1)

[ironboundtome]

A straight write up of the Creo Corpus guideline for resolving an aging crisis though magic.

Slip From the Reaper’s Grasp
Creo Corpus 40, R: Touch, D: Mom, T: Ind, Ritual

Resolves a terminal (or less) crisis caused by Aging (see Ars p.170). This effect causes Warping.
(Base 35 to resolve a Terminal aging crisis, R: Touch +1)

[ironboundtome]

Discussed here: muto idea - flatten an object to 2d

Flatten Miscellanea to Art
Muto Terram 20, R: Touch, D: Sun, T: Ind

The object touched is converted into a small two dimensional image of itself for the duration of the spell.
Casting requisites are required for the object when cast, and the effect can only affect non-living objects of standard size.

(Base 4 to change dirt so that it’s highly unnatural as “two dimensional”, Touch +1, Sun +2, secondary sub-effect to shrink +1)

[Ramidel]

Bad Neighbor's Gift
Creo Terram 40, R: Sight, D: Mom T: Ind +5 Size. The effect is slightly nonstandard.

This spell creates a massive trebuchet stone in midair, equal in mass to the missiles of the great siege engines used at Acre, and propels it into a target for +30 damage. In general, this is used to target a wall or a large unit (in game terms, a combat group). This spell is aimed, but except on a botch, cannot fail to hit the targets it is designed for; however, an individual may dodge with an Ease Factor of 6. Used against a castle wall during a siege, this spell is equal to a group of three artillery pieces, using Finesse in place of Siege Weapon.

NB: I decided on the three artillery pieces by a magnitude calculation, compared to the damage done by a mangonel.

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

[ne1av1cr]

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.

[ironboundtome]

A spell to alter another spell so that it is always considered optimised for the target.

Inhibit the Selfish Deviations of the Warp
Muto Vim Gen, R: Voice, D: Momentary, T: Individual

This spell alters the target spell so that it is considered tailored for the caster, as if the target spell was designed for the caster to not cause warping. This spell may alter any effect which is equal to the Muto Vim spell level less one magnitude (spell level -5). It is designed with Range Voice because it must be cast cooperatively with another wizard to limit the warping effects of their spells.

(Base of a Significant Change to less than or equal to spell level +1 mag, target own spells as +2 Voice)
