Here are a set of new and modified spells for an Ars Magica Verditius Magus with a minor magical focus in bronze. When I generated the Magus as a beginning Character it wasn’t possible to take all these spells, however they might represent future developments.
Bindings of Bronze from Robes of Silk
Muto Animal 15, R: Voice, D: Diameter, T: Individual
This spell turns an item of Animal based clothing or equipment worn by the target into bronze (typically a shirt, robe, etc), thereby hampering movement, affecting function, and increasing load. Exact effects will vary according to the articles worn by the target, ranging from no effect to practically complete immobilization.
(Base 4 to change a animal product to metal, +2 Voice, +1 Diameter, +0 Terram)
Bindings of Bronze from Clothes of Cotton
Muto Herbam 15, R: Voice, D: Diameter, T: Individual
This spell turns an item of Herbam based clothing or equipment worn by the target into bronze (typically a shirt, robe, etc), thereby hampering movement, affecting function, and increasing load. Exact effects will vary according to the articles worn by the target, ranging from no effect to practically complete immobilization
(Base 4 to change a herbam product to metal, +2 Voice, +1 Diameter, +0 Terram)
I’m pleased with these two effects as they are not incredible in power level and might have some utility apart from being a defensive / hampering spell. A starting character probably only needs to take one of them too.
Wall of Bronze
Creo Terram 30, R: Voice, D: Sun, T: Individual
This spell creates a set of thick bronze walls, with an equivalent mass to 10 cubic paces in a configuration chosen by the caster. Multiple castings may be required to construct large battlements. The Voice range also allows for walls to be created beyond the reach of the caster potentially crushing opponents.
Asteria of Verditius intent was a defensive spell which would aid battles, or also used for other ad-hoc purposes such as impromptu bridges or fords. Her sigil requires spells display markings of construction or measurement was expressed as regular measurement marks along each edge of the walls.
(Base 5, +2 Voice, +2 Sun, +1 size)
Tower of Bronze, with Fear of the Dawn
Creo Terram 35, R: Touch, D: Sun, T: Individual
This spell creates a heavily fortified tower made from pure bronze, with equivalent mass to 100 cubic paces of bronze. The multi-level building has thick walls, stairways between floors, a large lockable outer door, a ceiling hatch, battlements, four small internal rooms, a larger common, and storage pantries. While forming the platform will seek to anchor itself into the surrounding terrain either by wrapping around solid objects and digging into the ground.
Asteria of Verditius invented the spell as dwelling for her infrequent travel due to the extreme discomfort of staying in the wild, and her displeasure when trying to negotiate with mundane accomodation.
(Base 5, +1 Touch, +2 Sun, +2 size, +1 complexity)
Tower of Bronze
Creo Terram 25, R: Touch, D: Momentary, T: Individual, Ritual
This spell creates a raised and heavily fortified tower made from pure bronze, equivalent mass to 100 cubic paces of bronze. The multi-level building has thick walls, stairways between floors, a large lockable outer door, a ceiling hatch, battlements, four small internal rooms, a larger common, and storage pantries. While forming the platform will seek to anchor itself into the surrounding terrain. The size and internal configuration can be altered by the caster before initiating the ritual.
(Base 5, +1 Touch, +2 size, +1 complexity, Ritual)
An effect which allows the Verditius magus to test metals she may use, or those she might have created magically.
Measurement of Metal
Intellego Terram 10, R: Touch. D: Momentary, T: Individual
This spell informs the caster of the purity and quality of an amount of metal.
(Base 5, +1 Touch)
A reworking of The Crystal Dart (Ars Magica core book) using bronze, and also increasing the damage output. It is not worth increasing the spell level further for more damage as the effect is still resisted, so the caster needs a reasonable penetration score.
The Bronze Dart
Muto Terram / Rego 20, R: Voice, D: Momentary, T: Individual
A 10 inch bronze dart rises from the earth and strikes an opponent within Voice range, inflicting +15 damage.
(Base 3, +1 increase damage, +1 Metal, +2 Voice, +1 Rego)
A version of The Phantom Blacksmith (from Covenants p 51) for working with bronze.
The Spell of Worked Bronze
Rego Terram 25, R: Touch, D: Momentary, T: Group
The magus may transform a piece of bronze into a finished form, as if a Bronzeworker had shaped and formed it. Up to ten cubic feet may be transformed.
The magus must pass a Perception + Finesse roll substituting for Craft: Bronzeworker against an Ease Factor at least 3 higher than the mundane Ease Factor. Failure reduces the bronze to a slumped lump as if an incompetent beginner had worked on it.
(Base 2, +1 Touch, +2 metal, +2 Group, +1 flexibility, +1 size)
This spell is intended for use when a mundane supply of quality bronze cannot be found.
Forge of Purest Bronze
Rego Terram 20, R: Touch, D: Momentary, T: Group
This spell smelts and purifies up to ten cubic feet of bronze source materials. The pieces may be existing bronze work or raw copper, zinc, or lead bars. To achieve a suitable final result the caster must succeed a Finesse difficulty check of 12+. Appropriate craft skills may be add to this roll.
(Base 2, +1 Touch, +2 Group, +2 metal, +1 size)
Then to move the massive gathering of pure bronze another spell is needed; at the maximum size the volume of metal is larger than a modern wrecking ball.
Ominous Levitation of the Weighty Anvil
Rego Terram 25, R: Voice, D: Concentration, T: Individual
This moves any metal up to ten cubic feet in volume as fast as a bird flies, which can be used to move and then drop the object on targets. A volume of ten cubic feet will cause significant damage (approx +25 damage), and requires a successful Finesse targeting roll.
(Base 3, +2 Voice, +1 Concentration, +2 metal, +1 size)
A basic ritual to create a huge mass of bronze, so that the magus has all she ever needs.
Conjure the Enormous Cube of Bronze
Creo Terram 25, R: Touch, D: Momentary, T: Individual
This spell creates a 1000 cubic feet of bronze, in roughly cubic proportions.
(Base 5, +1 Touch, +3 size, Ritual)
A reworking of Rock of Viscid Clay (Ars Magica p.154) for use with metals. I chose to forgo the benefits of the specialization in bronze for the benefit of working with any metal.
Metal of Viscid Clay
Muto Terram 20, R: Touch, D: Sun, T: Part
Softens metal to become like clay, which may be sculpted or molded, and becomes slightly sticky. The spell affects a one foot cube of material.
(Base 3, +1 Touch, +2 Sun, +1 Part, +1 metal)
Lastly a spell to assist in transporting large volumes of bronze items.
Minuscule Thing of Bronze
Muto Terram 20, R: Touch, D: Sun, T: Individual
Reduces an item made primarily or wholly made of bronze by three quarters in each dimension, with an sixty-four-fold decrease in weight. Requisites are required for non bronze components.
(Base 4, +1 Touch, +2 Sun, +1 further reduction)
These effects, like all the others I’ve pondered are part of a new spells compendium for Ars Magica.
