Stealing inspiration from the Rego Corpus guidelines Ranulf spends a season inventing this spell, to allow him to move his fires quickly
Flames that Leap Leagues
ReIg 40
R: Touch, D: Mom., T: Part
A fire or portion of a fire targeted by this spell is transported to a location up to seven leagues distant that the caster can either see or has an arcane connection to. Fuel that is being burnt by the fire can be transported with the fire by use of an appropriate casting requisite (typically herbam). if there is no fuel for the fire to burn at its destination or if the fire's destination is not amenable to a fire (such as a snow drift or a lake) the fire will be extinguished almost immediately. Ranulf uses this spell to split a fire into multiple fires at distant locations that are arcane connections to one another. Ranulf typically casts the spell with an herbam requisite to include some fuel for the fire at its new location but when it is important thatthe fire not be extinguished he also been known to both spontaneously cast a MuIg spell to allow the fire to burn without fuel and cast Enduring Flame on the original fire. Ranulf is hindered in his use of this spell by his poor eyesight and would very much like to acquire an item that would cast eyes of the eagle on him but he has not yet done this. Ranulf can use this spell in conjunction with not only unified flame and discourse of glowing tongues but also with transformation of fire or Transformation of Fiery Steel to send objects far away. Ranulf can also use this spell on Artisano when he is under the affects of Assumption of the fiery mantle.
(Base 30, +1 Touch, +1 Part)
He spends two seasons on the next spell because not being able to target metal with transformation of fire is a big drawback.
Transformation of Fiery Steel
Mu Te (He,Ig) Level 45
R: Voice, D: Diam, T: Part
This spell transmutes an object of stone, wood, soil, metal, or plant derived cloth or part of some such object into a fire. The fire is still essentially the original object and will not be extinguished for lack of fuel but it can be doused or extinguished in other ways. The transmuted fire is no larger than 2 paces in size and it is hot enough to do +5 damage. Objects smaller than 2 paces in size will turn into fires of their own size when they are subjected to this spell.
(Base 5, + 2 Voice, +1 Diameter, +1 Part, +2 to affect stone metal and gems, +1 herbam requisite)
Ranulf then cooperates with a fellow Milites magus and together they create two of the following item. Certainly the quick advancement rules make no allowance for cooperating with other magi and the flavor text says that it is rare for social reasons. Yet Ranulf can't make this item on his own and I'd wager that school of Flambeau magi with level 20 vim are rare as hen's teeth. Furthermore this isn't the sort of device that either Ranulf or the magus who cooperates with him would want any others to know about, it's incredibly useful to school of Flambeau magi and the trust garnered by decades of fellowship in the societies Milites has got to be worth something.
Ranulf spends five seasons: two seasons opening the rings for enchantment, two seasons instilling unraveling the fabric of ignem in the first ring, and one instilling Unraveling the Fabric of Ignem in the second ring from laboratory notes. The cooperating magus spends four seasons: two instilling Anticipation of Incineration into each of the rings and two seasons acting as Ranulf's laboratory assistant during the enchantment of Unraveling the Fabric of Ignem into the first ring.
I've gone beyond the printed rules with a timing trick here. Tell me if you think that it's justified.
School of The Founder's Advocate
This invested device takes the form of a silver ring inlaid with a ring of polished hornbeam. It was opened with seven pawns of vis and the enchantment capacity of the item has been filled by the two effects Anticipation of Incineration and Unraveling the Fabric of Ignem.
This device was created by a Ranulf and a fellow school of the Founder flambeau socitates Milites. Because it was well known that both of magi favored ignem magic, they worried that anyone who had advance warning of them might very well protect themselves with rego ignem wards against fire spells.
As is usually the case with such devices, the wearer must suppress their parma magica as they place the ring on their finger in order to allow the Anticipation of Incineration to target them. The ring functions only while the wearer keeps it on his or her finger. Anticipation of incineration only functions once per day, so if the wearer takes the ring off, it will not work again until the next sunrise or sunset.
Anticipation of Incineration
InMe Level 30
R: Touch, D: Concentration, T: Ind
This effect reads the mind of the target (the wearer) and determines when they are starting to cast a creo ignem attack spell on a target. Anticipation of Incineration then triggers unraveling the fabric of ignem. Anticipation of incineration was specifically designed so as not to warp Ranulf as a powerful effect (the item can still cause warping to him as a long term effect if he were the sort of fellow who wore it most of the time, which he isn't).
(Base 15, +1 touch, +1 concentration modifications: +5 levels item maintains concentration)
Unraveling the Fabric of Ignem
PeVi Level 40
Pen 40, 3 uses per day
R: Voice, D: Momentary, T: Ind
This effect has a linked trigger. It is set off when the anticipation of incineration enchantment detects that the wearer is about to attack a target with a creo ignem spell.
This effect is intended to remove ignem wards such as Ward Against Heat and Flames (ArM5 p. 143) that might otherwise protect the target from the deleterious results of getting hit with multicast pillum of fire spells. The effect functions as Unraveling the Fabric of [Form] (ArM5 p. 161), dispelling all hermetic ignem effects of level 25 + stress die (no botch) and lower. It functions three times per day and it has a penetration of 40.
A caster who spends a few days practicing with the School of the Founder's Advocate can learn to cast their spells sufficiently slowly to allow unraveling the fabric of ignem to take effect before their attack spell. When the caster does this, their initiative is reduced by two for the rest of the combat.
(Base 5, +2 Voice, modifications +2 levels 3x per day, +3 levels linked trigger, +20 levels 40 penetration)
