Due to a discussion on the Ars forums I drafted some lava based spells for Ars Magica. The spells are a little rough, as I’m unfamiliar with lava as part of the Terram Form. It is worth noting that creating lava is Creo Terram, however making it any hotter requires Ignem to assist as a requisite (see Hermetic Projects p.12 for more details on lava in Ars). Base 5 CrTe is 1 cubic foot of lava, which flows very slowly, and inflicts +15 damage.
Ball of Burning Lava
Creo Terram 15, R: Voice, D: Momentary, T: Individual
A ball of lava covers a small area within range. This inflicts +15 damage to items and people splashed by the lava. This spell creates 1 cubic foot ball of lava.
(Base 5, +2 Voice)
Spray of Fluid Lava
Creo Terram / Aquam 20, R: Voice, D: Momentary, T: Individual
A liquified spray of lava covers a small area within range. This inflicts +15 damage to items and people splashed by the lava. This spell creates 10 cubic feet of lava which burns then disapates. Aquam requisite allows the lava to flow more freely.
(Base 5, +2 Voice, +1 Size, Aquam free)
Shroud of Immolating Lava
Creo Terram 30, R: Voice, D: Diameter, T: Individual
This spell creates a blanket of lava 100 cubic feet in size, which remains for the spells duration, inflicting +15 damage each round.
(Base 5, +2 Voice, +1 Diameter, +2 Size)
Cast of Molten Lava
Creo Terram 35, R: Sight, D: Concentration, T: Individual
For as long as you concentrate a jet of lava springs from your outstretched hand, covering an area within range with 5 cubic feet of lava each round. This inflicts +15 damage to items and people splashed by the lava, +20 for those partially covered, and up to +60 damage for anyone fully enveloped by the stream. Over the duration this spell creates a maximum of 100 cubic feet of lava, enough to cover people or the side of a building. The lava disappears when the caster ceases concentrating.
(Base 5, +3 Sight, Voice, +1 Concentration, +2 size)
Erruption of Molten Lava
Creo Terram / Ignem 40, R: Voice, D: Momentary, T: Individual
A massive erruption of lava is created within the target area, inflicting +25 damage to items and people affected by the lava, +30 for those partially covered, and up to +70 damage for anyone fully enveloped by the stream. This spell creates a cube of lava up to 1000 cubic feet, enough to envelop a small building.
(Base 5, +2 Voice, +3 size, +2 inflicts +10 extra damage, Ignem Req)
This spell is part of the free new spells compendium for Ars Magica.
