A few Lava spells for Ars Magica

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 (see Hermetic Projects p.14).

Please note – Lava as written at Base 5 inflicting +15 damage is exceedingly powerful. This is better than CrIg Base 5 (+10 damage), and should be pondered seriously by players before being used. As noted in the comments below it is a little broken in terms of game balance, but I cannot (yet) find an explanation which contradicts the book references.

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.

  1. I haven’t followed that thread, but I read the spels nd the linked post. You’ve pegged the creation of lava as base 5, the same as the creation of base metal, like iron, Perhaps the thought is create stone with 2 additional magnitudes for the stone being melted. This makes logical sense. From a game balance perspective, my opinion is that you’re getting a of damage out of you levels and I’d make the spells either higher level or less damaging.

  2. I was hoping that the damage was kind of in line with other effects, as Lava gives slightly less damage than fire (CrIf base 5 +10 damage, vs CrTe base 5 +5 damage), so a level 20 spell inflicting +15 damage isn’t game breaking imho. The damage scales upward quickly if the target is partially or fully covered, which is something special for lava which I’ve not seen elsewhere. The spells with D: Momentary and splashes of damage it is actually impossible to have “coverage” damage, as the substance does not stay long enough.
    Perhaps surrounding a target in fire should have the same benefit, or lava is just a great substance?
    Or the immersion effect should be veto’ed by the troupe as being too powerful.
