Affecting Volcanoes with Hermetic Magic

Volcanoes contain bubbling, liquid lava, volcanic rocks, sulfurous fumes, and clouds of ash, all of which makes it hard to determine which Hermetic Forms should be used to target a volcano. The following guidelines have been used in this chapter to decide which Hermetic Forms are appropriate, and can also be used as a guide to the development of your own spells:

Create a volcano, volcanic rock, lava, or volcanic ash: Creo Terram Create volcanic fumes: Creo Auram. Control/Cause/Stop the eruption of a volcano: Rego Terram (Ignem) Control the flow of lava: Rego Aquam Change lava: Muto Aquam Move volcanic ash about in the air: Rego Auram

Talk to a volcano: Intellego Terram

For Terram effects, volcanic ash is the same magnitude of effect as sand (which is usually the base magnitude of the effect), and the base Individual is 10 cubic paces of ash. Volcanic rock, and an entire volcano, counts as the same magnitude of effect as stone (which is usually one more than the base magnitude of the effect), and the base Individual is a cubic pace. Lava counts as the same magnitude of effect as a metal (usually two magnitudes greater than base), and the base Individual size is a cubic foot. See ArM5 (page 152) for details of how the magnitude of Terram effects depends on the type of material being affected.

For Aquam effects, liquid lava counts as a corrosive liquid and the base Individual is a puddle with a volume of about 0.2 cubic feet (which is a pool a foot across, and six inches deep). See ArM5 (page 121) for details of how the magnitude of Aquam effects depends on the material.

For Auram effects, volcanic fumes and ash both have a base Individual that covers an area with a diameter of about 100 paces.
