These spells were going to be invented by an ocean, wave and storm magus in a recent game hat I’ve had to exit.
Personal Ward Against Iron
Rego Terram 20, R: Personal, D: Diameter, T: Individual
The caster is warded against iron, which is deflected away automatically when it approaches their personal space.
(Base 5 to ward against dirt, +1 Diameter, +2 iron)
Swim Safely Among the Ice Flows
Muto Aquam / Ignem 5, R: Touch, D: Concentration, T: Special
The water immediately around the caster is warmed so it will no longer chill people or objects.
(Base 2, +1 Touch, +1 Concentration, +1 Unusual target surrounding the caster)
A few spells for a Magus with a strong focus in Aquam, a major virtue of Elemental Magic, and also a magical Vulnerability to Iron. On first look a boiling oil spell seems to need an additional requisite, however not for the elemental magus, who can ignore the effect of the Ignem requisite in the spell calculations. Harder for most magi to cast so they probably wouldn’t bother, but not for all magi.
I think these spells are justified as a CrAq spell could create water, optionally boiling water with an Ignem requisite at the same Base 4 as the base to boil water is also CrIg Base 4. Creating normal oil is equivalent to water as shown in the Creeping Oil spell in the Ars Magica book uses a Base 3.
I have also assumed that the example spells like Creeping Oil and the other Aquam spells show that boiling oil needs the Ignem requisite and a minimum level equivalent to CrIg4, instead of reducing the amount of oil produced downward by one more step in the base guidelines. That would make it similar to a strong acid and other highly corrosive Aquam or Terram based materials.
Jet of Bubbling Oil
Creo Aquam / Ignem 15, R: Voice, D: Momentary, T: Individual
Projects a large splash of boiling oil on a victim inflicting +12 damage.
(Base 4 “to create a liquid in an unnatural shape”, +2 Voice, +1 boiling liquid)
The Base amount created for oil is still a very large volume relative to the size of a human victim, so it is quite likely to cover a significant part of the victim which doubles the base damage of boiling oil from +6 to +12.
I initially started to consider allowing an athletics check to avoid some damage however the same should then apply to CrIg effects – and that just isn’t so. This is a conjured material so it can be automatically targeted as desired, and is resisted my MR or Parma Magica – again, just like Ignem spells.
A key risk for Aquam spells which isn’t really considered in the spell mechanics is the splash effects. A spray of oil will be potentially harmful to everything around it, and while that is not reflected in the rules in many places the same is true for many forms of direct damage.
Then moving on to more dangerous spells. Continue reading
