Recently a poster on the forums asked:
“I was wondering how someone would model soul stealing spells and creating soul gems (that function basically the same way as Mana-stones). I don’t see any spells, besides maybe soul jar, that represent ripping the soul of of a being and converting its energy into a Mana-stone.
I was also wondering how damage to someone’s soul would be modeled. Maybe direct damage to their Will rather than HP or FP with 0 Will resulting in instant dead with no chance of resurrection?
And finally, could such a soul stone function like a dedicated mana-stone that only recharges based on soul damage that is dealt?”
Well that’s an interesting series of questions, isn’t it? As someone who has toyed around with the value of souls before I felt obligated to weigh in on this.
Soul Furnace (VH)
A Soul Furnace is a Powerstone that is powered by the soul trapped within it. Use all normal Powerstone rules (limits by value, etc.), except that a Soul Furnace does not recharge its power normally. Instead, each Furnace contains a trapped soul (usually via Soul Jar or some other necromantic spell) that provides power to its bearer. No Soul Furnace may supply FP higher than the trapped spirit’s Will+IQ; multiply this value by 1.5 if the soul possesses Magery 0, by 2 for Magery 1, by 2.5 for Magery 2, and so on. Those with FP (Magic only) or ER (Magic) add this value to Will and IQ before taking Magery into account. Soul Furnace’s recharge at a rate equal to the trapped soul’s Will/5 per hour. Mana Zones have no effect on this rate and multiple Soul Furnaces can recharge near one another without ill effect. As long as the bearer takes no more than total FP/10 in one use, the Soul Furnace can indefinitely supply power (but see below). If this limit is exceeded, make a roll against the trapped soul’s Will (plus Magery) at -1 per each 1/10th FP used (round up), Success reduces the Soul Furance’s FP by 1, failure reduces it by 2, and critical failure reduces it by the margin of failure. A critical success means no loss…this time.
Prerequisite: Magery 3, Enchant, and Soul Jar.
