The "Power" level(s) of Powerstone (and Manastone) in Low Mana
Recently a very interesting observation was made that I hadn't thought about:
Quote:
I'm not sure how that might work with "Very Low" mana suggested in Thaumatology (perhaps monthly?)What I hadn't considered is the secondary issue of needing a higher "power" (ie higher skill in Powerstone) to make powerstones that would recharge in low-mana. I guess that would be skill 25 to work in 'very low' mana due to the -10 penalty there. Since Powerstone is an enchantment spell, would it abide by the "Power of a Magic Item" on M17, so the "Power" would be the lesser of your effective (ignoring Mana penalties) skill in "Enchant" (a prereq for Powerstone) or your effective (ignoring Mana penalties) skill in "Powerstone"? "can spend extra energy to raise his effective skill, and hence the Power" seems like a way around this. 20% of 20 energy is 4 points, so every 4 energy would be +1 to a powerstone's power, and every 20 would be +5? Given the absolute minimum of 1 hour time when using "Quick and Dirty" enchantment, and the rate of 100 energy per hour, assuming you can amass 100 energy it's economic time-wise to use that much, so a 20-energy powerstone enchantment with 80 extra energy would be +20 to skill. That would absorb the -10 for even "very low" mana and allow you to use 10 assistants.
The sticking point is this: "If an item has several spells on it, each spell has its own Power."Given that power stones can be built up over time into larger-capacity powerstones, and each involves a separate Ceremonial Magic casting (which may result in different effective skill, depending on your skill at the time, how many helpers, etc) it stands to reason that each casting would basically have a different "Power". This causes no complications if all castings happen to be in the same range, but raises questions if they're enough to cause enchantment disabling at low or very-low mana levels."No Mana" is easy to work with since powerstones / manastones can't be used at all (which is all well and good since you wouldn't need the energy, not being able to cast magic) There seems to be 4 obvious options: Which option seems best? This may be a consideration for "Manastone" too, since even though those don't regenerate, maybe a Manastone would need "Power 20" to be able to draw upon it in Low Mana and "Power 25" to draw upon it in Very Low Mana?

Re: The "Power" level(s) of Powerstone (and Manastone) in Low Mana
Option 1 is too prone to abuse - it seems like the best way to make a powerstone would be to imbue the first 1 point while funneling as much energy as possible into increasing skill (to maximize Power), then later coming back and doing a lower-skill enchantment to boost the amount of FP it can hold. I dislike Option 2 because it makes it too easy to wreck a good powerstone. Option 3 would be my preference, but could get a little complicated, particularly for a stone that's been upgraded many times, particularly if each upgrade imbued different amounts of FP ("This powerstone has 3 FP at Power 15, 1 at Power 20, 8 at Power 25, and 2 at Power 30"). Option 4 may be best for both simplicity and balance (the powerstone from the prior example would just have 14 FP at Power 23 or so).

I would just keep track of the first enchant, that's the power of the stone, additional more powerful enchants won't change it, and lower level ones sinply fail, you're not powerful (or skilled) enough to improve this stone.

We've never tracked the power of powerstone, too much hassle.

Using your example, if you got Power 30 the first two times, even suffering -10 to skill from Very Low Mana, it would still operate at Power 20... but if the average was lowered to Power 23 then it would be reduced to skill 13 and you couldn't use it at all in low mana. Option 3, though, would be less all-or-nothing, it would just temporarily function like a smaller Powerstone when the lower levels drop below 15 from the mana penalties but the higher levels remain above it. There would be no incentive to cast "Remove Enchantment" in this case since you wouldn't have to worry about the average. I'm actually starting to wonder about the specifics of Powerstones when their Power dips too low. Like what happens. As far as I know, at -5 (Low Mana) a Powerstone with 15-19 Power (dropping to 10-14) basically functions as if it existed in No Mana? A powerstone does a few things: Are there any of these which would stop functioning if it was brought into a No Mana zone? Like should a Powerstone lose all its stored FP if it passes through No Mana? I'm also not sure if Low Mana's 1 point per week regeneration would work if the power was 15-19 (the -5 makes the enchantment cease to function) or if it requires a power 20+ to work then. |

Re: The "Power" level(s) of Powerstone (and Manastone) in Low Mana
Increasing skill through extra energy gives +1 per 100% above +100% (+4 to skill), meaning that +80 energy for Powerstone would give +7 to skill, not +20 (Magic, p. 12). Even if you could get 100 energy, it is not terribly effective, as +7 Power should cost 5x as much.
This relates to the problem with the basic economic assumptions of enchanting. Journeyman enchanters need twelve skills, two at 15+, and an uncommon advantage, so they should be Comfortable, not Average, earning $100×Enchantment. Master enchanters need twelve skills, two at 20+, and an uncommon advantage, so they should be Wealthy instead of Comfortable, earning $250×Enchantment. This should quadruple the cost of enchanted items ($12,500/month for a team of one master and five journeymen ÷ 22 days/month ÷ 6 energy/day ÷ .95 = ~$100/energy point). |

That's assuming there's demand for their services at these costs, of course. If demand for magic is not high (at least at high prices), it might be that the best living enchanters can get is Average, Comfortable for a circle master. If social mobility limits ones options it might also be that this is the best job even a highly intelligent commoner can readily get, so those with Magery would still end up doing it. The expected income of enchanters, and mages in general is very dependant on campaign assumptions, though for what passes for a GURPS default assumptions I agree that at TL4- Comfortable/Average is too low.

Re: The "Power" level(s) of Powerstone (and Manastone) in Low Mana
The previous team could make Power 20 items through Slow and Sure enchatment or Power 15 through Quick and Dirty. They can only spend 6 energy per day with Slow and Sure Enchantment, which is used to derive the economics of enchanting (since most magical items cost more than 250 energy) For Quick and Dirty, the economics change somewhat, but it is still more limited because mages need a third skill at 15+ to accelerate energy recovery and depend on Powerstones to make up the difference.
So, let us imagine the same team optimized for QD. They can do four enchantments per day, allowing for one hour of recovery between enchantments. They will each need 20 7-point Powerstones, allowing them to dump 100 energy per hour into an enchantment, which is $120,000 of Powerstones (with a 20% return on investment per year and 264 energy per year per Powerstone used for enchantment, this adds ~$1 per energy to QD). As for our mages, they earn ~$1.5 per energy to QD, increasing the cost to ~$2.5 per energy. The increase in costs of QD actually increases Powerstone costs by 25% and, when do the final recursive adjustments, the final cost of QD is ~$3 per energy (50% from enchanters and 50% from Powerstones). So, the cost of QD should be $3 per energy, which means that casting Powerstone should cost $60 per point ($240 for nongems). A Powerstone casting on a staff would cost $240 per point (plus $10), meaning that the break even point for cost would be around 10-point ($2300 for the Powerstone and $2410 for the Powerstaff). A 50-point Powerstone is much more expensive than a 50-point Powerstaff ($71,500 versus $12,010). You would want to cast Staff beforehand, as it is better to ruin that enchantment rather than the accumulated Powerstone enchantments. |

There's a fifth option - use the latest result. It's what I would use.

Then, as for the whole needing the spell (which would be a technique here) at 15, couldn't you achieve that by spending extra energy to raise it to 15? I could see them doing this, pulling out all the stops, to make their first Enchantment-Only Powerstone, which they could then rely on more and more to build a 2nd powerstone (I think you can't draw on a powerstone to cast powerstone on that same powerstone?) and then the pair of powestones could alternate to boost each other until you had a decent pair of enchantment-only powerstones to eventually alternate between to build powerstones intended for other colleges (or broad application). Quote:
Also if taking a "the last roll is what counts" approach then shouldn't failing cause the entire powerstone to shut down? Since crit success gives a random bonus to the Power, it might be interesting if somehow the margin you rolled below 15 (on a success) had some influence on power too. Like maybe +1 to 15 per MoS/5 ? |
