[RPM] Improving Bullets with Magic
I'm trying to make sense out of RPM and I need some help.
Lesser Strengthen Energy says it can impart enough energy to a moving object to double its effect, so can this effect double the damage done by bullets (overpenetration not withstanding)? If so, how would an actual spell look like? Can I cast it on a gun so it speeds up every bullet it spews or would I have to make ammunition charms? Because it's enhancing the damage already done by the bullet, am I right to think I should use the Internal Damage table instead of External? How would I go about to improve the chance of hitting with said bullet? My guess is that Lesser Control Energy would allow to bestow bonus to hit, while Great Control Energy would allow turning it into a "homing" attack. Is it right? If so, how do I do the latter? Finally, what sort of spell would allow me to keep shooting the gun after running out of ammo? Greater Create Matter to make an ammo (or a full magazine)? |

Re: [RPM] Improving Bullets with Magic
I would target the gun rather than the bullet. I would treat it as a damage effect equal to the bonus damage (with the cost modified by accuracy, range, recoil, etc). If you just want a modest increase in damage though, you could just give a +5 damage for a narrow purpose (+16 energy).

Re: [RPM] Improving Bullets with Magic
Alexander is correct: the damage boost should go on the gun. some notes by PK, who wrote RPM and was assistant line editor at the time:

So the final effect is something like: Homing Bullet (30) Lesser Strengthen Energy (3) + Lesser Control Energy (5) + Sense Mind(2) + 10 lbs (0) + 3 hours (4) + bestow a bonus (+ 4 to damage) (8) bestow a bonus (+4 to hit)= 30 When shot, bullets from this gun ignore range penalties, roll against 14 to hit, and do an additional +2 damage per die.

Re: [RPM] Improving Bullets with Magic
Thanks for the help. Bestow a Bonus to increase damage was eye opening and being able to transform it into a per die bonus is great. Is the formula below correct for a more modest version of the spell as a charm? 11 is the safe threshold for a character with path skill level 15, so it would fit an out-of-box Sage.
Lesser Control Magic (5) + Lesser Strengthen Energy (3) + 10 lbs (0) + 10 minutes (1) + bestow a bonus (+2 or 1/die to damage) (2) = 11 It didn't come to me that I needed Sense Mind on homing-type spell. What would be the limit of a spell without it? Could control energy/matter alone be used to bestow a bonus to hit by, say, negating bullet drop due to gravity? Maybe increasing the character's ST for the purpose of avoiding penalties from insufficient minimum ST for a gun by negating recoil? |

Re: [RPM] Improving Bullets with Magic
Homing should probably be priced as an enhancement for the base cost of the ritual (increasing the final cost by 50% or more).

Re: [RPM] Improving Bullets with Magic
I'll add in addition to Bestows a Bonus being the way you add bonus or to hit rolls to damage, adding Enhancements simply treats the damage dealt as the "basic damage" of the attack and adds to that normally.
So if you did 3d large piecing damage with a pistol and you wanted to add Incendiary to the weapon's damage it would be a Lesser Transform Matter effect plus +2 energy. See p. 5 of How to Be a GURPS GM: Ritual Path Magic for more info on this.

Re: [RPM] Improving Bullets with Magic
Actually, it would be +4 (+1 energy per +5%), as 3d direct damage costs less than 20 energy (RPM, p. 17).

PU4p14 "Follow-Up, Universal" could be added to some Innate Attack you gain to make that damage add to any attack you make. You could probably add something like "Accessibility: requires guns" so it isn't added to all attacks in general. PU4p11 "Other Weapons" (Kaytee enhancing the RoF of her gun) is another approach to FUU, if you just wanted to do something like add Incendiary +10% or "Ammo Options" to your guns. Enhancements sometimes emulate Alternate Abilities here. Pg 19's "External (Indirect) Damage" could maybe be enhanced that way to add static effects that don't depend on the round's underlying damage. +1 energy per +5% means this will cost you +10 energy. I think you'd also need to put Delay +50% on there too, unless you were immediately firing your gun Pg 7 Path of Body (Yesod) also seems like an option here ("add any physical trait that doesn’t change the subject’s morphology") using Greater Strengthen Body to give someone Innate Attack. If you enchant the person it applies to attacks they make, but if you enchant an object (effectively a "can be wielded" character) then it applies to any attacks it makes, including attacks made by it's wielder. The incentive to enchant an item is that it would cost less energy per pg 16 Altered Traits since the innate attack can take "must be wielded" discount. This saves more points than "accessibility: requires equipment: gun" and also lets you lend the gun to others who weren't around to be enchanted, should you choose. Quote:
The force of a bullet comes from the actual round's explosion, so it sound right to enchant the bullet. Air guns OTOH might be a different story, they get the energy from CO2 cannisters. There are also spring guns (BB guns) which get the energy from the gun's spring and not the inert rounds. Quote:
Quote:
Pg 10 "“shove” an object in motion so it heads in (roughly) a new direction" sounds like at best you could change target to a new hex, but not a new target in that hex (or hit location) from 'lesser' alone'. If you just wanted to targe thexes with AEs leser would be fine, but if you want to snipe then I think "Greater" would be warranted to "exert perfect control over a moving object" Another less/great contrast in examples is "dictate the direction and rate at which a fire spreads" vs "make a fire stretch out and attack someone." Quote:
You might need some other paths to reflect the "scanning sense" of "homing", unlike "guided". Quote:
For bullets though you'd need: 1) bullet 2) cartridge 3) powder 4) primer So 1 casting of greater might be more convenient than 4 casting of lesser... Pg 7 mentions this dichotomy of effects but it's hard to find what that means... pg 15 mentions higher energy costs.. . ah it's 18/19 greater effects modifiers I guess. Quote:
Enchanting a gun for 10 minutes should somehow cost more than enchanting a bullet for 10 minutes IMO. Or do we view the benefit of "the first bullet this gun fires benefits" to be as valuable as "the first gun to fire this bullet benefits" ? Pg 18 table charges +1 energy for 10 minutes. You would need to do this for the 'wrapper' (lesser control magic) per 25, simply to have a "capacity to inflict +1 damage". That would be a separate +1 for 10 minutes, which would begin to take effect as soon as the wrapper triggered it. If all you do is fire 1 shot then that 10 minutes I guess is wasted. I can't find a way in RPM to emulate how "Link" works to extend durations as M131 allows (stretch out 168 hours of Continual Light to 168 days by only entering the room 1 hour per day). This distinguishes activate/deactivate and is probably like using Suspend Spell instead of Counterspell to halt a duration. There's a limit on how many conditional rituals you could have up (Thaum+Magery) which limits how many "magic guns" you could make before the old ones started expiring. To do greater amounts you'd have to have more powerful spells enchanting multiple guns simultaneously. The key question I have (which I can't figure out) is whether or not charms (being subset of condition rituals) contribute toward the T+M cap. Unless I'm overlooking "not subject to cap" on pg 27 features/ammunition it wouldn't seem like they're excepted... actually "Buying Charms" I can see now explicitly affirms it still applies to them: The maker may decide that the charm has been out long enough, and make enough new ones that the old charm deactivates!Anyone have an idea for a way around that? "I can end my charm by creating a new charm" sounds contrary to the spirit of "cannot cancel the spell before it expires" To impede stockpiling we could just make duration more expensive upfront, or require top-ups. |

Re: [RPM] Improving Bullets with Magic
Incendiary is a +10% modifier . . . so no, it wouldn't. It would be +2 energy.

Re: [RPM] Improving Bullets with Magic
Sorry, my bad, I thought it was +20%.
