The following material is Copyright (c) 1998 Geoffrey E. Fagan Yes, the section on cyberware is a little tedious; I'm trying to streamline it. Magic and Technology -------------------- Prior sections of this handout have elaborated upon the effect of increasing tech level with respect to the field of magic itself, but this chapter will examine the interaction of magic and technology at high tech levels. Some of the interactions are obvious, like the benefits of an Expert System computer program for Thaumatology or Alchemy, or a laser sight and head-up display for a Missile spell. Others will be described below. Psitech ------- Many psychotronic devices have application for magic as well. Technology which senses or affects astral presences, for example, does not discriminate between psionic and magical projection. A mage can manipulate teleswitches (p. P61) with the Mind-Sending or Telepathy spell, and he can impress a memory crystal (p. P63) or open a psychic lock (p. P65) as well; he could cast Reveal Owner [house rule - forensic spell list] instead of Signature Sniffer in preparation to pick such a lock. Kinetic bubbles (p. P68) affect weight for the purpose of Apportation and Manipulation, as Actuality Shields (p. P69) affect it for the purpose of Teleportion (and analogous spells which translocate through dimensions other than space). Each level of power of a Jump Beacon (p. P69) imposes a -1 penalty to magical teleportation spell skills. A magical teleporter trying to reach a jump beacon does so with a decreased skill penalty and fatigue cost of 1 per 5 levels of beacon power. A psionic shield (p. P73) imposes a penalty to any use of mental communication or Mind Control magic, the same penalty which it would impose upon Telepathy. A catalyst drug (p. P79) can raise latent Magery to Magery 1, and a _power_ proteus virus (p. P81) can impart Magery. A variation on the watchdog psiborg (p. P83) senses active spells and enchantments, using Electronics Operation (magic) skill. [The follow seems to require inclusion of the psitech from my campaign as well: [Detection Equipment [------------------- [Ghost Detector TL8 [This device, similar in appearance to a Geiger counter, detects flux on the astral plane such as that generated by a projected consciousness. When an astral character comes within detection range, roll a quick contest between his Astral Projection skill and the Electronics Operation skill of the ghostbuster (or controlling software). The greater the margin by which the operator wins, the more he learns of the astral presence of direction, bearing, and power. A basic hand-held unit weighs 10 pounds, costs $5,000, and has a range factor of «; i.e., it senses astral entities at a range of 1/2 times their Astral Projection power in yards. Larger models such as might be mounted on vehicles or in installation security systems cost more and have greater range. Complexity: Complex. Legality 6. [Astral Visor TL9 [This more sophisticated detector actually allows the operator to "see" into astral space, projecting a ghostly image onto a transparent visor. The resolution is equivalent to Astral Vision power (TL-6). A dedicated computer (Complexity 3 at TL9) controls the sensor with Electronics Operation (i.e., Astral Vision) skill 12, plus 1 per tech level above 9. $15,000, 10 pounds. Complexity: Complex. Legality 6. [Astral Visors are available as modifications for bionic eyes (5 points) for characters with Implant Computers of Complexity 3 or higher to run the controlling software. $30,000 (plus base hardware and surgery), weight negligible. [Psychotronic Weaponry [--------------------- [Spirit Sword TL9 [This baton projects psychic force into the astral plane, enabling the wielder to attack astral entities physically with Force Sword skill for 1d-1 damage (regardless of his physical strength), plus 1 per TL above 9. The wielder must have a means to detect the astral entity, like the Astral Visor above, which will depict the baton as the hilt of an astral sword. The baton can be used with Shortsword skill to affect physical entities as well, or its circuitry can be built into the hilt of an actual sword (in which case it can be used with skill appropriate to that sword, instead of Force Sword skill, even when attacking spirits). It can also be implanted (10 points). $30,000. Complexity: Amazing. Legality: 4. [Spirit Bullets: A large-calibre bullet (3d+) can carry a miniaturized version of the circuit found in a Spirit Sword, as can a gyroc (with physical damage of a chem round). Astral damage is 2 less than a Spirit Sword: 1d-2 at TL10 plus 1 per TL thereafter. Even if a bullet could be recovered, the capacitor-charged circuit burns out after one use. $1,000 per round. [Heavy Bullets TL9 [Similar to spirit bullets above, heavy bullets also have a one-use psychotronic circuit, in this case one that uses null-field technology. The bullet is "heavy" in the telekinetic sense, and it has an armor divisor of 2 against PK shield. Additionally, the charge from the circuit shorts into a bodyshield if one is present, disabling the device if it inflicts more than 10 points of damage. Heavy bullets double the normal cost of ammunition, and at TL9, they are incompatible with other special features which diminish the usable volume of the round (such as explosives or discarding sabots). [Ghost Chains TL11 [These grenades secrete adhesive to prevent bouncing from their target areas, about which they project a strength 15 inward-directed Astral Barrier (see below). In other words, any astral entity within the target hex must win a contest of Astral Projection power with strength 15 in order to leave, although the barrier is no more than one hex wide, so no further contests are necessary. The grenade can be set for a two-hex radius of entrapment with strength 15, and once it catches a ghost, the size of the field effect can be dialed down to pocket size, with ST 20. Once activated, the grenade maintains its barrier for an hour. Ghost Chains are available as Tangler ammunition. $10,000 per round. Legality 4. [Anti-Psi Technology [------------------- [Astral Repulsor TL9 [This field effect generator repels astral entities, who must roll a contest of Astral Projection power against the effective strength of the generator each turn or retreat one yard. That effective strength is equal to the actual strength, -1 per yard. For a typical model with strength 20, $20,000, 20 pounds. For a pocket model with ST 10, $10,000, 5 pounds. Complexity: Complex. Legality 5. [Astral Barrier:_ An advanced (TL10), modular version of the Astral Repulsor projects its full strength within a precisely defined border. Any astral entity which wishes to enter the barrier must win a contest against its strength and must win another contest each turn to remain within. If it loses, it must retreat toward the border a distance equal to the margin by which it lost. A barrier may surround an area and direct inward to act as a prison for spirits. To install a barrier in a large or oddly shaped area, roll against the lower of Architecture or Electronics skill. For a typical model with strength 20, one module per 20 square feet, $20,000 and 20 pounds per module.] Cyberware --------- When introduced at TL8, cyberware interferes with the spellcasting process, and Cyber-Rejection is worth just -10 points for mages even if it is worth -25 for everyone else. Cybernetic surgery entails loss of part of one's living mass, part of one's nervous system, part of one's identity and soul. [It's not necessary for game balane, I just like the idea that cyber interferes w/ magic; in my campaign, the mage's natural body is essentially his "antenna" for mana, so changings the configuration of his body causes interference.] A bionic hand imposes a penalty of -1 for spell-casting, a whole limb or other large-scale internal modification imposes a penalty of -3 (reduced proportionately for a partial system), and a Full Cyborg Body imposes a spell-casting penalty of -20! Implants and dermal mods impose a penalty of just .2 each (count each eye). Hardwired Reflexes are a special case: -6 for most systems, but just -3 for Interface Only, and -3 extra for Full Coordination and/or Enhanced Speed. [House rule: Hardwired Reflexes are basically a DX bonus and costs accordingly; Enhanced Speed is basically a level of Altered Time Rate w/ FT cost. Interface Only is for a neural interface - basically a Vehicle control setup.] An implant in a part which is already bionic, such as claws in a bionic hand, applies no further penalty, nor does an implant which does not interface or interfere with any biosystem (e.g., a cortex bomb or unremovable jewelry). The penalty for an arm is not cumulative with that for a hand, and the penalty for a full body is not cumulative with any other modification. A penalty of 0.4 or less may be rounded down to zero. Priests with Power Investiture normally suffer the same penalties, although some granting agencies have an affinity for cybertech, represented as additional levels of Investiture, each with the Cybermagery limitation, sufficient to entirely mitigate the spell-casting penalty. [House rule: Cybermagery is a level of magery that applies only to the tech college or to offset penalties for cyberware: -70%.] TL9 cyberware is low-impact, with half the penalties listed above, and TL10 cyberware is managenic, with no penalties whatsoever. Bioware which is custom-grown from the patient's own tissue imposes penalties as cyberware a tech level higher, but it may require a waiting period and it costs an extra ¬ point for every tenth of a point by which it mitigates the spell- casting penalty. Also, the supplier of custom bioware will be intimately familiar with the client's genetic make-up. Spell-Casting Cyberware Penalty Implant -0.2 Bionic Hand -1 Bionic Limb or System -3 Hardwired Reflexes -6 Full Cyborg Body -20 A TL8 Ghostcomp cannot cast spells at all, although later versions have no greater penalty than a Full Cyborg. Casting Spells on Cyborgs Record the spell-casting penalty for your cyberware even if you're not a mage, because it may affect your resistance to spells. Some spells affect biological targets (e.g., Necromancy spells), some affect inanimate targets (e.g., Making and Breaking spells), and some don't care. Mind Control spells, for example, do not distinguish between cyborgs and naturals. If a spell which affects biological targets is cast on a purely mechanical component (like Itch cast on a prosthetic limb), it simply fails. On the other bionic hand, a spell which affects inanimate objects, like Weaken, works fine on cyberware. The cyborg uses his Will to resist this kind of magic, with a penalty equal to the spell-casting penalty of his cyberware, to a minimum resistance of 10. If a spell which affects living things is cast on a partially cybernetic body part, the caster suffers a penalty equal to the spell- casting penalty of the target's cyberware. This holds true for healing spells. Regeneration will cause rejection of cyberware in the affected limb. Bioware and managenic cyberware is equivalent to the mage's body, but other cyberware counts as equipment. Touching a cybernetic limb thus does not fulfill the requirement of the mage's touch. On the other hand, a Body of Air spell, which only affects 6# of gear (clothing), will leave expensive cyberware lying in a heap on the ground. Alchemy: If a potion affects a meat portion of a cyborg (e.g., a love potion which affects the mind), it takes effect normally. If the potion affects a part of the anatomy which the the cyborg has had replaced with a prosthetic (e.g., a potion of speed for a cyborg with bionic legs), it has no effect. If the potion affects a portion of the anaotomy which the cyborg has had augmented mechanically (e.g., a potion of Dexterity for a cyborg with Hardwired Reflexes), it must overcome the relevant spell-casting penalty. Enchanted Cyberware If a cyborg has Hardwired Reflexes, Bionic Reconstruction, or a Full Cyborg Body, all of his cyberware may be considered a single piece for the purpose of enchantment. A cyborg must pay character points for enchanted cyberware, 1 per 200 points of energy in the enchantment. (Powerstones cost extra: 1 point per casting for the 1st 10 castings, 2 per casting for the next decade, 3 per casting for the 3rd decade, etc. Powerstores [see below] cost just 1 point per casting to any level.) A particularly useful enchantment is Magic Resisitance (p. M53), cast to increase the resistance of the cyberware, not the cyborg. Neurotech: Spells on Chips Theory Chips: At tech level 8, true spellchips are not possible. However, technical data for a spell may be stored. A theory chip contains the theoretical background for prerequisite spells so that a mage can master a complex spell without tedious study. Should a mage learn a spell with the help of a theory chip and then lose the chip, he casts that spell with a -1 penalty per missing prerequisite. Each spell on the chip has a character point value of « point and costs $1,000. Scroll Chips: Spells may be stored on chips with the Scroll spell, or stored on disk for use with an implant computer. Casting time for a normal scroll is twice the base casting time for the stored spell, but casting time with a scroll chip is not doubled. Enchanted Chips: Chips may be enchanted (as jewelry), with the normal discounts for spell engines, as above. The requirement that the chip be slotted (or implanted) replaces the requirement for Electronics Operation skill. Chip slots are rated for the point value of the chips they can slot; every character point's worth of skill or advantage equates to 100 energy points' worth of enchantment. Spell Chips: At TL9, a chip can actually enable a mage to cast a spell. Although a spell is a mental skill, it does require precise physical ritual elements, so Hardwired Reflexes are necessary to cast a chipped spell with a net level less than 18. If a mage slots a chip for a spell for which he does not know the prerequisites, he suffers a -1 penalty per missing prerequisite; theory chips can be combined with spell chips. Most chipped spells incorporate an Accessibility limitation requiring that they be cast from chips, providing a +1 bonus! Mana Manipulation ----------------- Magic technology at TL10 can concentrate mana, beam it like a laser to a receiving station, and broadcast it globally to increase local mana level. The mana level within such a beam (also called a ley line) is very high, and the level in the vicinity of the broadcast station is high, dropping off in concentric rings to the normal level for that area. A typical operation places a transmitter in a natural mana well, or generates excess mana with a farm of mana-producing yeast, and beams the mana to a client in a no-mana or low-mana zone, such as a mana-poor asteroid. The mana transmission may be aspected. A mining operation, for example, will benefit from Earth- aspected mana even if the local mana level is normal. [Regarding the yeast: My campaign has mana as a byproduct and necessary ingredient of life; some lifeforms are net producers and some - the ones you only find in those high mana fantasy worlds - are net consumers, at least during parts of their lifecycles. High tech genetic engineers can breed mana-producing yeast.] Magic Damper These TL8 devices interfere with magic in their area of coverage, imposing a -5 penalty to any spell cast within that area or upon a target in that area. It does not prevent the operation of enchanted items, but it does impose a -5 penalty to their chance of successful activation, if applicable. The penalty does affect fatigue cost and casting time. A mage can sense the area of a magic damper as he would enchanted items, perceiving it as an unpleasant sensation. Portable Magic Dampers are backpack-sized generators which affect a 5-hex radius, or a 2-hex radius with double penalty, -10. They draw power from a D cell which endures 48 hours. $10,000, 10#. Complexity: Average. Legality: 4. Pocket Magic Dampers appear at TL9, affect a 2-hex radius, and draw power from a C cell which endures for 24 hours. $6,000, 2#. Complexity: Average. Legality: 6. Augmentation Helmet This TL9 device increases the Magery level of the wearer by 1, provided that he has some level to start with, and it provides a second level with which the mage must pay an extra point of fatigue to cast or maintain a spell. (Effective levels of Magery beyond 3 simply provide a +1 bonus to cast spells.) An augmentation helmet runs for 3 months on a C cell. $50,000, 5#. Complexity: Amazing. Legality: 5. At TL10, this device is amulet-sized. $10,000, 1#. Spellguns This application of the mana transmission technology described above carries a spell on a beam of mana, giving it range comparable to other guns. The wielder fires the gun with Beam Weapons (spellgun) skill, using the statistics below. He suffers the normal ranged attack penalties to this roll, but if he hits, the spell takes effect with no range penalty. If the wielder is a mage, he may fire a spell with the spellgun by accepting a -1 penalty to cast it. In addition, anyone can load the gun with a clip of scrollchips (see above) and a powerstone. A dedicated computer selects the chip to be activated by voice or neural command. Spellguns malfunction only on a critical failure and inflict no damage of their own, hence they have no half damage range. Spellguns can fire a maximum of once per turn, but may fire less frequently if the casting time for their scrollchips is greater than a turn. Legality 3. Spell Pistol: SS 3, Acc 4, Max 300, Wt. 3, Shots 6/B, Cost $1,500. Spell Rifle: SS 9, Acc 10, Max 900, Wt. 9, Shots 10/C, Cost $2,000. Drugs ----- Channel This TL9 drug enables a mage to channel more of the energy cost of a spell from surrounding mana, reducing the cost to cast or maintain each spell by 1 FT per dose. As with Adders, roll against HT with a penalty equal to the number of doses taken; the effect lasts for an hour times the margin of success. On a failure, only one dose takes effect, for only an hour. During the period of effect, the power of the channel may cause the mage to feel Overconfident with respect to his magical ability. The drug so stresses the mage's magical connection that when its principle effect wears off, it leaves him unable to draw upon surrounding mana without pain. This pain imposes a -1 penalty to cast spells times the number of doses which the mage took, and it lasts as long as the primary effect lasted. Channel costs $40 per dose. Hypo form takes effect instantly; pills take 30 seconds. Complexity: Complex. Legality: 3. Sever This TL8 drug cuts the subject off from mana if he fails a roll against HT+Magery-4. In a very high mana zone, he can function as if in low mana, and in lesser mana he feels no mana. Furthermore, he cannot draw upon powerstones to cast spells. He can, however, continue to use scrolls and other magic items and to use powerstones in conjunction with them, for the items are not affected by the drug. Sever costs $20 per dose. Hypo form takes effect instantly; gas or pill form takes 10 seconds. Complexity: Complex. Legality: 3. Magic Booster An injection of tailored memory RNA can give a character knowledge of a spell, at the 1-point level. Roll against Will+4, minus the level of the spell (q.v.), +1 per prerequisite of the spell which the recipient knows. The knowledge lasts for an hour times the margin of success. Failure overwhelms the recipient with incomprehensible sensations, incapacitating him for an hour times the margin of failure. However, the knowledge (or incapacitation) will not appear until 12 hours after the injection. Cost for a dose is $100 times the level of the spell. Complexity: Complex. Legality: 3. Enchantment ----------- TL5+ alchemical science can produce materials optimized for enchantment, for a 20% markup in monetary cost. However, these materials reduce the energy cost of enchantment by 10%. The tech level of the material must equal or exceed that of the enchantment spell. Spell Engines Advancing technology makes options available which decrease the difficulty of spell-casting and enchantment. Gizmos which aid spell-casting but which do not cast spells themselves are simply fetishes which require technical capability to manufacture and possibly to operate as well. True spell engines are machines which cast spells like other magical items but which require less energy to enchant. The physical tech level of the machine must equal or exceed the magical tech level of the spell. For Gadgeteering purposes, the complexity of a spell engine which casts a Very Hard spell is Amazing, and one which casts a Hard spell is Complex (and so forth). Spell engines simply combine a variety of limitations (see Chapter 5) for enchantment, reducing the cost thereof. [That chapter is a slightly modified version S. John Ross's rules for customizing spells, available from his web page and from GURPSnet ftp.] Every spell engine incorporates controls which affect those parameters under a caster's control, such as range and area of effect. Operating the engine requires Electronics Operation (magic) skill, a Ritual Prerequisite worth a 10% discount to the cost of enchantment. (If the engine has all parameters preset, it requires no skill roll to activate, but it still receives the 10% discount.) Remote or computerized operation of a spell engine is possible at high tech levels, as it is for other machines. All spell engines additionally have one of these two 10% limitations, unless they are Always On: Either they do not - cannot - require fatigue or magical aptitude from the operator, or they require a special interface - another enchantment or Complex gadget in its own right. Either way, the spell engine is eligible for another 10% discount. In the former case, the builder must incorporate a powerstone and/or powering enchantment (Power or Draw Power). Most spell engines incorporate replaceable exclusive powerstones prepared with Repair Enchantment. [Yet another house rule: [Repair Enchantment Enchantment [If an enchanted item breaks, the enchantment fails. This spell can restore it for a fraction of the original cost, after the physical integrity of the object is restored. The caster must know the enchantment which he is repairing. [Cost to Enchant: Proportion of the original cost equal to the proportion of new material in the repaired object; minimum 10%. [Tech Level: 4. At TL5, this spell can replace a dedicated powerstone, and at TL6, it can replace an exclusive powerstone. (Thus, it could be used to prepare several interchangeable powestones in advance.) [Prerequisite: Enchant.] In the second case, the builder must supply a technological interface which costs $4,000: a throne or closet at TL6 or less, a helmet at TL7-9, a headband at TL10-11, or a jewel at TL12 or higher. At TL9 or higher, it may be an implant. As an enchantment, the interface costs 500 energy for headgear or jewelry and has Lend FT as a prerequisite. An enchantment which is Always On under normal circumstances still has a -10% limitation as a spell engine, because it is subject to downtime. The GM will set limits according to the physical technology which serves as its basis; electronic devices may run longer than cranky steam-tech, but repairs will be more difficult. As a rule of thumb, necessary downtime is 1/TL; e.g., at TL7, 1 day per week or 1 hour per shift. Whatever the limits, exceeding them risks damage to the device and therefore the enchantment. The final, archetypal requirement for spell engines is a source of physical power. Between power and maintenance, spell engines cost at least $5 per casting to operate, an Ingredient limitation worth another 10% discount, if not more. Engines which are Always On cost at least $5 per day. In addition to the -30% package described above, most early spell engines, the "infernal devices" of the steampunk genre, have a Physical Effect, clanking and belching steam, good for another 10% discount. Many are inconveniently large (-10%), perhaps so large that they require a vehicle for mobility (-20%) or disassembly for transport (-50%). These large engines usually have at least a level of the Blatant Magic limitation (-10%); otherwise, a removable component bears the aura of enchantment, although that single component accounts for half of the total cost of the device. Example: A hostage rescue team uses a grenade which casts Daze with an Area effect, a +40% enhancement. The spell engine has the usual -30% limitations, -30% more because the area is centered on itself, for a net cost of 800. As a Temporary Enchantment with one use, the grenade costs just 120 points of energy to enchant. An exclusive Manastone sufficient for a 5-yard radius costs another 25, so the grenade sells for about $300. [House rule: High tech level reduces enchanting time, but mages charge more by the hour, So costs are the same.] The radius of effect is fixed, so the user simply pulls the pin and throws. Powerstores and Manastores This TL8 technomagical device stores magical energy when enchanted with the Powerstone (or Manastone) spell. It does not cost less to enchant than a gemstone, but it can be enchanted reliably for greater storage than a stone. The only drawback of a powerstore is that it must have a constant source of physical power or lose its magic. An AA cell can power a 1-point store for 1 week. Divide this time by the power of the store, but multiply it by 10 for each upgrade in cell strength; e.g., a B cell can power a 1-point store for 100 weeks, or a 5-point store for 20 weeks. Powerstores are built with capacitors which can maintain the field long enough to replace a cell. Enchanting a powerstore requires a successful calibration roll against Electronics Operation (magic), as well as a roll against Powerstone spell skill. Failure of the Electronics Operation roll simply delays the enchantment, as the technician may try again every hour. Failure of the Powerstone casting roll indicates that the device has gained a quirk, as normal. However, the technician can attempt to get rid of the quirk by adjusting the circuitry of the powerstore, at the expense of the last successful application of the spell, rolling against Electronics (not Electronics Operation). Failure of that roll indicates loss of the last successful application *without* getting rid of the quirk, but the technician can try again and sacrifice another point. A critical failure indicates that the quirk cannot be jiggled out in this manner. Also, if the enchanter gets a critical failure on his use of the Powerstore spell, a last desperate effort with Electronics (a critical success) allows him to treat the failure as ordinary. The net effect is that the chance of producing a powerstore with no quirks is about equal to that of producing a powerstone with the expected number of quirks. However, labor cost is doubled because of the need for a technician. At TL7, protopowerstore technology is bulky, able to do nothing more than to enclose a manawell (q.v.) within a field that prevents its decay. It uses building power and costs $5,000 (per hex). At TL8, powerstore technology weighs 1 ounce and costs $500 times the amount of magical energy that the unit can hold. Halve cost and weight at TL9 and again at TL10. A compact powerstore, with half normal weight, costs 10 times as much, and a cheap store costs half as much but weighs 10 times as much as normal. Thus, you could build a 100-point TL8 powerstore for just $25,000 (before enchantment), but it would weigh 621/2#. Magical Miniaturization Most mechanical and electrical devices produce heat, and an excess of heat limits their efficiency or causes breakdown, so a cooling system accounts for a large portion of the mass and volume of the device. At TL6, enchantment with a variant of Cold can eliminate the need for a cooling system, cutting mass, volume, and price by approximately 25%. This enchantment costs 10 points per pound of the device's (reduced) weight. The use of Hideaway for miniaturization is obvious, but the ultimate in miniaturization is to place some of the components of an electronic device in the astral plane with a variant of TL7 Ethereal Body, at an energy cost of 200 points per pound made ethereal. The drawbacks of this technique are that the device is subject to anti-astral countermeasures and that the etheral component cannot transfer mechanical force to the physical component. The solution to that problem is to enchant an item as a gate leading to its other components; for example, you could enchant a pistol as a gate to a minigun. Cyberware: Compute the point cost of a magically miniaturized weapon implant according to its destructive potential, and add the point cost of the miniaturization enchantment as normal for enchanted cyberware (q.v.). [House rule links cost of implant weapons to damage instead of flat 5.] Increase the point cost of a computer or cyberdeck implant by 50% per level of complexity beyond that possible without magical miniaturization, and likewise add the cost of the enchantment. Most cybernetic systems will not benefit (in game terms) from miniaturization. Knack Symbiotes TL9 biotech can gengineer magical traits, and those traits in a benign, symbiotic microbe can bestow abilities equivalent to magical knacks (even if knacks are not otherwise known). This treatment costs $100 times the energy cost to enchant the same spell, and it costs 1 character point per 200 energy points to enchant. [House rule; knacks are too expensive in Magic.] The microbe reacts to neurochemistry in such a manner as to give the character control of the ability; otherwise, the advantage is eligible for limitation discounts accordingly.
