  1. While I haven't played CoC 7 yet, one mechanic I'm really interested in the advantage/disadvantage equivalent in which a player rolls two or more "tens" d10s and picks the better/worse. It seems like a quicker way to handle difficulty levels than adding/subtracting modifiers or multiplying by some factor. I've used similar techniques in other games, e.g. rolling 3d6 and keeping the higher/lower two, or adding/subtracting dice from a dice pool, and those work reasonably well at the table. I'm just a little concerned that the CoC 7 version is a little too coarse-grained ... otherwise why would they also use multipliers (the infamous Normal / Hard / Extreme percentages). I also like the idea of opposed rolls replacing the resistance table, and consequently moving Base Characteristics to percentiles, but it does mean that small differences in the Active and Resisting scores can have large effects, while large differences approach 0% / 100% asymptotically.
  2. BRP is both flexible and forgiving. If a particular setting wants to posit a magical (alchemical?) technology, especially one involving immovable wards against intruders and certain forms of magic, it's not too hard to add a skill. Costs in time and materials could replace POW sacrifices. Penalties (maluses?) might grow slowly with area, so a rich merchant or petty nobleman might be able to protect his bedchamber and treasury with two separate enchantments, but only an emperor working with an arch-wizard could protect his entire castle. Or you could adapt "Glyphs" (formerly Runes) in Advanced Sorcery (formerly The Bronze Grimoire), wherein each effect is a distinct pseudo-spell.
  3. P.S. On the subject of limiting magic items: You may want to look at Numenera or the Cypher System Rulebook, although its systems probably won't translate easily to D100. It breaks its "magic items" into three categories: oddities (which do weird things but nothing useful), one-use "cyphers", and "artifacts". The latter two have "levels" which may influence the strength of their effects but mostly determine which devices override which. Artifacts also have "depletion rolls": after every use, the player rolls dice (d6, d10, d20, or d100) and if the dice show a 1 the artifact becomes useless. Depletion rolls are easier than tracking charges, and keeps players from becoming too dependent on their fancy technosorcery. For that matter, the prevalence of randomly assigned one-use magic items does give players powerful "desperation moves" that don't permanently unbalance the game.
  4. By "enchantment" you mean the creation of "magic items", correct? (Warning: vague advice and pontification ahead.) You might want to adapt the rules for "invention" or "research" in other RPGs, notably science fiction and/or "mad science", or rules for ritual magic. Usually they work as follows: 1. A player decides what they want to build. 2. The GM (somehow) determines how much time the PC must spend, what special tools or material they need, and the difficulty of the task. Something "routine" like holy water or a one-use scroll might simply require time and raw materials, while forging Anduril (the first time) might be insanely difficult even for an immortal Elvish weapon master. 3. Assuming there's some risk or uncertainty involved, the player makes one or more skill rolls, adjusted by the difficulty of the task, to actually create the magic item. Failure means wasted effort and possibly spoiled materials; a Fumble might cause an explosion. The tricky bit is deciding the time, materials, and difficulty for a particular item. I have no simple tables or charts to offer. If an item reproduces the effect for a specific spell, e.g. a "spell matrix" in RuneQuest, one can simply make those parameters a function of the spell's MP cost, "level", etc. Otherwise the GM will have to gauge the "power" of the item. The (ritual) magic system in Barbarians of Lemuria, for example, divides all magical effects into four categories: Cantrips (minor narrative effects), "First Circle" (whatever a trained human could do with the right equipment), "Second Circle" (beyond normal human ability), and "Third Circle" (world-shaking rituals most often used in swords-and-sorcery as the thing Our Anti-Hero is trying to prevent). Their alchemy rules have similar coarse-grained categories. See also its multi-genre derivative Everywhen and its suitably generic "Invention" rules. Also note that the prevalence and power of magic items will set the tenor of your game world. If items that grant +5% to +15% bonuses are easy PCs will stock up on as many of these things as they can. (It also stands to reason that NPCs with sufficient gold and/or connections will also load up on as many of these things as they can.) The end result, at least in my experience, is that magic becomes just another technology. If powerful magic items that anyone can use become too common, it might trigger an "arms race" between PCs questing for super-gear and NPCs (or at least a harried GM) seeking defenses against them. The local evil overlord, hearing of thieves that can teleport into his treasury or bedchamber, will find a way to stop them, particularly if he knows (or is) a sorcerer. My own preference is for low-magic worlds where uncommon "masterwork" gear -- mundane or magic, if there's a difference -- grants small bonuses and true "magic items", made with lore now mostly forgotten, are unique and dangerous to use. But it's your game.
  5. (Arise, stale thread! Arise!) Unfortunately I spent way too much on the Aces & Eights Kickstarter, mainly because of the Shot Clock. I'll probably regret it. Any comments about the Western system itself?
  6. Not having played it, I think it provided a "Platonic ideal" of RPGs, or at least something close to The Simplest Thing That Could Possibly Work. It tossed out all the wargaming mishegoss of hit points, armor points, movement rates, damage dice, modifiers for every little situation, and so on. Did you roll better than your opponent? Then you Did the Thing! If it's an extended contest, you each roll to Do the Thing until one person Did It more than the other and/or Did It the required number of times first. Granted, the "cancel masteries and roll low then calculate a success level" mechanic isn't as intuitive as "roll high, beat a number". And there's something to be said for fixed difficulties. And it's been done before: White Wolf got pretty close, S. John Ross's Risus is HeroQuest Lite with d6s and funny stick figures, Fudge and D6 were leaning that way. and I'm sure somebody else got there and didn't know it.
  7. A crazy idea I had two weeks ago, but which I thought it ate: Off the top of my head, what if we always rolled 2d6 - 2d6 for damage, adding a fixed positive damage modifier for a weapon (and +db) and a fixed negative damage modifier for armor? E.g. a Scimitar (1d8+1) would have a +5 damage modifier; with a decent Damage Bonus (+1d6, for example), that would be +8. Leather and Ring armor (1d6+1) would take away -4 of that damage. So the average damage would still be 4, but the standard deviation would always be +/-3.42. or roughly 3. That is, about two-thirds of the time you'd get the sum of the modifiers +/-3 ... but possibly anything from +10 to -10 (each 0.08%). Even against full plate armor, (1d10+2) there's a slight chance that a dagger does significant damage, but a very large chance it doesn't. Conversely, there's a small chance that a greatsword might just nick an unarmored opponent. (I noticed the dX vs dY effect as I was designing kobold-like creatures that had an average -1d4 damage modifier. If a short sword does 1d6, then the creature only does damage 58% of the time. I'm tempted to declare that they've created properly scaled knives and spears that eliminate the damage modifier but do two die steps less, e.g. 1d3-1 or 1d2 damage. But then that eliminates the stunning successes. It might be better to keep the 1d6 - 1d4 but declare that every attack always does at least 1 pt of damage. They'd do more than that only 42% of the time, with 25% chance of 3 or more points and 4% chance of 5 points.)
  8. Unless your Glorantha includes a Time Turner.
  9. Maybe also with a section on making monsters, because that's what I end up doing anyway (when I'm not making humans or stock monsters weird/creepy despite their familiarity).
  10. FWIW, Numenera has a limit to the number of one-use "cyphers" a character can carry. Beyond that, they react unpredictably and start losing power / melting down / going off. The number ranges from 2 to 5 (6?), but cyphers can literally do anything. In another hypothetical game maybe there's a separate, higher limit for health potions, minor amulets of luck, and the like. For that matter, you could look at D&D spells not as mystic potential but as little gizmos that "magic-users" carry around.
  11. While most of us like the variety of d100 magic systems, sometimes a setting or set of players would like one system that stretches from the minor buffs and curses of Battle Magic to the heights of Sorcery (or Divine Magic). Battle Magic at first blush seems like a good basis for such a system; just convert spells from Sorcery or elsewhere to a fixed or variable MP cost. However that cost may be huge, and a master magician will need pockets full of Magic Point Stores. Ways to mitigate that cost that I've thought of (i.e. stolen) include: Instead of using their own MP, master magicians can draw power from their surroundings, at a cost. See S. John Ross's Unlimited Mana for one such system, originally designed for GURPS. Master magicians have a special skill that reduces the MP cost of all spells by 1 MP per 10%, to a minimum of 1, much like Wizard levels in Tunnels & Trolls. Master magicians cast more powerful spells in downtime, then "freeze" them before they go off. At dire need, they "thaw" the spell and direct it at the necessary target. There's probably some limit to the number and strength of frozen spells, based on, oh I don't know, their "level" ... BTW, I started with Magic World but ran into the same conceptual difficulties as with Battle Magic. Their solution is to summon and bind demons, as in Stormbringer. Sorcery is the next candidate: simply port Battle Magic spells without Sorcery equivalents (e.g. Create Magic Point Store) to Sorcery, and build from there. Sorcery is a little more fiddly, though, so it's probably suited only for worlds where only a few people know magic, and sorcerers are specialists. I'll skip Divine Magic. A world of only priests sounds kind of dreary, but it might be some people's cup of tea. More exotic possibilities include stealing the Witchcraft/Island Magic/Dragon Magic/Mythos Magic base mechanic from Renaissance, porting Chaosium's Enlightened Magic, or creating yet another variation of Ars Magica/Mage improvised magic. I could also rip the systems from Classic Fantasy, either the original Chaosium release or the new Mythras version. All of those sound like a lot of work, both in ensuring they have a good spread of spells (or equivalent) and in documenting them for players. Is there some other OpenQuest-ready magic system I missed? Are one of the possibilities above not as clunky as they seem? Or should I start with the first principles of the setting -- in my case, an Arabian Nights / Crusades / Indiana Jones mashup with a few powerful sorcerers and a larger set of apprentices and "natural talents" -- and Frankenstein something together?
  12. Even if orcs outnumber human troops 10:1 or 100:1, there's still the problem that medieval weapons (bows, arbalests, catapults) are no match for modern weapons (autofire rifles, howitzers, drones). WWI demonstrated how well an infantry charge works against machine guns. Unless the invading army has Sufficiently Advanced Magic, or assaults key military targets simultaneously and unexpectedly using multiple portals, the best a fantasy army can do is establish a foothold on a small area (preferably one including a strategic military target) and drive outward in a long, slow, bloody slog. The longer the invasion takes, the more time Earth nations have to coordinate a response.
  13. I've always liked the GURPS approach where all weapons (not just firearms) can potentially do x1.5 (cutting, "large piercing") or x2 damage ("impaling") if they penetrate armor. Bullets, in particular, can get pretty nasty if they connect, but can just as easily glance off body armor. (There's also rules for armor-piercing rounds. And damage to non-living entities. There's rules for everything.) Shotguns, BTW, do "small piercing" damage, which means that any damage that gets through armor is cut by half, I guess because buckshot shreds armor but doesn't penetrate too far. On the other hand, looking at GURPS Lite (4e), most guns do Nd6 +/- 0..2, "piercing" damage (i.e. unmodified). A .357 Revolver, for example, does "3d[6]-1", for a range of 2..17. A ".30 Lever-Action Carbine" from TL 5 (e.g. a Winchester, I guess) does "5d[6]", or 5..30, average 17.5. A modern .338 Sniper Rifle does "9d[6]+1", or 10..55, average of 28.5 ... if it connects, it'll probably kill you, no matter how much you can bench press. My impression is that a lot of gun bunnies had input on GURPS (Texas, y'all), so the damages are probably not that unrealistic. So a "graze" or "flesh wound", as convenient as it is dramatically, is pretty damn unlikely, in GURPS at least. Short of going full Shot Clock (from Kenzer's Aces & Eights) the best approach, if you want to make guns scary but not auto-kill, might be a combination of range and aiming penalties and maybe a "damage cap" to represent "through and through" wounds that avoid hit locations with major organs. (Though there's still arterial bleeds ...) Or just embrace cinematic convention a la FATE or Cypher and assume guns do comparable damage to swords and arrows. Side note: a guy I knew once playtested a "realistic" FBI RPG. Oh, it was realistic: if you didn't follow standard police procedures, i.e. maximum paranoia, a bullet would take you out for the rest of the scenario.
  14. On a related(?) note, a long time ago I had an idea for an Evil Low-Tech Alien Empire of psionic world jumpers. The first infiltrators would jump, nearly "naked", into a new reality / alternate world / timeline / whatever. They'd cobble together a human disguise out of indigenous materials -- at which they're extraordinarily good -- and use their mind control abilities to infiltrate the host society. When they had enough people dancing on their strings, they'd call for more infiltrators, enslave the populace, extract any and all useful resources, and abandon the world for a new prospect, maybe calling in the truly terrible eldritch horrors to chow down as they left. My initial inspiration was D&D's Mind Flayers and the Mi-Go (particularly their ability to wear human disguises). I'm only halfway through The Nightmare Stacks, but it appears Stross had a similar idea: one agent makes the monkeys dance, then the rest come in for the kill. (Except the "elves" of TNS are desperate and on the verge of extinction, while the Alien Empire have been doing this for centuries if not millennia, and will do it for millennia more ... or until there are no new worlds to conquer.) With all the time in the world(s), media reactions aren't a problem, since people acting weird and against their best interests is practically Standard Operating Procedure, as this past year has shown. The only potential problems in a modern society are 1) sudden revelations of the Alien Among Us, a la They Live, 2) possible failure of mind control due to different physical laws or an application of SCIENCE!, 3) some British physician in a police box, or 4) surprisingly competent armed resistance during later phases of the invasion. The aliens are good at hiding and pick up technology pretty fast, but they are kind of squishy, so unless they can protect themselves with their own army the proverbial angry man in a car (or Humvee) can mow them down with a satisfying splat.
  15. I kind of like the approach in the CoC 7 Quickstart: instead of point buy, everyone has (for example) the numbers 16, 15, 14, 13, 12, 11, 10 to allocate to his/her character's characteristics. That way everyone has a specialty, and everyone has some average/weak points. Since DEX and INT are more valuable, there's a temptation to put the 16 and 15 to one and the other, but maybe there's a further rule that if one of DEX and INT is higher than 13, the other has to be equal to or lower than 13. There are also weighted point-buy systems that make buying the highest values non-linearly expensive, but allocating 7 numbers is fast, simple, and prevents someone from "cornering the market" on a few stats or making characters that are blandly awesome.
