Ceremonial Magic Robes

Obviously, I'm behind on posting, but I may have some things in the near future. For now, here's an idea for riskier magic.

Casting a spell has a chance of attracting unwanted attention from beyond. Roll 1d6 any time a spell is cast: if the result is lower than the spell level, an angry spirit appears to attack the caster (optionally, the number rolled is the number of spirits that appear.) Thus, 1st levels spells are usually safe, 2nd level spells have a 1 in 6 chance of summoning and angry spirit, and higher level spells are riskier.

A set of ceremonial magic robes reduces this problem. These robes cost three times as much as Leather Armor and provide equivalent protection against spiritual attacks only. They provide no defense against physical attacks, and mundane armor provides no defense against spiritual attacks. Furthermore, no roll is required for spells of 3rd level or less.

Better quality robes may exist. Robes that act like spiritual chain mail cost three times as much as regular chain mail and eliminate the need for rolls when casting spells of 5th level or below. Robes that act like spiritual plate cost three times as much as ordinary plate armor and change the roll to 2d6, which makes high-level spells safer.

Helm Rule

When I wrote up the new rule for shields, I considered including helmets as well. But I had mixed feelings about that. I already use Shields Shall Be Splintered with helmets, and didn't want shields and helmets to be too much alike. There's also the matter that a shield can be moved to block blows aimed at any location, but realistically, helms should only affect blows aimed at the head, or generic, unaimed blows that could hit the head by accident. In a commment, porphyre77 suggested combining this with the "1 attack in 6 is aimed at the head" rule from AD&D, but I prefer avoiding the extra die roll for that.

In addition, my new priority is trying to eliminate as much "modifier math" as possible. That's part of the underlying motivation of writing the shield rule the way I did. The problem with allowing helmets to use the same rule as shields is: what do you do if you have both a shield and a helmet? I don't want to add the two effects and block all damage rolls of 2 or less. So what I think I would go with for helmets is the following:
Targets wearing helmets ignore any damage roll of 1, as for shields, unless the attacker is aiming for something other than the head. This does not stack with the shield bonus, but does work against backstabbing or other attacks that ignore shields.
Also, since I allow critical hits to cripple the head, I'd allow a helmet to reduce or prevent the added injury. You won't automatically get your head smashed in on a high damage roll to the head if you are wearing a helmet.

Shield Rule

I know I've been off-blog for quite some time, but I haven't forgotten. I've been distracted by some other things... but I've still been thinking about a lot of D&D-related matters, including the PDFs I've promised. Just need to work things out.

Here's one small rule I've been considering:
When using a shield, ignore any damage roll of 1. Damage is not otherwise reduced.
Note that this is in addition to the standard 1 point bonus to defense. It is also in addition to Shields Shall Be Splintered, if that is being used. Off-hand weapons do not get the same bonus. This rule should work with many of the retroclones, but in particular it's meant to compliment some changes I've been contemplating for the combat table.

Background: Although I don't completely buy the argument that shields are underpowered, this seems like a simple way to make them more important without lots of fiddly bonuses. I don't like DR systems you'd see in GURPS or The Fantasy Trip, and more and more, I prefer avoiding subtracting modifiers entirely. Ignoring low results is quick and simple.

I thought about changing it to "ignore any damage roll of 1 or 2", but that might be too much. Plus, it gives the option of using that variant for shield walls or very large shields.

Part of the reasoning behind it is that I treat the damage roll as rating for the attack instead of a measure of physical destruction. Rolling a 1 means you're still doing a potentially deadly attack, but not the best you could do. Rolling a 6 means you've done the best attack possible with ordinary one-hand melee weapons, killing even the luckiest ordinary human.

Natural Demons

A Tenkar's Tavern post encouraged a lot of people to talk about alignment again. But I want to talk about demons. Specifically, the kind of demons that aren't really demons.

Occasionally, people will mention how some old swords & sorcery stories do not have real gods, but have various monsters that are worshipped as gods. There's a giant snake with fangs that drip a paralytic poison that can also trigger astral projection. It lives in a horrible temple, tended by crazed priests who kidnap children to feed to it. The priests harvest the venom and use it for their own purposes. The priests believe the snake is a god, or maybe they just tell worshippers this so that no one tries to stop their nefarious activities. The snake, though, might not be intelligent or even aware of its followers.

What I haven't seen anyone discuss is the fact that you can handle demons the same way. They could just be really weird mutant animals, perhaps left over from genetic experimentation after an apocalypse (as are the demons in Thundarr.) Or perhaps each demon is created by conjuration magic, called forth from a sorcerer's id, as in Roger Zelazny's Wizardworld novels. Perhaps demons are former wizards who either transformed themselves to achieve immortality and power, as would a lich, or were transformed against their will by dabbling in dark magic. Perhaps they are space aliens, as is suggested in some Clark Ashton Smith stories, or in the Cthulhu Mythos.

The reason why I was prompted to write about monster demons by Erik Tenkar's post asking whether alignment is even necessary is because alignment really isn't necessary if you are using that kind of demon. If a demon is not really supernatural, or is only supernatural in the sense of having innate magical powers, then there is no need to  link them to a specific alignment, or even to each other. Each may be a unique entity with individual needs, goals and desires. In contrast, if you want demons to be part of a supernatural menace threatening the world as part of some cosmic battle, then I think you need alignment, though what form of alignment is really up to you. If demons can be banished from this world, if holy water has an effect on them, and if PCs can choose to join demons in exchange for power or oppose their plans, then you need to be able to tag characters to show which side they are on.

It's a matter of what kind of fantasy feel you are looking for. Epic, horrific, or picaresque?

Investment Table

I had a lot of positive response for Bribe, Craft, Train and the related posts on building resources like arcane libraries and holy shrines. However, at least one person asked for a table, since that would make the whole thing easier to understand. I thought it over, tried a couple different layouts, and settled on one that I thought would make the most sense: the Investment Cost Table.

The table assumes that the player tells you what they want to do and how much they spend. The player does not know the difficulty level, usually, nor the exact chance of success. You would look up the difficulty level in the header row, then read down that column to find the amount spent, or as close to it as possible without going over. The first number in that row is the target number to roll under with a d20.

The table leaves out some values: 6 to 9, 11 to 14, and 16 to 19. These are all 5, 10, or 15 + another number, so I figured this would be more compact and still easy to do.

Dungeon Puzzles

While I work out a table for the training and investment costs series and write up some additional posts on that topic,  I thought I'd take a break and talk about puzzles. This was most spurred by someone asking about non-riddle puzzles for a game aimed at kids. The age wasn't specified, but I'm thinking puzzles in general are better off as non-riddle puzzles, anyways, regardless of age. There's a slight difference in expected difficulty or subject matter from age to age, but I see these as the best puzzle types to use:

- One of These Things Is Not Like the Other
I'm sure most of you remember this from Sesame Street. Just include images or symbols of three or more things, most of which are the same kind of thing, but one of them is different. For example, you enter a room with four exits on the opposite wall. Above each door is a small animal statue: a snake, a turtle, a crocodile, a penguin. Only one door is safe; the other three lead to traps.

A variant of this: Find the Error. Naturally, you don't want to turn this into pixel bitching, but if you have three or four recurring motifs that are exactly the same almost every time you encounter them, any deviation from the motif becomes a clue. For example, let's say the dungeon is filled with statues of a man throwing a harpoon, a woman pouring water from a jug, and an eagle holding a fish in its talons, and the GM describes these the same way every time they are encountered, but in one room you see a man throwing a harpoon, a woman pouring a jug, and an eagle holding a rabbit, something's different.

- Analogies or Relationships

An analogy, in this case, means the well-known form "A is to B as C is to D", such as "a sword is to a warrior as a wand is to a wizard". A relationship means an implied analogy, such as the sword/warrior relationship implying an analogy of tool to profession.

This works well for the cliche "complete the statue" puzzle. You have a statue of a warrior in full armor with a hand gripped as if it could hold something. In the dungeon, you find several brass objects: a flower, a long-handled spoon, a spear. Which do you put in the warrior's hand? For a full analogy, you would have at least one complete statue indicating a relationship, such as a wolf eating a deer and a gryphon eating a horse. Then you have a pedestal next to these statues with an eagle in a position as if it is tearing into its prey. Your job is to find the object representing its prey and place it on the pedestal.

A trickier version is a room with three sealed doors and a bas-relief above each door, each depicting a different relationship, say a deer with a fawn, a wolf tearing into a cow, and a man riding a horse. In the center of the room is a statue of a gryphon. Placing a ceramic egg at its base opens one door, placing a ceramic horse opens another. There may or may not be a way to open the third door.

- Memory Games

On various murals throughout the dungeon, you have a series of symbols, always in the same order. For example, triangle, wavy line, crossed circle. Then you get to a room with five  bas-relief symbols that are obviously buttons. The symbols are crossed circle, cross without circle, square, triangle, wavy line. Pressing the right buttons in the right order triggers something, such as a secret door.

Another example are the puzzles in Skyrim. They have a few standard symbols based on animals or creatures, and some rotating pillars or rings with three symbols on each. Somewhere nearby, there is a set of fixed pillars showing the proper order, or there are symbols on a "dragon claw" used as a key. This is actually easier than the puzzle described above, because the solution is never very far away, unless you find a door that requires a dragon  claw that you don't have.

What I'd suggest is that riddles, if they are used at all, are best restricted to clues for any of the puzzles above. They are an extra help on what to do.

Barony Development

"Well, it's like in the Army, you know? The great prince issues commands, founds states, vests families with fiefs -- Inferior people should not be employed."
--- Firesign  Theatre
Now here's where I try to get really clever with adapting the magic research rules to all sorts of other things: barony development. Famously, Underworld & Wilderness Adventures brought up the topic of domain management as the D&D "end game", but only offered sketchy details: "Some  possible  investments  are:  Road  Building, Canals, Inns, Hunting, Religion, Armories, Animal Breeding, Farming, Fishing, Exploration, Ship Building, Sea Trade, Land Trade,  Trapping. Successful  investments  will  also  have  the  effect  of  increasing  the  population  of  the investor's  territory,  providing  the  area  of  investment  does  not  specifically  preclude such  (hunting  and  trapping  would  do  so,  for  example)." Many people have tried to flesh out those details, for example the designers of Adventurer Conqueror King, but most aim for logic and realism, working out economic details. I don't want that kind of grief, myself.

The simple way is to again define each feature in terms of levels, much like the holy shrine or the arcane library. In fact, each of those could be considered examples of barony investments. The baron spends money raised by taxes, with the intent of raising the level of the resource, and makes the research roll, with success meaning the level improves, winding up with a 1st level road network, or 3rd level trading.

For commercial resources, the level determines income. Trade, for example, brings in profits, which can be taxed for extra domain income. Since the base tax is 10 gp per citizen, you could figure that 1st level trade brings in 1d6 extra gp per merchant or tradesman. 3rd level trade brings in 3d6 gp per merchant.

The level could also be a target number for 1d20 rolls when trying to produce some specific resource. Say you invest in lumber, and suddenly need a supply of logs to build a palisade. Roll 1d20 less than or equal to your Lumber level to meet that need.

Legendary Weapons

I'd already mentioned Andy Bartlett's post on zero-level NPCs using magic as one of the the things that sparked this recent discussion of re-purposing the magic research rules for many other things, from adding new mundane skills to building shrines and libraries. But one of the other inspirations was a forum discussion about magic weapons and armor that are legendary rather than enchanted. They became powerful because they were used in great deeds, not because they were made by a wizard. In the forum thread, I outlined this idea:

Giving your sword or weapon a name is the first step towards making it legendary. A master smith must etch the weapon's name into the blade or shaft, perhaps adding a gold or silver inlay. The amount of money spent affects the odds of the weapon becoming legendary: 500 gp for a 1 in 20 chance, plus 500 gp for each additional 1 in 20. Double the cost for a +2 weapon, or quadruple it for a +3 weapon.

You don't roll during the crafting, but instead during combat. When you strike the deathblow on a monster that's a higher level than you, roll to see if the weapon becomes legendary. Or, combine this roll with the attack roll: it becomes legendary on a perfect 20 roll for the death blow, or a perfect 19+ if you paid the extra 500 gp, or a perfect 18+ if you paid 1,500 gp and so on.

Once it becomes legendary, the GM secretly rolls for intelligence and possibly ego, perhaps using only 1d6 to start. Each additional legendary deathblow gives a chance for the weapon's intelligence to increase, and thus have an increasing chance of communicating with the hero and/or developing powers. To add specific powers, take the legendary weapon back to the smith to inlay some runes on the weapon for another magic research roll, the cost based on the effective spell level of the desired effect (flaming swords might be 3rd level, a sword that summons storms would be 6th level.)

These costs do not have to be ornamentation by a blacksmith; that's just an example. It could instead involve performing rituals and using rare magical substances, or paying bards to spread rumors about the deeds of your mighty blade. Also, you can set maximums for the plusses on a weapon, or limit intelligence to magical swords as per the rules as written, or require a minimum character level before a weapon could become legendary.

Arcane Library

Continuing the discussion on re-purposing the magic research rules for other things: the way holy shrines work is itself a re-purposing of some  ideas I have about arcane libraries. Some variations of magic research allow reduced research costs if the magic-user has a library available. I thought about including the cost of the library as part of the cost of research, but that makes it easy to build up a library that guarantees success when researching 1st level spells.

I decided instead that it's easier to assign levels to arcane libraries. A 1st level library lets you research 1st level spells, but not spells of 2nd or higher levels. A 5th level library lets you research spells of up to 5th level, but not those of level 6+. The library's level acts just like a shrine's level: it doesn't add to the chance of successful spell research, it just sets a minimum target number. As long as you spend the minimum required on spell research, a 5th level library gives a 25% chance of success.

A hypothetical arcane library that would grant automatic success to spell research would be 20th level and would cost a minimum of 262,144,000 gp ... and you have only a 1 in 20 chance of successfully creating the library, at that cost. Spending 5,242,880,000 gp would guarantee that you'd get a 20th level library, assuming that's even possible. Perhaps max library level would be max spell level? Even if it isn't, 260 million plus in gold pieces seems like an unreachable amount, even in most Monty Haul campaigns.

If someone steals a wizard's magical tomes or sets fire to the library, the value of the lost materials lowers the library's level. How you handle this wouldn't be set in stone, but for example you might rule that a thief could grab 1d20 x 1,000 gp worth of tomes at a time, or an out of control fire would lower the value of a library by 1 level every 2d6 turns. It all depends on what seems right for the given situation.
