Miscast tables: now in a single PDF!

I compiled my miscast effects into a PDF! It's an 8-page booklet, and I think I did an okay job with the layout, too, so if you print it out, each table occupies a single page or a single spread.

or

Get it from my itch.io page (free/PWYW)


6x6 miscast effects for
- Metamagic
- Teleportation/dislocation/polymorph type spells
- Illusion and invisibility spells
- Mind altering spells, charms, telepathy
- Elemental-, energy- and nature-based spells
- Necromancy and life-force altering spells

I turned mine into a little saddle-stitched thing. Feels good.

ALCHEMY! A system for weird experiments


An alchemy system, written for this month's RPG Blog Carnival!

The following tables present a subsystem for alchemy in OSR games, taking LotFP as the base (so, all prices are in silver standard – if your game uses gold standard, just replace “sp” with “gp”). For Laboratories, see LotFP: Rules & Magic, p. 82-83.
The system is intentionally convoluted and baroque. Like any good old alchemy, it is untested, volatile, and unpredictable! Use it as written, or just steal ideas from it, as usual! Have fun!

Miscast table: Energy, force, and nature

More miscast tables! This time for all spells concerning the manipulation of natural forces and energies. I will probably try to finish two for tomorrow, or maybe all that's left, and compile them into a pdf!

Elemental-, energy- and nature-based spells


  1. The mundane version of the invoked element becomes hostile towards the caster for 1d6 days. Campfire burns them, water flees form their mouth, light blinds, winds crash their ship and branches tear their clothes, etc. The severity of these assaults is up to the Referee (and probably also depends on the power level of the intended spell).
  2. All metallic objects in a [caster level times 10’] radius become electrified and discharge with a painful electric shock. Everybody touching, wearing, holding such an item must save against Devices for each such item, or take 1 (for jewelry), 1d3 (for metal weapon), 1d6 (for chain armor), 1d12 (for plate armor) damage.
  3. Natural order is disturbed in a [caster level times two miles] radius area around the caster. Natural order is restored in [caster level times 1d6] hours, but consequences remain. Roll 1d4:
    1 the air becomes thinner, oxygen saturation drops. Everybody gains 2 points of Encumbrance while in the area of effect. Characters with a negative Constitution modifier must save against Paralyze at the end of every hour or fall unconscious,
    2 the freezing breath of the White Worm or perhaps Ithaqua sweeps through the area; temperature of air drops significantly (e.g. from summer warmth to winter cold, from winter cold to Arctic),
    3 the sun becomes a red monster that devours men, seeking them out with heat rays; both indoors and outdoors temperature of air raises significantly (e.g. from mild spring to unbearable summer, from unbearable summer to apocalyptic heatwave),
    4 magnetic disturbance: all metallic objects (including weapons, armor...) drop to the ground, can be only lifted and carried or worn as five times their usual Encumbrance value; keep in mind, this means even metallic parts of non-metallic objects – like nails keeping a boat or wooden construction together.
  4. [Caster level times three] Magic Missiles rain from the sky or appear out of thin air. Everybody in a 60’ radius must save against Breath. Distribute the missiles between the caster and those who failed their save. The caster doesn’t get to save, they are hit anyway, but maybe their comrades or enemies take some of the damage…
  5. Phlogiston saturation increases significantly in a [caster level times 30’] area. All open fires explode violently, and everybody holding or standing near such a source takes 1d4 damage. On a damage roll of 3 or 4, they also must save against Breath or catch fire. Burning creatures take another 1d4 damage on the next round, and if that is a 3 or 4 too, they are engulfed in flames and begin taking 1d8 damage until put out. Putting out flames in the phlogiston-saturated environment takes twice as much effort.
  6. Space swallows itself and a black hole opens in a maximum of [1d6 x 10’] from the caster, in a random direction (roll 1d6, 1 below, 2 through 5 is north-west-south-east, 6 above), but in the same general area. The hole remains open and active for 1d6 rounds. All loose objects and creatures in the vicinity are sucked into it at a speed of 20’ per round. A save against Paralyze can be made to grab onto something. If the initial position of a creature relative to the black hole cannot be determined, they are [2d6 x 10’] apart.

Miscast table: Illusion spells

I'm creating custom tables of miscast results for various types of magic. I could use the standard D&D division of magic schools (Abjuration, Evocation, etc.), but I've decided to go with six similar, but slightly different categories, that sort of make sense to me and fit the spells in Lamentations of the Flame Princess:
  • Teleportation, dislocation, movement and polymorph type spells
  • Illusion and invisibility spells
  • Mind altering spells, charms, telepathy
  • Elemental-, energy- and nature-based spells
  • Necromancy and life-force altering
  • Metamagic (spells affecting or modifying other spells or spellcasting abilities)

I will be posting them as they are completed. For the first installment, I present you the illusion miscast table, heavily inspired by theories of light.

Miscast effects for illusion and invisibility spells


  1. Those newfangled scientists say vision is the perception of light reflected from objects. For the following 1d6 months, the caster is physically hurt by looking at certain materials. If the caster looks at a surface that is at least palm-sized for longer than 1 round, they take 1d6 damage. Roll 1d6: 1 steel, 2 wood, 3 linen, 4 paper (ouch!), 5 gold, 6 human skin.
  2. The trusted old school scientists say vision is possible due to the human eye emitting special “eye beams” that trace the world around us. The caster’s “eye beams” become lethal death rays for 1d12 rounds. They burn through organic matter (including the caster’s eyelids) for 1d6 damage per round, but don’t set things on fire. The “eye beams” have a range of [caster level times 10’]. Mirrors and other shiny surfaces reflect the rays in a random direction – if there is a lot of this going on, everybody in the area must save against Devices every round to avoid being hit. While this effect is on, the caster is effectively blind. After the duration of the effect, the caster remains blind for 1d6 days.
  3. According to the corpuscular theory, light is made up of minuscule particles called “corpuscles”. They now hate the caster. For the following 1d10 days, anytime the caster does something that requires vision & concentration (aiming a weapon, reading, scouting), the corpuscles play tricks and the caster just cannot achieve anything unless they successfully save against Breath.
  4. The caster’s perception of reality is warped for 1d6 hours. For any object or person they encounter the Referee can roll 1d6, on a 1 the caster is adamant it is an illusion and refuses to think otherwise. Any illusions encountered during this period is automatically believed.
  5. People’s shadows are slaves! The caster’s shadow breaks free of its shackles, and is now a cunning, dangerous monster. HD = [caster level], AC as leather, Move as unencumbered human, Morale 8, 1 soul-rending attack for 1d3 damage [1d6 if HD > 5], immune to physical damage, but can be tortured with bright lights (torch or stronger do 1d6+ damage). A super bright light triggers a Morale check. The shadow can either use its attack or try to break free another shadow slave. That shadow’s master must save against Magic. The shadow knows who has the worst save.
  6. The caster becomes Visible for 1d6 hours. This is a sort of reverse Invisibility... It means that the caster is seen by everybody in a [caster level times 10’] radius. They are literally noticed through walls or in complete darkness. No material can block Visibility.

[LotFP] Extended laboratories for research


This post is a collection of things a high-level wealthy Magic-User can use to stock her laboratory and library. This is mostly for flavor, extending and fleshing out the abstract approach of the Lamentations of the Flame Princess rulebook (p. 80-83). With a distinct early modern science feel.

Cabinet of curiosities

No laboratory can be complete without a nice collection of curiosities! 

Strange creatures
Creatures preserved as skeletons or taxidermic mounts can be added to the cabinet of curiosities. The preparation of such objects requires special knowledge and skill. For taxidermy, the corpse must be relatively fresh (1d6 days after death). For skeletal mounts, most of the bones must be present.
Where to find: Collected personally or purchased from adventurers.
Price & value: Depends on the type and hit dice of the creature.

Type
Price & value / hit dice
Common
50sp
Exotic
100sp
Supernatural
250sp

Samples
Minerals, gems, jewels, crystals, stones, metals and ores, various substances (resins, oils, liquids, etc.); and also seashells, corals; butterflies, insects.
Where to find: Collected personally or purchased.
Price & value: If the value is not evident, set it as 1d10 x 10sp.

Medical oddities
Specimen displaying signs of illnesses, pathologies, malformations. Usually preserved in fluids, displayed in glass jars.
Where to find: Purchased from medical facilities, collectors, unfortunate parents...
Price & value: Depends on the rarity and state of preservation: 2d10 x 25sp.

Exotica
Curios and various objects from faraway lands. Masks, costumes, jewelry, paintings, drawings, dolls, puppets, idols, art pieces, musical instruments, anything.
Where to find: Collected personally or purchased from merchants, travelers, agents. Good connections with trading companies can give the opportunity of first picks from any haul…
Price & value: Calculated based on the distance the object had to travel to get to the collector. Add 1d10 x 10% on top of that for agents’ fees (only added to the buying price, not the value).

Distance & complications
Price & value
For every 100 miles over 500
50sp
Transportation included both land & sea
+100sp
The original owners of the object would kill to get it back
+100sp

Laboratory equipment

A well-equipped laboratory must include a wide range of vessels, both simple and complex, which can be used for sublimation, distillation and other processes. Including, but not limited to:
  • alembic – two vessels connected by a tube, used for distilling chemicals
  • aludel – clay subliming pot, made up of two parts
  • athanor – a special furnace that provides uniform and constant heat
  • crucible – a small vessel or container that can withstand high temperatures
  • “Moor’s head” still – distillation apparatus, with an extra vessel for cooling water
  • mortar – for grinding up various substances     
  • retort – spherical vessel with a long neck, protruding downwards
Where to find: Most of the equipment is available for purchase only in major cities. Some pieces are produced on special orders.
Price & value: Any amount of money can be invested into this sinkhole…

Extended and specialized laboratory spaces

These rooms are counted towards the value of the laboratory as usual, but might give situational advantages (a bonus on the Magic save, etc. – Referee’s discretion).
Additional space is a one-time extra, counted over the base space requirement of a 10 feet square / 1000sp value.


Additional space required
Price & value
Anatomical theatre
50 feet square
>3000sp
Animal kennels
none
100-500sp
Botanical garden

[Magic Item/Book] Tome of Higher Constellations

The Tome of Higher Constellations was created by an anonymous scholar in Prague, for the library of Rudolf II. The first half of the book consists of astronomical tables: meticulously compiled and corrected, but nothing out of the ordinary. However, the second half introduces more charts, graphs, from a wide range of sciences natural and occult. Through complex calculations these are cross-referenced with the heavenly constellations. Uncanny patterns, otherwise hidden, emerge… making it possible to trace and predict the finest shifts of the celestial spheres that command the fate of the whole universe. The final result is a single date in the future, when all factors align, and major, cosmic changes are possible. Actions undertaken on that day will bear major consequences: warlords bent on world domination crave to know this date, alchemists and magicians seek it as the date of their opus magnum or most complex ritual…

The catch: this prognosis is not descriptive. It’s prescriptive. Once a date is divined using the Tome of Higher Constellations, something world-changing is bound to happen. But the exact details are malleable. Anybody who knows the time can attempt some insane endeavor.

To peruse the Tome, one must have a strong academic or arcane background, and then spend 2d4 weeks working on the calculations in a library or laboratory.

After the period of study, a date in the future is predicted.


Dice type
Time unit
1
1d4
days
2
1d6
3
1d8
months
4
1d10
5
1d12
6
1d20
years

Roll two d6’s and consult the chart. The first d6 gives a dice type. The second d6 gives a time unit. A roll with the given type of dice defines the amount of time units.
Example: roll #1 is 3 = 1d8. Roll #2 is 5 = months. The 1d8 roll comes up as 6. This is combined as 6 months.
Repeat this process two more times, then sum up all the results to learn how far into the future will the grand constellation take place, counted from the FINAL day of work with the Tome.
Example: #1 = 6 months; #2 = 8 days; #3 = 12 years. The constellation will take place 12 years, 6 months and 8 days into the future.
If one time unit comes up more than once, just add them up as usual.
Example: #1 = 6 months; #2 = 13 months; #3 = 2 days. The constellation will take place 19 months and 2 days into the future.




Yeah... This is how I envision "epic level" games in LotFP, mwhahah...
